My oem compressor was so cold you could hang meat in that buick. But it croaked after 85,000mi. The new one is an eBay one. It does alright but not like oem stuff. The camaro has no a/c cuz some artard ripped the wires of the compressor when they pulled the motor or something. I think it's from a busted motor mount in the past that let the motor torque over so far it ripped em out. All I have is two bare wire studs sicking up from behind the pulley. The are shaped like a posi traction burnout (they curl to one side)
    LOL @ posi traction burnout.

Where should i start? Compression test, cylinder leak down test, pull valve covers check valve train, pull plugs and check for damaged plug? Car runs smooth don't miss but dont want to cause any engine damage. I was planning on installing different cam and maybe some heads. Need to find problem first. Any help would be appreciated. Thanks
    Correct me if I'm wrong, but... according to the laws of measurement and physics... If you bent a piston rod, (which is very hard to do) Wouldn't that make it shorter....
