So heres the situation, i recently bought a 1990 GT, and the heads were previously warped. I guess he blew a head gasket and they got a little 'warm' and warped. So he had the heads milled .40" over, installed the heads himself. Now, when you let off the gas around 1500-2500 rpm there is a very audible knock, not a slight knock, very knotciable. WOuld this have to do with the valve lash? one cylinder being WAY out of spec and resulting in this horrid noise? or could it be a bent pushroad? im gonna tear into it later today, just asking for some things to look out for. Thxs!
Oh yea, if it matter it has a E303 cam.
