Haven't really been on Facebook or taking pictures. Here's a motor swap I did recently. Orange car was totaled and the black one didn't run.

05 f150 3v 5.4

So, dropped the oil pan and pulled all the plastic out and cleaned the pickup tube out. Had to replace the oil pan due to something breaking one of the scrapers in the pan off and putting 2 holes in it that someone has tried to patch with painter's tape and JB Weld... Lol. New pan gasket and timing components going in.

I work on all kinds of things. This trailer had a bent axle and a broken spring (from overloading it) so it got a new axle and thicker springs. Also added brakes and welded on a new swing away jack.

Vehicle maintenance is extremely important. Mid 2000s 4.6 and 5.4 3v v8s are known for breaking the spark plugs off in the head. The back 2 plugs were nearly seized while the other 6 came out buttery smooth with anti seize on the threads. The back 2 are hard to get to but no excuse to not replace them. Luck was on my side and I was able to get all 8 out without breaking any. This truck is in for a bunch of repairs so more posts to come about it.

Guy called and said he paid some website that gave him a list of mechanics and I was the first one listed.. had no idea what he was talking about but whatever, I'll take it. Water pump, spark plugs, and wires on an 07 impala this evening. Message or call with your needs. I can usually do same day appointments.

I was called out to diagnose a loud rattle on 2010 Acura RL on 5-24-25. My prognosis was a failed timing belt tensioner. I instructed the owner they shouldn't drive the car, and told them I was free that evening to do a timing belt/water pump job. They insisted doing it the next day, to which I said it's not a good idea to drive the car until this is fixed. My warning fell on deaf ears... 8:51am on 5-25-25 I get a call the car shut off on the interstate. They insisted it was the serpentine belt I had removed the day before to prove it wasn't the serpentine belt tensioner and in fact the timing belt tensioner. I show up, serpentine belt is still on. They now want to tow it to my shop and do the timing belt kit. I forewarned them that these are interference motors and that just replacing the belt may not get it back running as it has previously. They wanted to move forward. In hindsight I probably should've scoped the cylinders for damage but I wasn't trying to argue about an hour of diagnostic time with them, they were adamant replacing the belt would fix it. Belt kit installed, car runs... But only on 3 cylinders. I tried to save this one but the rattle won this time. I love doing timing jobs, they're probably my favorite thing to do but my famous last words will always be: do not ignore the rattle. Trying to delay the inevitable will only cost you in the long run. And with that, c'est la vie. Onto the next one. I wish them better luck in the future and this was an expensive lesson to learn.

Still working on the speed 6. Broken pedal assembly causing the pedal to not return fully. This will be the last thing I do to it, for now. Laid down a couple more welds for good measure.

Mazdaspeed 6 came in with the coolant full of oil. Customer thought it was a blown head gasket. After some diagnostics, I determined it was the oil cooler leaking into the coolant. Much cheaper and easier job than a head gasket! Spent quite some time cleaning oil out of the coolant system as well. This car was brought to me because the customer lost trust in their previous "mechanic" who told them the oil cooler was fine and that it was the head gasket. Lots of mediocre work done here. Still fixing stuff.

Dead starter replacement on an 04 BMW 330ci today. These can be a little time consuming due to not being able to access it from the bottom and a lot of things having to be removed up top to get to it. Replaced a couple of extra worse for wear items at the same time, like the crank case vent tube and the upper intake boot. Got it wrapped up and running without any problems. I'm extremely familiar with inline 6 BMWs as that's what I started learning on when I first got into this field. Message, text, or call to get on my schedule for repairs or maintenance. I do it all.
