Last year the 75 started leaking oil and I though that it was a rear main seal. After I found that the motor mounts were bad I started to look real had for the leak. The oil pan was rusty so I took it off and wire brush it and found that it had a rust hole by the dipstick. Replaced the pan and put a 1 piece pan gasket on and now no leaks. the 1 piece makes the job real easy. Unless some one is looking at the pan no one will know it is a 1 piece gasket.
