If the compression is weak or highly imbalanced you will not be able to solve the rough running problem short of an engine overhaul. If compression is good the very next thing that Kent recommends is to do a DIESEL PURGE.

This isolates the control side of the EGR system and is the easiest way to be certain the valve is not being commanded open. There is still the possibility that the valve may be sticking open slightly, or be carboned up causing it to leak by, but this would typically also give you a driveability concern such as a rough idle.

Jan 27, 2020 · I reached out to known Duramax experts and friends Mike Graves at Hollyrock Customs and Eric Merchant at Merchant Automotive for advice on whether or not the truck was worth the $1,800 asking price and if they felt it would make the 1,100-mile trip home with blown head gaskets.
