Onyx610 Posted September 17, 2022 Share Posted September 17, 2022 Possible head gasket? I know the Cummins nt855s used to squeal or chirp when the head gasket went or head bolts stretched. They were seperate heads like Mack’s and not a slab head. 1 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted September 17, 2022 Share Posted September 17, 2022 Do a coolant pressure test tomorrow and really look for any visible leaks. If you do not find any it’s time for a compression test…. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 17, 2022 Share Posted September 17, 2022 so its an ASET-C... lots of places to loose coolant.. head gasket is surely possible Quote Link to comment Share on other sites More sharing options...

The inside of the pipe is black but sometimes blows white smoke & stutters when I take off from a stop, usually around 4th gear.

Joey Mack Posted September 17, 2022 Share Posted September 17, 2022 white smoke is coolant, typically... is the egr cooler bad? Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted September 17, 2022 Share Posted September 17, 2022 so you dont see any stripes of burnt coolant on the engine block.. pinkish whiteish streaks? unless you are using green or yellow coolant.. you still would see streaks of burnt/dried coolant..

It’s the weirdest thing but when I had the exhaust manifold off the injectors all had a white coating on them of something, is this normal?
