The 500,000 Mile Compression Test

May, 2012

As my mid-nineties GMC vehicle will likely be surpassing the 500,000 mile mark this summer, I decided it was time to do a compression check of the engine cylinders (5.0 L).  With a brand new compression gauge, all the cylinders read approximately 180 psi.  Knock on wood and all, but I have never even replaced so much as a gasket on the motor.  Yea, I know! Right?
