Just found out that they sell modular brackets to fit this air line filter WIN!


Here is another bracket they sell for this filter. The kind I was wanting to make. Same website http://www.ereplacementparts.com/wal...-p-497609.html

Nice job, I have seen many people add the same thing on the Hemis because they build up oil sludge on the back of the throttle plate. I have not had a problem with my 07 Hemi yet but when I do I'll probably add the same thing. BTW the 4.0 is not really prone to this at all, when I pulled my throttle body to clean it there was a coating on the back of the plate as expected but the intake manifold was really clean for over 140000 miles....

Just ordered this -> Oil Catch Can I'm going to braze some some drilled copper tube on the inside of the top "IN" fitting, add a baffled filter section and lower drain petcock. Basically a copy of this; Modded catch can and its cheap, $35 shipped for the can and maybe another $10 in misc parts. Gotta get rid of the ricer sticker before anything else!

Needs parts?

I opened it up today after a couple days of driving with it and there is already a tiny bit of oil in the bottom so it's doing it's job.

I don't know. 4.0 uses a CCV( closed crank case ventilation) system where as the v8's use a PCV(positive crank case ventilation).

I am pretty sure you can though. Just do a google search for a CCV oil catch can or something like that. I'm not sure if the 4.0's have an issue with oil coming back around into the intake.


Here I found this.

The filter catches the oil droplets that go back into the intake through the vapor. The oil getting into the intake is what causes pinging and gums up the intake and can clog cats and ruin 02 sensors.

Keep an eye on the inside of the suture getting from Home Depot or Lowe's. They were not designed for the type of heat it's coming from the engine bay as well as the vapors coming out of the engine. These were tried a lot of times with great failure in the Corvette community.

Yea I am concerned about that. I am going to make a heat shield for it. I need to get an all metal oil catch. This one is all metal minus the insert.

Real nice set up you made Polka and noticed you even used high priced fuel injector hose.

Guess I don't understand why this XJ owner w/a 4.0 had to put a breather in his line along with the filter bowl?

http://www.jeepforum.com/forum/f46/x...ml#post2481878

In maintaining 4 Jeep w/the 4.0 only my 93 XJ w/235K miles have I seen where oil is coming back from the front valve cover hose and dripping on the air filter. But once I cleared the rear line, installed a new CCV, and cleaned the inside of the valve cover while replacing the gasket the oil quit blowing back. It probably helps I change out my oil at 3,000 miles so the engines don't get gunked up.

This link applies to the 4.0 and explains the oil blow back. It's for a XJ but the same probably applies to all 4.0 models except for the part numbers. The guy incorrectly refers to the rear valve as the PCV instead of the CCV.

Thanks. I have blacked it all out since then. I have the sheet metal to make the heat shield but my Dremmel just took a crap on me. Power cord issue. Should be easy enough to make some tabs and attach a shield to the coolant overflow tank studs.
