Oil Catch Can
Can you put a oil catch can on the 4.7 are is that just for the bigger 5.7 & 6.1 engines? & will it do the 4.7 any good? I have asked a few ppl. & nobody can give me an answer. Everybody i talk to says good question. So can somebody give me an answer? Thanks for any info.

Re: Oil Catch Can
As far as I'm aware, you can fit one. I believe the Hemi's tend to have more of a need for one.

I'm planning on fitting on to my 4.7 soon.

Re: Oil Catch Can
You can put a catch can on anything that has a Positive Crankcase Ventilation (PCV) system....I believe everything today has it. They do work, especially in the winter months, and you'll also catch more at higher speeds. I just got back from an 800 mile trip with my 5.7. Before I left I had changed the oil/filter and emptied the catch can. Upon return, oil level had not changed (still full), but I had about 4 oz. of water/oil mix (mayonaise) in the catch can. Without the catch can this crap is cycled into the intake manifold and through the combustion process. It makes a mess of the intake runners and the back side of the throttle body gets caked with crap. Check yours, with the engine off, by removing the intake tube at the throttle body and manually opening the throttle butterfly. Look at the back of the butterfly and shine a light into the runner area of the manifold, if you can. On the 5.7's some will even see puddling of this crap in the manifold, and I'll guarantee that the back of the butterfly will be crapped up. I've had catch cans on my Hemi WK since I bought it ~12,000 miles ago and on my Hemi LX for about 5 years. I will not go without one on any future vehicle either.

Re: Oil Catch Can
Where do you get a catch can? Any better than others? Also I have a 138k miles.... would it be pointless to install one now?

Good question I'm interested as well

Re: Oil Catch Can
Billet tech do nice ones. But you can pick them up all over. I'm sitting at 117,000 miles and fitting one next month.

Re: Oil Catch Can
Diablosport and Billet Tech are the two name brands that come to mind. I have the Billet Tech and I am very happy with it. Great quality. Get the braided hoses with it.

I concur....Billet Tech. is about the best out there. They can be adapted to most applications if you can't find one for your exact model. The one for my WK is for an LX hemi, since when I bought mine they didn't offer one for the WK. I would think that the higher the mileage, the more need for it, as the PCV valve will certainly be passing more by-products through it. Also, make sure your PCV valve is well maintained and replaced as needed/required. If there is any doubt in your mind, I would recommend that you check behind the throttle butterfly on the throtte body, as I indicated in my post above. If it's all crapped up, IMO, you need one.

Re: Oil Catch Can
I did notice that my TB was very dirty. I also read that it was bad to try to clean it out (ruins the sensors or something like that). I'll be getting the Catch can in the very near future! Also have to try to figure out how to replace the PvC valve last time I went to the parts store, they told me I don't have one! lol

Re: Oil Catch Can
Also does the billietech can work with the hemi engine cover? do they have a bracket that will work or do you have to custom fab something?
