I have a compression tester I can fiddle with next week. although im strapped for cash til the first. so replacing plugs and coil packs are going to have to wait, ill keep the forum updated. I will try and pull the plugs and see how they look. Ive heard if you pressurize the cyl with compressed air you should hear it hissing if there was a leak. the piston in question must be at tdc and listen for hisses through the oil fill for leaks in the rings, hiss in the tail pipe for an exhause valve, hiss in the throttle body if its an intake valve and hiss in the rad if its a head gasket issue. and you can use a compression tester hose to pressurize the cyl but you must remove the shrader valve from the tip so it can flow air. im going to play with this next week.
this is a link to a youtube video of the sound in action its pretty prominent. let me know what you guys think.
