Great post! This is exactly what I need to! My catch can finally arrives this Friday. Hope to take it to a garage to get the same thing done. Hopefully this will calm down the kr knock I've been getting. It has already calmed down some over the past couple of days. Not showing anything higher than 3 or 4 at WOT. Amazing how much some bad gas can cause huge knock increases.
I advise everyone to get a catch can, you should have one on order before you even consider buying this jeep.
I had an issue after my first oil change, my catch can didn't have too much oil in it, maybe 1/4 full at most. I did get an oil leak after the oil change and they had to replace something (don't remember off the top of my head).
Well, I am coming up on oil change 3. Just noticed that I have oil on my garage floor again. Opened the hook, there is oil on the top of my intake. Opened the catch can, it is about 3/4 full, this is from 6000 miles of driving.
Taking the car in tomorrow, my guess is I have the same problem as before, I think it was the oil cooler leaking. This is great, I guess its the price you pay for buying a new model car. I had a 4 runner for 6 years and had not 1 problem, I have already had 4 annoying ones with this jeep in less than a year.

For those with catch cans, they don't catch everything, so it's still worth cleaning manifolds on occasion. It won't be needed as often with the cans, but some oil will go by (at least that's my experience on a few other cars anyhow.
I've had my oil filter leak twice and needed replaced. I'd notice small puddles on the garage floor, sometimes a burning oil smell when driving. Also, looking under the car I could see the oil residue on parts.
