"One other problem we are seeing more as the cars age is the bowing of the manifold assy from overtorqing the single attaching bolt. This makes resealing impossible."
That's my problem.
The upper manifold hose is new, but the rest are original. I will replace the rest of them now. The current compressor (3 years old) came with the Orings and a note they should be used instead of the ones for the stepped. (What should I use on the Orings. Since I am going to replace the hoses, what would you guess the oil charge should be. If I remember 8oz is for an empty system, so I was thinking about 6oz since I am not removing the compressor. What do you think?
By the way, I used the tips on the transmissions on your site for my old rough shifting clunker, smooth as silk now. Thanks
