My injection pump bumped a bunch of diesel into the oil. I was losing oil pressure driving home and I just thought it wad the gauge being stupid...drive probably about 12 miles our so with no oil pressure. Got home and checked the oil and it was full of fuel. So I got the new pump and all and was just wondering if I should be worried about the engine.

I wouldn't see why you would of lost pressure.

But, for a short distance it should be fine. Diesel fuel has pretty good lubrication in itself. How much diesel are we talking about?

I would'nt run the new oil very long then change it again to flush out the fuel. If the oil pressure goes back to normal and the engine sounds good, i'd say its probably ok. Probably good you did'nt drive it much further.

Would'nt hurt to put some lucas in the oil the next couple changes.

Are you sure the lift pump was the problem? Thought I'd add that the injection pump can do the same thing.:thumbsup:

I think it is my injection pump man...i'm pretty positive outs the pump cuz there was diesel running down the side of the block and the timing gear...I've got the new pump I was just worried about my bearings and stuff

Might be a good idea to get a oil test done if it at all seems like there is a problem after you change the oil filter. They can tell what wear metals and how much is in the oil.

Because the diesel thinned the lube oil. It greatly reduced the lube oil's viscosity thus it's ability to stay in the bearing and support it's load.

With the thinned lube oil, the film of oil that supports/separates the bearing assembly, .. . .. can't. The result is wiping of the babbit material from the bearings.

As has been mentioned, short of taking the engine apart and inspecting the bearings, renew the lube oil and hope the gauge presents with a reasonable pressure with no knocking upon restart.


Good luck.

It goes in a ways. Did you find the pin? The knob that sticks out should stick out some once its locked into the hole in the gear.

Yea I'd say it just fell out. All it is is a plastic piece that is held in with a rubber o-ring. As long as you get the hole in the gear centered perfectly with the timing pin hole you'll probably be ok. You might have to get a small mirror to see in there. Or if you know someone else with a 1st gen you could see if they'll let you borrow theirs.

Can you use a small screwdriver or awl? I have not had to do this yet, so I do not know the clearance for such things.

A small phillips or awl will work I've done that before, sometimes it was easier that way then with the original pin.
