3.6 Pentastar Rattling

Could be the roller lifters on the 3.6. Those are notorious for going bad. If left they take out the camshafts. Unfortunately pretty common on those. Changing the lifters isn't too bad, done it myself. But changing the cams is a new level because of the timing chains. I think they make a tool to hold the phasers in place and allow you to remove the cam.

I didn't know you could change the roller rockers without taking the cams out.

FRT the $20 amazon tools didn't help me any at all. I did it 'wrong' about 20 times until I had one extra hand to hold the chain on the lower sprocket. IMO if it has 100K miles on it and you have it open, id change the 2 big chains and the intermediate chain and tensioners. I didn't bother with the oil pump chain (its very short/pita to get off) and my van had 173K miles on it (I owned it since ~40K)

Total parts was $661 that includes timing chain, full set of engine gaskets, water pump, 8 rockers i didnt use, and trans filter.
