On my 2002 4.6 - 141,000 miles I have a really harsh metallic tapping coming from the back of the engine..... at idle and fades as RPM increase.... seemed to come from the drivers side, rear top of engine....
I popped the valve cover off and had a bad timing chain ( had eaten thru the guide and chain was eating thru the tensioner piston) Did not think this was making the noise - but had to replace all parts on both sides....as it was ready to grenade...
I thought the knocking/tapping might be a lifter- so while I was in there doing the chains - I put a set of OEM Ford lifters on the whole drivers side head....so 8 lifters....
Still had knock....
Now I just noticed - if I put step on the brake and apply throttle the knocking stops..... so is this a flex plate cracked or loose.... or a torque converter issue.... or engine knock... what metallic knock would disappear when you put the drive train under load.....?
Noise seems more on drivers side, maybe this is coming from the front of the transmission and tricked me into believing it was a head issue.....
