For those that are following my problems with my 990, I just drained all the engine oil out. I had over 10 quarts of oil (actually a 15W-40/fuel oil combination) in the pan. Almost exactly 2 months ago I drained the previous oil out and put 7 quarts of new stuff in there. I somehow got over 3 quarts of fuel in the engine oil. That is with about 25 to 30 hours of use in that 2 month span.
I plan to wait awhile before I put oil back in the tractor to see what I get when I pull the plug. This happened to my Oliver 1755 and eventually I just had pure fuel oil coming out, had a leak on the outside of the shaft tube in the injection pump.
When I first had this problem, I replaced the lift pump. I still had fuel getting in the oil so I sent the injection pump in to replace the front seals. And since the new injection pump didn't work I put the old one on. From what I could tell the new front seals didn't keep fuel where it belongs.
The other day I took the manifold heater off and set it in a can for a day while it was still hooked up to the little black fuel line. I basically had nothing after 24 hours, although I could blow air through that heater which means it is shot from what I am told.
Can I take my lift pump off and put it in a pan or can for a day or two to see if it is leaking? If it leaks would it leak worse if the tractor is running?
How do I find out where the problem is??
Thanks.
