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!
