Pardon me if this is covered alot but I couldn't find an answer by searching. I have a 97 250HD 7.3 with 253k on the clock I bought it with 230k. When I bought the truck the seal between the HPOP and the front cover was leaking pretty bad. Last summer the HPOP went out on vacation and a Shop in Springfield MO put a new one on for me and it still leaked just as bad after they put on the new one. Well last night the seal finally went all the way and oil was just pouring out. Any reasons why this seal would have still leaked after they replaced it? Couple things: the bolts weren't stripped or loose, the pump, front cover, and gasket all appeared good.
there is something strange goin on here , maybe one time in 15 years have i seen that gasket leak, they just dont give problems , and for you to have a repeat repair for it , are you sure the gasket ois where the problem is
