Different and fun project we have going on!

Customer came to us with worries of a cracked block on this 454 big block Chevy that was in their boat. With the engine out we began the tear down to find the problem!

We drained over 32 QUARTS of oil/water mixture from the engine oil pan (this engine is only supposed to have 8 quarts of oil) Cylinder 2 was FULL of water indicating a blown head gasket or cracked block for that cylinder. We removed the heads and found the failure point was in fact the cylinder block cracked. Due to the massive amount of water in the engine we also found some bent pushrods due to hydrolock.

Rebuilt heads are ready and a new short block with new valvetrain components are on their way and soon this customer will be ready for summer days out on the lake!

Stay tuned for updates!

Lets talk about diagnostics!

We don't guess here at JBC Auto & Diesel - we diagnose.
Our advanced automotive diagnostics skills and tools allow us to find your problems faster and fix them right the first time.

Modern vehicles are computers on wheels. This makes diagnostics more difficult and time consuming, unless the proper tools are being used. Here at JBC we use top of the line diagnostics equipment that does not just read a code or turn a light off, but that can access all systems of your vehicle and gather real time data from your engine or powertrain to help identify and isolate the cause of your check engine light.

Our mobile services will bring that high quality and thorough diagnostics right to your doorstep! Don't drop your vehicle off for days at a time when the shop can come to you on your schedule!

Call us today at 720-250-8606 or visit our website jbcmobile.com to book online!
