So I bought a wrecked '02 SVT a while ago and have been rebuilding it. Now that I have her running and everything I am hearing a heavy tick and Im not sure what it is. It isnt coming from the motor. It sounds like the AC compressor. Would it be making that tick noise if there wasnt anything in the AC system? I dont have the air going or anything. I had to pretty much replace the whole front end, radiator, AC system. Any thoughts? Thanks guys.
