The only seal I can find is the orange silicone elring. It's supposed to be
the best, don't know if it's double lipped it might be.  Got their full
gasket set as well. To be honest I don't recall what I installed in 97. I
even got the two gland nut sockets and the best seal installer is a 3 piece
set so it stops so the seal is driven in straight and the proper depth. I
just can't bring myself to pull the engine because of the fuel injection. I
just wanted to be prepared. I think it's also leaking a bit by the oil
cooler seals yet most of the leak is the rear main seal. So far it's been
leaking for a long time and has not become worse so I just check and add
oil . The little driving I normally do at most 400 miles per year in a
month I may lose 4 oz.
