my truck dumps white smoke, leaking oil, oil in my exhaust, and when i remove the cap of my fuel injection pump the liquid under it is milky. Do i have a cracked head or a blown head gaskit??? and what should i do for either problem?

 

Im not familiar with the 6.9L IDI, but white smoke is also unburned fuel also, or a sign of leaking antifreeze I would see if you exhaust smells sweet or if it smelled like raw diesel. Now if you have oil coming out of the exhaust it could mean you have a worn cylinder, cracked head, bad valve. ECT, ECT. Best place to start is to perform a cylinder compression test, see which side has low compression and tackle that side. If its a blown head gasket simply remove head, clean block and head, and inspect the head and move on with life. If you have a cracked head then well.. You need a new head, and head gasket. But if you have low compression in a cylinder, when you do the compression test see if you can see oil or any containments or damage in the cylinder. Hope that I was some of assistance.

 

Thank you so much. i will get right on that and i will let you know which problem it is.

 

LOL>.. You make this sound easy ... I did that in my truck and guess what ... now I have the engine out ...

its a 6.9 and it most likley just hasnt been driven enough to remove the moisture from the oil, short trips and such will do that ...

 

I try just the lack of wanting to write a manual..

 

LOL... hey if you know something never be afraid to write it out... I have lots of knowledge, some good, and some just more oppinion based ..

that being said , Please, if you ever have input , lets hear it ..

 

I try, most of my experience is with B series cummins and Heavy Trucks..

 

I hear ya, i build 6V-S60's .. occasionally a Kitty..

 

Ya work on them all they way through from Bumper to Bumper. Most of my builds have been B series and DT466e. No kitty cat yet.

 

i have herd many gret things about the dt engine line ... and of course the B is ALWAYS da bomb .. and simple too ..
