[QUOTE="tallfreak, post: 14714037, member: 70717"] Your test isn't telling you much. Go to autozone and rent a real leakdown tester. It will tell you how much leakdown you have in percentage. No engine holds air 100%. It shouldn't be coming out of the valves though. I would suspect the back of the valves are a little dirty or even have some surface rust. See if autozone has a bore scope so you can look down in the cylinders and you should be able to get a good look at the valve seat. A single grain of sand will cause a massive valve leak. Junkyard engines in my experience aren't out of time. It's usually a running engine that was totaled. Have you seen the car it came out of? [/QUOTE]
