Can we get a sticky for reasons for trucks making oil? It seem to me its a common enough of a problem to track it. It seems several different things can go wrong with the injectors. I'm now finding out about injection pump issues that can make oil. What else? Post up if you've had issues with your fuel system filling your crank case.

 

Great info. Just what I was looking for. Thanks!

 

+1, I've used them. Very reasonable price to know whats going on in your block.

 

here's what my 2006 is doing, LMK what you guys think, it is stock, except for a Boost Fooler & a cat back (simple 4 inch & straight thru muffler)

-bad vibration/missing/shaking (quits after while) after sitting for week or so. (we don't drive it much, so take it out once a month, and it acts up.)

-oil is getting over full, not much this week (just changed oil) but the last time i checked it & changed it, it was pretty high.

-has started blowing coal - a LOT LOT LOT more than it ever did (this seems to clear up the shaking/missing, when you WOT it for 2~3 seconds)

so, from perusing DTR and the above thread, it could be:
-injector stuck open (explains smoke, but does not explain why the miss clears up after a WOT)

-CP3 leaking internal, ????

-do the injectors crack and spray fuel internal to the engine? then why stumble and have extra smoke?


my buddy is saying just put some LUCAS or something in it, it is prolly a dirty injector, and that will either clean it out, or unstick it?

what to do?
