friend picked up a ford 4500 3 cyl diesel loader backhoe. tractor sat for quite a while and was slightly stuck. bore scope showed cylinders fine, soaked it over night with trans fluid and it is loose now. changed oil and got it to fire up and run, but it ballooned out the oil filter. is there any type of bypass that could be stuck, and if so, where would it be?
 
Releif valve is in the pump... Filter bypass should be in the filter. Sounds like the main releif is stuck.

any way to free it up?, looks like the tractor will need to just about be split to get the oil pan off.
 
Had a Toyota with alot of miles on it that used to pop the filters..I think the pressure relief wore a step in the bore that it traveled and could not go past the step..so was only capable of dumping a certain amount of oil...it would only do it with cold oil, once warmed up it was fine. It just could not open far enough to dump the excessive volume when cold. Let it warm up abit at idle then run the speed up. I would bet it will be fine for the time being. Who wants to rev a cold motor anyways?
 
I believe if you loosen the front bolster and remove the lower bolts so that the gap opens a bit you can drop the pan without splitting her.
I'd probably just replace the pump for all it's worth... but you could try polishing the valve if you don't mind the risk of dropping the pan again.
