gearhead204 Posted July 16, 2014 Share Posted July 16, 2014 drop the exhaust manifold and look for the "clean" port that will tell you which head to pull also check the oil pan loosen the drain plug and check for antifreeze if found do main and rod. brgs. also.

wheeler73 Posted July 16, 2014 Share Posted July 16, 2014 What year and engine is in the truck? MP engines also have injector cup issues. Have also seen some E-tech and ASET injector cup issues which is rare compared to the MP. 1 Quote Link to comment Share on other sites More sharing options...

bbigrig Posted July 18, 2014 Share Posted July 18, 2014 I have had an MP engine pushing coolant out of the expansion tank due to injector cup failures.( That and doorknobs that install them poorly at the dealer) Quote Link to comment Share on other sites More sharing options...
wheeler73 Posted July 18, 2014 Share Posted July 18, 2014 Lol Bbigrig so true! Unfortunately most so called techs don't take pride in their work and are nothing but parts changers. It gives the rest of us techs a bad name. Unfortunately now I do not get to repair most trucks as I am the triage tech and only diagnose them anymore. I miss the engine work as that is my favorite. Oh well someone needs to diagnose the trucks for the parts changers. 1 Quote Link to comment Share on other sites More sharing options...
