Re: Oil Catch Can
Several of us with the 5.7 have custom mounted them in different ways. The picture above is how I did mine, and what it looks like with the engine cover on. As you can see the lines go under the cover. Here's a pix with the cover off. Note, you can barely see the PCV valve housing on the intake, on the passenger side, in the back. The valve takes a quarter turn counter clockwise to remove it. The PCV valve for the 5.7's are generally not available at parts places. Most don't even show a listing. The dealer is the best place to get it. I was able to get one from Napa Auto, but it is the Mopar part, not an aftermarket version.
As far as cleaning the throttle body goes, it can be done. Many of us have done it, but it must be done with care, a soft rag or brush, and a mild solvent or rubbing alcohol. Some remove it to clean, but I didn't. Once you've cleaned it, installed and properly maintain the catch can, you should never have to do it again. In about 5 years on my Hemi LX, I've just gotten a very light film that easily wipes off with a soft rag. Do a search and you should find a "how to" on this or one of the other Jeep forums.
