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.

Are you sure the noise isn't coming from a tensionier? Here are the pictures I was able to find regarding the timing:

After waking up the next day and I reread the chapter on timing and figured out what I did wrong. The book I bought at autozone, was refering to the engine as left and right. But after reading it again I figured out that the driverside was the left and passengerside was the right. I removed the cover and moved the cam gear counterclockwise one tooth and wala it started up with no knocking and thank god no damage. Thank you again for all your help and effort, and for being here for us need a little help. May your car be a classic one day.

That is a very easy mistake. Left and right is determined as if you are in the vehicle looking out the windshield.

I'm glad you got it fixed. Take care and let us know if you have questions in the future.
