Hi, I bought a 94 4wd 6cyl with 188k on it and think I may have to replace the oil pump and main and rod bearings. It's starting to rattle a little when you first start it up in the morning, and the oil pressure falls to nothing when idling warm. My question, is there enough clearance to remove the oil pan and replace the bearings without pulling the motor? If so, can the rear main bearing be replaced also? there's no leaks so I shouldn't have to replace the rear seal unless I just have to. thanks in advance

 

you have to remove motor mount bolts, fan shroud and jack up the motor.

do an advanced search for oil pan removal for many posts on this subject.

 

Thanks for the info, I did a search, and from what I read , I can replace the bearings except the rear main without pulling the engine
