I don't want to derail a 3v head topic, as this is a Mustang forum, but I was curious because many 4v heads produced around the 2001 / 2002 time frame had an odd tick in the heads (mine included). It goes away when warm, which is what was described in this TSB. I've never heard of any rod knock preceeding this issue, and in most cases these 4v heads do it from day 1, right off the factory floor. As with the noise some 3v heads are making, Ford has been claiming it's normal and not to worry.
I actually talked to a former Romeo engine plant employee at the Woodward dream cruise this year (which was awesome, btw) who said he thought it might be related to the tensioners for the chains that drive the over head cams. Anyway, just curious about the 3v head tick as I thought it might be related. Thanks for the feedback!
