Re: Front crankshaft seal leak?
I have a front end leak too. It acts like an old VW, it leaks one or two drops everytime I shut it off. Even that is too much for me, so I have been looking into it. Your mechanic is either gouging you or not experienced in the 7.3 PSD. He must think the pan has to come off. The harmonic dampener comes off like any automotive one, has a seal behind it like any automotive one. The oil pump is behind the dampener, and the seal is in the front of the oil pump. There is also an oring between the oil pump and front cover that could be it. I'm not positive my leak is not the oil pan to front cover seal, I havent proved it out yet. Good luck!
