Clear View Filtration DOES NOT RECOMMEND ANY MODIFICATIONS to any of our Filter Assemblies. We will also not be selling any filter bases separately for people that screw-up the filter trying to modify the by-pass pressure relief valve or base in any way. This is because we don't know how modifications would affect the filter tops without testing.

Clear View will not be making any changes to our by-pass (or filter base) design because of the concerns that have came up just recently. We believe that the current design is the best. We want to by-pass oil if either filter media was to restrict oil for any reason.

Again, we are Sorry for the doubts about our Products and for any inconvenience to our loyal customers caused by all of this.

These are pictures of a Moroso disposable Spin On Filter that one of my customers brought to me at last year’s PRI show. As you can see it has rubber crammed into the inlet passages of the filter. I told him to take it over to Moroso and ask them what is that rubber stuck in those holes? He came back and said a guy at Moroso took one glance at it and handed it back and asked if he had an accusump on his car. Customer replied yes and the guy at Moroso told him that the electric valve on the accusump was bad. My customer said he took that valve off the accusump when he put it on his car. Moroso said when he shuts his engine off the oil from the accusump is feed backwards through the disposable filter then directly into the oil galley, pushing the rubber diaphragm that makes sure the oil flows around and through the filter media rather than to the center of the filter is what was stuck in the holes. Moroso also said when you start your engine the rubber should push back in. I, personally would not chance my +/- $50,000 motor that’s going to happen. My customer said he ran it for months like that and never hurt his motor. We talked that the Clear View Filter by-pass that was by-passing his disposable filter probably saved his motor.

As anyone that has talked to me about hooking up an accusump to their motor knows I recommend to feed it into the extra inlet port on the top of my Clear View. Because I have redone many engines for my customers that did not clean out the accusump good enough after engine failures. Which then pumped debris directly into the oil galley on a new motor instead of through an oil filter first.

These oil filter pictures show the problem that can happen if you feed oil pressure into the center of the disposable filter first. Bottom line if a person ran a big dollar billet block engine on the dyno or track feeding oil backwards through the filter with a rubber diaphragm stuffed in the holes would probably restrict the oil enough to kill a rod bearing on a mild tune.

I Mike Cofini owner of Clear View Filtration is not a social media person. I hate to say it but I have never sent a text ever and I have a flip phone! Even this is typed with 2 fingers. The only platform I have is the more than 5,000 of Clear View Filtration oil filters out being ran, many of which are on the top teams in all motor sports in at least 6 countries and the 75,000 pounds of aluminum chips Clear View Filtration has made in the last year on my six bitchin Haas CNC machines making the best oil filter in motor sports. There is not one part of the filter I personally have not touched and approved throughout manufacturing, assembly, quality control, testing and technical questions on every Clear View Filter that is sent out of my shop!! For the last couple of days all I have done is talk to people that are now skeptical of my filter because of Josh Tonski’s Post on how his Clear View Filter killed his brand new billet block engine because the Clear View Filter element was clean on the top side and under the element was his bearing debris which he claims my by-pass valve has a stupid design and allowed this to happen! As I explained in my explanations the only way for a dying engine not to put bearing debris on top of the filter element is the filter is plumed backwards. Now I am seeing pictures of modified Clear View Bases because of listening to Josh. Only because someone hooking up there filter wrong. Josh stated he did not hook up the filter lines on his car, someone else did. Clear View Filtration should not have said Josh Tonski hooked up his lines wrong, if it is true he had someone else do it.

I am asking anyone who runs and loves our filters or even those who dislike them to let everyone they can know on social media to spread it everywhere and bring peoples attention to Clear View Filtration face book page, so they can read all the info posted about our filters. Post your experiences and pictures with our filter. Also if any of my Clear View Filter runners have pictures of the filter element when there engine was killing bearings please post them on my face book so Josh can see what his filter would look like when engine bearings start killing themselves and the oil is being pumped through the top of the filter like it was designed to do instead of pumping his oil into the outlet port of the filter base into the disposable filter first. If it was plumbed right Josh would not have made 5 runs or dyno pulls on his new billet block engine because he would of known exactly when his bearings were dying because he would of seen it on the filter element instead of noticing low oil pressure and pulling the oil pan off.

PLEASE HELP ME BRING PEOPLE TO OUR FACE BOOK PAGES, BOTH BILLET CONNECTION AND CLEAR VIEW FILTRATION, SO I DO NOT HAVE TO EXPLAIN ALL THIS S**T ONE PERSON AT A TIME. I COULD NEVER BELIEVE ONE PERSON HOOKING HIS FILTER UP WRONG COULD HURT CLEAR VIEW FILTERS REPUTATION IN THREE COUNTRIES SO FAR AND SALES THAT TOOK 10 YEARS TO BUILD IN JUST A FEW DAYS!!!!!!!!!!!!!!!!!!!!!!!

THANKS FOR EVERYONES SUPPORT!!!!!!!!

This is the Manufacture and Inventor of the Clear View Oil Filters. Josh Tonski and Horsepower Solutions hooked his oil lines up to the Clear View Filter backwards and now blames the Clear View Filter for having a bad design and hurting his engine!

We are a smaller company and I am not on Facebook or social media of any kind so forgive the delay here in response about the claims, comments, and concerns Josh and others have made about the Clear View Filter Assembly. Please excuse the lengthy explanation, I will reach out to those involved with this post, but I will not be going back and forth online about this. My facts speak for themselves and if anyone has any other questions after reading this in full, please feel free to call me directly.

Josh Tonski from Horsepower Solutions this is Mike Cofini, owner, inventor and designer of the Clear View Filtration's See Through Oil Filters. My experience comes from owning and operating an engine shop that built racing and performance engines for more than 25 years and drag racing for just as long.

Josh you purchased the Clear View Filter Assembly from me in 2017. I assume you have been running my filter for the past 6 years or so without any problems, but now you think there is a problem because your motor hurt a pair of rod bearings and other bearings had debris ran through them.

In the video you state you were running your engine and noticed you had low oil pressure and pulled the oil pan off and found a rod bearing problem. Anyone running a Clear View Filter and noticed low oil pressure would take a few seconds to give the filter a quick shot of air and see 100s of particles from a bad rod bearing on the Clear View filter element!!!!!! The Video shows a clean filter element on both sides.

It is impossible to not have bearing material in the Clear View when your engine is dying unless Josh Tonski and Horsepower Solutions had the feed lines hooked up backwards! In the video Josh states there was debris under the filter element. If you hook the line that is the dirty oil out of the oil pump to the outlet port of the filter, it will put all the dead bearing material into the center of the disposable filter then pump oil backwards to the outside of the disposable filter than pushes oil up through the bottom of the see through filter element and into the top of the filter than out of what should have been the inlet port back to the engine. This also explains why Josh said there was debris under the Clear View Filter element.

When a Clear View Filter is hooked up backwards customers call me and tell me there filter does not empty completely allowing the user to see filtered particles. I explain they have hooked up there filter backwards. Josh or any of his followers heard about this problem on this?? Hooking the filter up backwards will pressurize the bottom filter assembly first which pushes backwards on the by-pass valve in the Clear View and cannot ever open like Josh claims is a problem.

Josh this is easy to prove just show all your followers the inside of your disposable filter there should not be any particles in the center of the disposable filter. Drain your disposable filter out on paper towels and show everybody.

If there is any of Josh’s followers that Josh told his Clear View’s filter element was clean on the top side as shown in the video, or his filter did not empty correctly or any one that has doubts or worries about Clear View Filters because of Josh’s posts Please contact Mike Cofini directly at 509-991-3685 or [email protected].

Josh in the video and on your posts you never say there was any debris on the Clear View filter element or show it in the video. You also state its all oily because its fresh of your hurt engine with no particles on the element.

HOOKING THE CLEAR VIEW FILTER UP BACKWARDS IS A COMMON PROBLEM WHATS NOT COMMON IS THE PERSON THAT HOOKED UP THE FILTER WRONG GOES TO FACEBOOK AND BLAMES HIS PROBLEM ON THE PRODUCT AND HURTS THE REPUTATION AND SALES OF A PRODUCT AND BUISNESS BECAUSE JOSH TONSKI AND HORSE POWER SOLUTIONS DID NOT HOOK UP THE FILTER CORRECTLY.

If the Clear View Filter is hooked up correctly lets discuss how the pressure bypass valve works in our filters. They work on deferential pressure between the top inlet port pre filter and the bottom outlet port after the filter element and the disposable filter. We setup our filters to start opening the By-Pass valve at 16 pounds. Meaning when the top filter housing has 16 pounds more pressure pre filter than the lower housing outlet port after the see through filter element and the disposable filter. The only way the inlet pressure does not match the outlet pressure is one of the filters or both are restricting the flow. It does not matter if the oil pressure is 50 pounds or 100 pounds because oil is pushing on both sides of the bypass ball and the spring will keep the ball closed until the top pressure of the filter rises 16 pounds more than the outlet.

The reason to have a bypass valve is if the filter restricts oil to an engine the bypass valve will open and bypass oil around the filter element and keep the engine from killing itself. Most vehicle manufacturers recommend disposable filter for the engine with a by-pass valve. The industry standard is the by-pass should open around 10% of the oil pressure. Which most street vehicles have around 45 to 60 pounds so the filters by-passes are set up around 6 pounds. Street vehicles need bypasses because you might not change oil or filters as recommended and there is no easy way to look into the filter to see how much contaminates are in there, until I invented the Clear View Filter!!

System 1 and Oberg filters also have by-pass valves set around 10 pounds of pressure.

The reason I set our filters higher is because of higher over 100psi racing engines and Hemi type engines running over 140psi with 70 weight oil.

When flow testing Clear View 6” High Flow Filters without a disposable filter and using a 115 micron element on a flow bench running a billet hemi oil pump with 70 weight 55 degree cold oil at 145 psi I could generate around 6 more pounds of inlet pressure over the outlet pressure. Which means there was a slight restriction with cold oil. When the oil was 75 degrees I generated less than 2 pounds more inlet pressure and when the oil was 100 degrees the pressure was the same.

Setting Clear View by-pass valves at 16 pounds insured when starting an engine with cold oil even industrial diesel engines starting up in the winter at below zero temps the by-pass valve will not open and by pass unfiltered oil through the engine.

When testing the by-pass valves and when it would open. I used a custom machined filter base with a bypass oil passage with a line, so I could watch oil coming out of the hose when the bypass opened.
I filled the filter with a lot of dead motor debris we collected out of blown up engines oil pans. To my surprise the inlet and outlet pressure was the same. I than put dirt in the filter covering the element. The inlet pressure rose to around 5 pounds more than the outlet pressure. Then I filled it full of dirt the by-pass still did not open. I had to use a piece of thin rubber and block off three quarters of the element completely at 75psi of oil pressure this opened the by-pass finally. Basically telling me it is almost impossible to open the by-pass by filling the filter with dead bearings and engine parts.

When the by-pass valve opens it only by-passes a small percentage of oil, around 20% on the above
test. The Clear View by-pass valve has a 5/16” hole through it. A #12 oil line has a 5/8” hole through it. So approximately 80% of the oil is still going through the filters when the by-pass is open.

After explaining how the by-pass works lets discuss Josh Tonski concerns about our filters by-pass valve.

A concern I have, is Josh telling his followers things that are not true! On the top of his post he states and I quote “ If you or anyone you know uses one of these (showing a picture of a Clear View Filter assembly) WITH a spin on filter, comment below. I have found a flaw in the design after it wiped out my brand new billet block engine.

In the video Josh states not sure why the rod bearing died but he blames scratches on the main bearings on the Clear View Filters by-pass. He also states he found a flaw in the design after it wiped out his brand new billet block engine. Which is it just scratches in a bearing or show more pictures of your wiped out brand new billet block engine! This is a lie.

Next Josh says the Clear View Filter element because of its small surface area restricts the flow of oil. The 4” filter 115 micron element will flow 45 gallons a minute the disposable oil filter flows 28 gallons a minute. Which means Clear View Filter elements flows more than 50% more oil than a disposable filter!

Last year, Engine Masters did an episode on “Oil Filter Shootout” that we encourage those who can to watch it on MotorTrend, this will help address the filter element and any restrictions it does not cause. They basically tested our Filter against other disposable filters trying to determine which one flowed the best. The bottom line was Our See Through Oil Filter out flowed all the disposable filters.

Josh also states there was debris under the element. That coarse element allows particles of .0025 through the element which would look metallic. The video did not show any debris on the element or under the element.

As far as the modification with a die grinder on the Clear View Filter I would have to say the same thing Josh said in his video and I quote “WITHOUT GITTING ANGREE THAT’S JUST STUPID”

I do not believe the by-pass ever opened on the Clear View. In the past 30 years of building engines I have heard and seen many stories about disposable filter issues and failures. From collapsing the center cone on cheaper filters to methanol making the glue and filter media fail and plugging the disposable filter up.

But Josh thinks it’s just stupid to put a by-pass in the Clear View filter that could by-pass oil if either filter were to plug up enough to restrict oil flow by 20%. Josh would rather only by pass the Clear View filter element that flows 50% more than the disposable filter. Which is always visibly checked and cleaned. Remember a handful of dirt on the element will not open the by-pass. Also you have no clue what is going on in the disposable filter. But Josh thinks it is a good idea to take a die grinder to his filter and put groves under a sealing surface in the filter element. There is no way this will seal at 95psi which Josh says his oil pressure is. This will cause the inner seal to be pushed down into the die grinded groves and flow oil above the seal directly into the disposable filter, bypassing the Clear View element. Basically some oil and particles Josh might want to see will be in the disposable filter. This will also cause damage to the inner filter element seal.

With the Josh mod on his filter if the disposable filter has a problem and starts restricting the oil to his motor , with no way to by-pass the disposable filter. His statements could someday be true that he wiped out brand new billet block engine!

Josh you have ran my filter for 6 years, if you hooked up the filter wrong this time, tell the truth to your followers and I hope your followers put pressure on you and your business to tell the truth. The truth is no debris on top of the filter element means you hooked the filter up wrong!!!!!!!!
You may have hurt my business and reputation more than you know, I am keeping track of everyone that has called me in the last few days concerned about the by-pass in my filters because of your posts. You have hurt my business from your lies and hooking up your filter wrong! THIS IS NOT OVER!!!!!!!!!!!!!!!

Anyone reading this please share it and post it everywhere you can to help other racers using Clear View Filters.

I will try to contact everyone that posted on this site and others or please contact me Mike Cofini directly to voice concerns or info about what you heard from Josh. Call cell 509-991-3685 or email [email protected]. It would be appreciated.

4” and 6” Dry Sump See Through Filter Assemblies
Part # 445-115 - 4" Hi-Flow / Dry-Sump Filter with #16 ports and 115 micron element
Part # 101-115 - 6" Hi-Flow / Dry-Sump Filter with #16 ports and 115 micron element

Billet Connection developed these Patented See Through Oil Filters for dry sump systems and fluid systems using #16 feed lines. These filters have big #16 threaded inlet and outlet ports for use between the dry sump oil pump and the dry sump tank. Having a see through filter before the dry sump tank allows only filtered oil into the tank, which will keep the tank clean and prevent contaminants from going through the pressure side of the dry sump pump. This is also the best place to install a see through filter when the dry sump tank has a flat bottom. Because the particles and contaminants that go into a flat bottom dry sump tank sometimes will settle to the bottom and not be sucked out of the tank and into the filter showing there is a problem in the engine. When the engine is shut off the user can empty the oil out of the filter in seconds to visually examine the filtered particles and the filter element. Examining filtered particles will help determine if they are from normal use or from engine components excessively wearing in the engine. Seeing a problem when it first starts will prevent catastrophic engine failures and expensive repairs.

The 6” See Through Oil Filters with #16 ports has a larger surface area than the 4” filters, and offer the most flow for oil systems flowing high volumes of fluid through #16 hoses. Also recommended when running heavier than 50 weight oil. Can be used on the scavenge side of dry sump systems or on the pressure side of fluid systems using #16 feed lines.

Both the 4” or 6” Filter Assemblies use a #16 O-Ring Boss fittings.

4” Dry-Sump Filter Dimensions: 5" W x 6" L x 3.5" Thick & Weighs 3.9 lbs.
These filters have 2 inlet and 1 outlet openings.

6” Dry-Sump Filter Dimensions : 5" W x 6" L x 3.5" Thick & Weighs 5.8 lbs.
These filters have 2 inlet and 2 outlet openings.
