Where did anyone say the chain was hitting the cover? Like to see a picture of that cover to confirm.

It wasnt hitting the cover it was hitting a screw from the oil pump cover plate which had backed out. The chain deflection was also more than allowed so I swapped it out since I was in there fixing the pump cover. The tapping/
knocking from chain hitting the screw has obviously now gone. But my engine still sounds like shit! Yes its a chrysler 3.8 and its noisy.......but thats no reason to ignore what could be a simple fix.

This whole story sure doesn't sound like anything any other 3.8 engine owner can expect to happen.
2 weeks to get the chain in the first place says how often the engine ever needs one.
Come on...what's really going on here?
You are in Toronto and the main Chrysler parts wharehouse for Canada is in Brampton which is the suburb on the north end of the city.

Like I said chain was out of spec. Maybe thats why the oil pump cover screw backed out...who knows. It was making a horrible noise . So...
Yes the chain did need replacing.
Yes the oil pump did need rebuilding.
Chrysler did not have the parts available in the local warehouse and due to it being Christmas and New years I had to wait 12 days.
Did I fix the timing chain noise? Yes I did.
But! There is a deep knocking noise resonating from the lower oil pan that gets loud once the engines hot. I drive it 3 or 4 times a week. If the motor blows so be it. But if I can be proactive and help it out I will. I have the time ,I got the tools and I enjoy working on the jeep.

Dredging this old chestnut back up. OP, did you ever find the source of the bottom end noise? I replaced the upper oil pan gasket on my '09 last weekend and discovered the timing chain had WAY too much slack. I could move the slacked (driver) side about 1/2"+ With no parts or time to fix it I buttoned it back up. I'm getting kind of a raspy, racket at certain RPMs (2000, 2700, etc.) under load that I was pretty sure being caused by the timing chain. Now that I know this I have to fix it or it'll drive me nuts.
did you go for the chain replacement? I have to replace my upper gasket in next few weeks (leaking bad) and have similar noise - erratic clatter under load at those RPM’s.
sorry to revive!

The OP of the writeup did a splendid job, I just added a few thoughts. I purchased a couple of the Chrysler special tools (8450-1 & 8452) which made the crankshaft gear, front crank seal and harmonic balancer installations go very easily. Also, you'll need the little paper spacer that goes on the cam position sensor for it's installation. The part# is 5552229AB.
