As I mentioned a few pages ago... get a oil test done. It’s cheap insurance before you spend the big bucks. It will tell you how much fuel is in your oil or if there’s something else going here.
I hardly think the injectors have anything to do with this fuel intrusion into the crankcase. Many of the proposed solutions so far -- with all due respect to everyone -- seem clearly to unrelated to fuel entering the crankcase.
1. Fuel under sufficient pressure or by gravity is evidently entering the crankcase, is this safe to say?
2. Surely an injector which was dumping enough fuel in the cylinder to remain un-burned and thereby bypass the rings would noticeably affect the way the engine runs, would it not? How could it not?
3. Is there a path whereby the injection pump could actually allow part of its fuel supply to leak into the crankcase? If so, then I guess I would go along with the IP perhaps being the problem.
Maybe I missed something in the earlier posts and if I have I apologize for anything inappropriate in the above.
Where did he buy the fuel parts?Could have popped the seal off the injection pump drive shaft, or some. injectors stuck open when it sits overnight and bleeds off their pressure. My nephew has a 7.3idi with a brand new set of injectors and glow plugs in it. The injection pump is good. He is looking to sell the parts off of it cheap just to get back some of the money he put into it. I ended up doing a cummins swap for him. If anyone need some parts off of it let me know. Good luck with your truck.
Well today on incompetent garage...
I named the truck Lenny from of mice and men. He keeps accidentally breaking things on me and though it's not his fault if he keeps doing it I'm going to have to kill him.
I'd say definitely yes. You have over 200,000 miles on them. That's a lot of movement of internal parts. I don't know how the veggie oil affects them, but they're generally known to last around 120,000 miles give or take.I have a 94 turbo IDI ... got it with 128000 miles 5 yrs ago.
It now has 334600 miles on it and i run straight veggie oil in the 7.3, do you think i need new injectors ?
