Struggling here.... down to Timing Chain Cover, but have no idea what an Oil Pickup Line is.....
The write up says may have been removed in step 4, but step 4 is draining coolant?
On a time crunch on this one.. if anyone sees this, please help!

The oil pickup line is shown in the photo below step 6 in the removal post. It's the pipe with the round canister on the end.

Sorry about that, I updated the description to reference step 6 instead of step 4. Thanks for pointing that out!

Unfortunately, I think I may have a timing chain issue in my newly acquired 2007 with about 95K miles. I have attached brief avi files of the engine running cold and warm.
This thread is great and has given me a level of comfort to attack the project myself. Does anyone have thoughts on what else I should consider replacing while I have the cover off? I already plan to do the water pump.
I also know I will need a new oil pan gasket, front cover gasket, new fluids and oil filter.
A reference was made in a reply about two or three Miller special tools. I have searched the web for a description of them and how they function. Not much there other than lots of listings on eBay. Trying to determine whether they are worth looking for. Any help appreciated.

Note: I attempted to attach avi files. I apparently don''t know how.

The only way to determine if your timing chain & gears are out of spec and need replacing is to pull the pan and front cover and measure play on the cam gear. If you've gone this far you might as well replace it. You can pull the pan and check for slack by just observing the amount of it with one side tensioned. At 65k miles or so Mine was loose on last two teeth of the lower gear. Unfortunately I had to drive it another 9,000 miles before I could get to it.
Mopar sells a front cover gasket set that has everything you need, front cover gasket, front seal, upper oil pan gasket and oil pump pickup o-ring. The special tools I used are in the description above. They ensure the crank gear is removed and reinstalled without damage to the crank. If you're mindful of potential damage you can improvise. I felt it cheap insurance to buy the tools. I used a 3 jaw puller to extract the crank gear. I had to grind the jaw teeth a bit for them to fit between the gear and crank. It slowly came off no issue.
End result, it runs better than ever. The chain design is a cheap POS, frankly, and I'm surprised more haven't been done. Be careful but it's worth the effort.
