case backhoe fuel in oil
I hope that I am putting this in the right place...
I have a older case 580 case construction king hoe. It has a 4 cyl engine. It is getting fuel in the oil bad. Does anyone know where to start? I have heard that there is a o ring or something that goes bad on the injectors. Does anyone have info that might help me out? thanks ahead of time, Eric

if it has a manual style pick up pump on the side of the block, it could have a bad diaphram in it and the fuel will run through and into the base , I have had this problem with my old massey( both have perkins engines) 2x now so I quit using that pump and installed a electric 7psi pump does it do it when running or just sitting? mine would drain the overhead fuel tank and put it all into the base till it run out the dipstick tube

If it is an older Case hoe like you said, It is probably a B,C, or D model. If this is the "case" no pun intended, it has a Case engine with a RoosaMaster injector pump. (Now called Stanadyne) There are two seals on the input shaft of the pump that resemble a butterfly when viewed from the side. (Of course the pump has to come off.) Those seals ride in a bronze bushing bore on the inside of the pump itself. The pump will slide off the shaft, leaving the shaft attached to the gear. Those seals wear out, and sometimes leave a groove in the bore. Have it checked and replaced if necessary. The seals themselves are cheap, so if you think you might have screwed up when sliding the pump back on, its best to just replace them then before you finish and have to do it all over. It's not that hard of a project, just takes time.
