I just did a set of exhaust gaskets on a 24K mile car. I'd bet money that's what you're hearing. The gaskets generally burn thru underneath (there is a ridiculously thin area). Like Andy, I've never heard one where the ticking was really valve noise. The best way to tell is adjust the valves, then when it still ticks, yank the engine and change the gaskets. It's a miserable job, and it is possible to do with the engine in the car if you are really living right. Unfortunately the studs often break, and there are several of them that you can't hit with a drill with the engine in place. Second best way is to notice whether or not there is more noise under load as opposed to at idle - if so it's definitely the gaskets. Dave --------------------- I am fairly confidant its a valve tick. I have looked at the exhaust and it appears ok, the sound is definately coming from the valve cover. Is there a way to tell for sure? The ODO says 37,000 miles (unconfirmed). I think a more accurate assessment would be around 60,000 as the angle drive was shot when I got the car. Dont think it would be much more than that, the engine is super strong.
