1994 4cyl Replacing AC Compressor / Seal on AC manifold?
I replaced the AC compressor on my 1994 4-cyclinder and I went to charge it and I was getting a small leak during the vacuum test and I stopped.
When I connected the new compressor from Rock Auto, the little block with the inlet and outlet tubes seems as the seals are concave and it's metal to metal?
Am I supposed to put other seals here? It doesn't seem as there was a good seal.
The rest of the system was fully charged and did not leak prior to changing the compressor. This is the only spot it can be leaking. Suggestions?

I replaced mine with rock auto parts as well. But I replaced both lines as well they came with new O rings. And a set of extra orings. One line did have a flat edge on some Orings so I replaced those. I'd say if the Orings are mis shaped on the back of the compressor I'd replace them.
As far as the oil leaking from back of compressor. I just tried to keep it tipped up as I bolted the lines to the back of it. If some leaks out just add a lil extra to the evap canister.
Should be 50/50 half the oil goes into compressor and the other half goes to evap can. I also drained the shipping oil out of compressor completely like it said in instructions.
