Currently replacing my ac compressor and I’m wondering if the rear lines coming out of the compressor are installed correctly. They don’t look fully seated to me.
When GM changed over to R134a back in the ‘90’s they switched from oring seals to seal washers. Look up the seal washer kits and you will see they are a steel washer with an inner rubber seal. The steelwasher clamps between the block fitting and the compressor to provide a fairly precise amount of compression for the rubber seals.
I did use those, I just noticed that there was a gap that I don't remember there being from another ac job I did on a different c5. Also im having another gap issue where the orfice tube connection is at.
Did you use the correct seals? Did you try and draw vacuum? Gotta give us more info for us to help you
I drew a vacuum and for an hour it held at 29psi about. I let it sit for another 3 hours and came back and the pressure had dropped to 20psi. Gauges may be faulty but I doubt it.
I used similar sized seals included with my rock auto hvac kit I ordered specifically for the c5.

What was the reason why your changing the compressor? U had to keep adding freno? not blowing cold or compressors locked up??
The orifice tube looks fine. Any time you have 1 bolt connecting a junction like that, it will always tighten with a slight angle. Looks normal to me. The compressor I can't tell from pics. If it's the same model compressor as the OEM, and you're using the same bolts, it SHOULD be OK. My compressor has the coated, silver colored bolt. Yours looks black. You could remove the bolt and manifold, screw the bolt back in until it bottoms out, then measure how much space is under the bolt head/washer to the compressor surface it bolts to. Then measure the combined thickness of the gasket and manifold. This would tell you if the bolt is too long, and is bottoming out before it tightens up. Best of luck..

If you suspect the bolt is too long and there is clearance, put a washer under the bolt head and see if that closes the gap further.
