If it's jumped a tooth or two, it will certainly make those kinds of noises. If you're lucky, you've only had a little valve contact, and resetting the belt will fix things. Check your cam timing before you drive it again. bs -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
