If your engine is a SBO, it's likely that the rear main seal is a 'rope seal' and if so I was wondering how bad it is leaking. Every SBO engine that I've owned that has had the 'rope seal' has been damp around that area. With that said, the area was damp and didn't leave an oil spot on the ground. How bad is yours leaking? If it really needs to be replaced, you should replace the seal before fixing the AC because I'm pretty sure (I could be wrong) the engine will need to be removed to replace the rear main seal. I've never replaced one of those with the engine in the car.. I'm sure that some of the other Olds guys can chime in with regards to the rear main seal replacement on an Olds engine.

AND if you're replacing the rear main seal and it's a 'rope seal' a nice upgrade is a non 'rope seal' if that make sense.

BBO can use a Frod 429-460 rubber rear main, not sure about SBO....

Back years ago when I performed this repair on SBO, I recall utilizing a Felpro BS40612 or a Ford item for the upgrade. Maybe it was the seal for an old Ford 292 engine? The Felpro number is good btw..

You want to convert to R-134a. Thourghly flush system and as I recall a pag oil. After you flush, flush, flush allow 2 ounces in the condenser, 3 in the evaporator and pour 4 in the new accumulator with a new orifice. Make sure you use a good vacuum pump with fresh oil and keep on as long as possible.
