Re: ticking noise

sounds like a lifter/pushrod.

not much you can do without taking the valve cover off and checking

??? yeah you can... a sticky valve is gonna show up in a vacuum test, and if you wanna tell where the ticking is coming from, take a piece of hose, hold one end to your ear and the other to a valve cover. its like a stethescope but cheaper and just as good. you'll be able to hear exactly where the sound is coming from.
