Yesterday my beloved car started making a "tapping" sound, which I suspect is a valve noise, but I wanted some other opinions before I start tearing through the engine and replacing things. I kind of sounds like a lawn mower, sort of muffled beneath the normal engine noise. In listening to various sections of the engine, its hard to tell if its coming from the valve cover area or the exhaust (or somewhere else). Could this be the infamous timing chain tensioner or am I correct in thinking its the valves? Any help would be very much appreciated!

Thanks in advance,


make sure you check your exhaust header studs/nuts. if you're missing 1+ of these, you'll hear a sound very similar to the one you're describing....
