i dont have the experience that some of the folks do, started collecting these older diesels about 3 years ago,so anything i say has been learned thru my personal experience.
tell you one thing for sure, you would have to hold a gun to my head before i would move a 3.5 engine without knowing that the oil pump didnt have lose washers from the hold down bolts fastening the oil baffel plates to the block. i say this because i have two 1991 350sdl cars and they both had destroyed engines when i bought them that the 10 cent washer had locked the oil pump. cars had about 208k and 280k,i think they come lose from vibration so how could one predict this failure?
if you are going to keep the car,wouldnt it be wise to pull the oil pan and secure these bolts with red locktite?
