Re: 86 Silverado K20 12V CUMMINS Build

So at this point, again more cleaning by the kid with the pressure washer.



Then started stripping the frame of all exhaust and drive train.



Now just before we pulled the engine we drained all the gas and ran it dry. For some reason I decided to compression check all the cylinders. Well this was the first surprise. All had between 175~180psi except #5. It had 65psi. CRAP.
Tore into it right away...



Yup, that is cracked piston between the rings and broken rings. Double CRAP.
Oh well back to the frame...
