Re: PCV line / Oil Catch can

Well, no CEL with the elbow installed. I will hook up the Provent and remove the filter and expect the same progress. Glad to know my lines are fine. I think that Provent filter is just too restrictive for US diesels PCV sensors. I may have to keep the filter removed and just stuff it will metal mesh. Won't be as efficient at capturing oil, but it's really my only option.

Re: PCV line / Oil Catch can

Yes, it's the filter element. The lines were never the issue. I replaced the filter with a stack of mesh copper sponges to collect the oil, no more CEL's. After about a 2,000 mile drive, I had about a half cup of oil collected.

I don't think the metal/mesh type catch cans (most types) are as efficient as a paper element, but that paper element is just too restrictive for US JGCD emissions systems. I'd rather have something catching some oil than nothing as before I even installed the catch can I could see/feel ton's of oil in the intake tract.

I don't imagine the engine "needs" the exhaust gas recycling, but rather that it's the EPA forcing the issue. Concordantly, I wonder if the sensor can be defeated, thereby allowing one to use the paper filter element in the ProVent despite the increased pressure drop it induces.

Anyone have an idea of how involved it might be to mock out the sensor with a dummy?

Re: PCV line / Oil Catch can

the healthiest thing for the engine would be to block off the hose connection on the intake and run an open hose from the engine crankcase vent to somewhere below and behind the engine so that the HVAC system will not suck up the oil smell when idling.

Wouldn't it be even healthier for the engine to hollow out the DPF and reflash the PCM to not require the DPF to be present/regen? I imagine that running the crankcase vent into the hollowed-out DPF might be a convenient option.

That's fairly major though, and the PCM would still need to be flashed or the PCV sensor replaced with a dummy in order to avoid throwing emissions codes for the disconnected PCV line.

Yeah... and we could fuel it with baby seal blubber, extracted with CFCs

Re: PCV line / Oil Catch can

i do not have a jeep yet, but have talked the wife out of a gl350 or a range rover sport supercharged, and into a summit thank goodness.

i have been trying to find exploded diagrams of the VM motor showing all of the parts to see how everything works. in my 2008 ram 6.7L, i have it running beautifully. i was getting 14mpg average stock, but now i am able to get about 16 city and 19.5 hwy @ 80mph (this is with 315 size tires too!).

as far as the CCV goes, all it will do is throw oil vapor into the turbo, coating the compressor wheel and everything else in the intake piping. once i get the vehicle, the first thing will be to vent to atmosphere.

i think there will be some great gains to be had from removing the DPF, but that will be for another day. mabe if i get super bored i will be able to find out what voltages that the O2 and temp sensors are looking for and get some sims made up so that they can all be fooled. really not looking to go down the tuner route as it should not be necessary with the right equipment.

Re: PCV line / Oil Catch can

How do you plan to deal with the CEL? Just leave it on?

the side of the CCV line after the PCV is always at atmospheric pressure or below. leaving the PCV intact and venting to atmosphere should not throw any codes. from my experience, added restriction (pressure) is what will upset the computer.

Milous was kind enough to post the Chrysler VM 3.0 student guide in a thread. You need to be a premium member to get to it.

Should we be concerned with sludge and moisture build-up as a result of not enough negative pressure? Road-draft tubes didn't do a great job getting all the moisture and fumes out of the crankcase, especially at vehicle rest.
