Never posted here before and know very little bout the 6.0 engines but..Friend has these plugs leaking and engine wont run."another" forum told him to remove valve covers and change the stand pipes and o rings to the plugs. Does this sound right? I know my 7.3 idi but just have no hands on experience with the 6.0. I have seen what The Diesel Treat has posted bout all the exciting work he does on these engines.
