So originally the owner was asking 4K for because he thought the rear main was leaking and did not want to deal with it but here never mentioned that to me on the phone.
I get there and check the usual pre start stuff and then start it up sounds fine Goes into gears fine test drives fine. He tells me there is 1 problem and it's the rear main seal is leaking. I look underneath and i was pretty sure the oil cooler line was leaking not the rear main. So i offered him $2500 and he took it.
Changed out the original gm seal this morning and the only thing i could get my hands on was a FelPro one.
Start it up and it leaks worse than before!
I have a real GM one on order. Pics show the difference. Gm then FelPro.
