Hi folks, I have a 1982 2L Spider Veloce that was slightly modified in a rebuild by a previous owner. When it warms up I hear a knock in hte engine that sounds like a valve knocking. This is the first chain driven cam engine I have owned, and the first working Alfa as well, so for a while I thought I was just hearing the chain. At idle the noise noticeably drops and at higher revs I hear it more destinctly and the timing of the noise leads me to bleive it is a valve. So my question is this: Should I check the valve clearances, or is this just a standard Alfa engine noise? If it is a valve noise will the correct shim size fix it, or am I in for an expensive head job?
Thanks,
Bill
