Replacing the Timing Chain on 2006 Jeep Commander 3.7l v6

Hello everyone! I have a 2006 Jeep Commander v6 with 190,000 miles on it. I have replaced a few things along the way but for the most part it has given me very little trouble. I do have a fairly major oil leak coming from the timing cover though but have just been adding oil throughout the month. I recently had a rattling noise coming from the engine and took it to the shop to get it diagnosed. They say it is coming from behind the timing cover and that it needs to be checked out. So I am currently in the process of changing the timing chain and am wondering if any of you have done this before? I do most of the work on this vehicle myself so I am familiar with everything and it hasn't been too bad so far. I have removed the A/C Compressor, Alternator, Fan/Fan shroud, Tensioner, and Battery so far as well as a few other little things. Still need to take of the cylinder head covers?? and the power steering pump. Any comments on all this would be great!

Alright so finally finished this repair. Everything checks out and it runs beautifully. Was certainly not an easy repair. But saved about $1000 dollars and learned a lot. The timing components were in terrible condition to say the least. Turns out 190,000 miles on the vehicle causes a lot of wear. The sound coming from the engine was caused by a few broken off parts. Needless to say, the sound is gone and it runs great and very quiet. Would be happy to answer anyone's questions if you are thinking about doing this! Pictures to follow. Before and afters should be obvious. Also, changed valve cover gaskets and grommets and a few other gaskets and obviously the timing cover seal. Changed the oil and decided to go with synthetic and an oil stabilizer. So far so good on that and should be beneficial.
