I removed the driverside head and had a machine shop retap the second spark plug, cause it had blown out. When I removed the head I made marks with nailpolish on the chains and gears. I'm working with a 4.6L wep. I never removed the passengerside head, gear or chain at anytime, when I put the head back on I just realigned the chain with the mark on the gear. I reassembled the entire engine and the truck started back up but with knocking noise under the valvecover of the replaced head. Aside from the noise the truck runs perfect, but the noise will not go away and i've tried everything. I finally removed the valvecover and put the engine at tdc. My question is where should the mark on that gear be tdc, cause I can't seem to get a straight answer from a manual I look at. The 4.6L rep says to use a square and the mark should be at a 90 degree from the valve cover plane but nothing for the windsor plant.
have the same problem?
