lotsa fuel in my oil

[busybeazz]

as stated i have diesel fuel in my oil and will over flow out the oil overflow tube .I have changed fuel pump . and changed oil with new filter ran for 1 hr and it did it again .so i have removed the injector pump and taken it to a reputible shop and they gave me an estimate for $550 to rebuild but said it was not leaking but it was worn . can it leak under pressure or wat ? im confused so i am stumped. they are checking injectors as well but no word on them yet.its a B20

Not sure about your engine but most tractors have a mechanical lift pump attached to the side of the engine. It can leak into the crankcase from there. Allot cheaper fix than the IP.

i have all ready changed the fuel pump that was my first option .i use the tractor almost daily starts easy no un usual smoke .alltho before i changed the pump it had become harder to start and after the pump it started starting easy and ran better then it has in a long time .could there have still bin diesel left in the upper part of the engine after i changed the oil .i do not believe this can happen as i left it to drain for 2 days wile i was waiting on the new fuel pump to com in .the tractor only has 850hrs on it if fuel was leaking by the rings this much would it not basicly b flued and b able to hear one cylinder not running any help would b helpful . i am also going to have a oil sample dun monday . it spills out the overflow at hi rpm and is definatly overfilled

Please explain what you mean by overflow?? I was assuming you meant the dipstick but I am not sure what you mean.

there is an overflow tube on the valve cover and at high idle it spits an unusual amount of black oil enuff to leave a black trail on the ground b hind me

OHHhh. Now I understand. Sounds like your rings are shot and or your oil has changed to diesel and is passing by the rings and going out the "breather". Is there allot of crankcase vapor coming out the breather too?

i don't no ill have to put it back together after i git parts back from service Monday. would it run so good with bad rings ? it only has 850 hrs i would not expect it to have bad rings all ready .but they are hard 850 hrs. how do you check compression on a diesel . do you remove injector and put compression tester in injector hole

Vic and Kuboman have given some really good advice. Here is a link to a thread that can give answeres for compression testing.
