1LE comes with oil catch can?!?

[FINALLYSATISFIED]

Well apparently the dealership installed mine as part of the PDI inspection. Oh well. I won't lose sleep over it but do wonder how to uninstall it...

We in the diesel world call it a pcv reroute. There is no catch can. There is a hose zip tied to the frame which "dispenses" the unwanted matter.

I don't have a lot of miles on my car and I have been runing with the OEM PCV seperator since day one. The RX catch can doesn't have any dark oil in it, still dripping WD40 (I used up a full can to wash it out).

I have about 1100 miles on the car so no oil in it yet.

The instructions say not to use the oil separator can below 36 degrees. Aren't you in the cold!

I am in the cold and am sure that disclaimer has to do with people not racing in weather under 36 degrees. Do you know how expensive it can be to validate and test a car in the winter because of $5-10 plastic part? Sure as heck cheaper to print a piece of paper, especially since at 36 degrees you will not put very high lat g's causing oil loss through PCV system.... a normal cap suffices in those instances.

Finally, do you think this part is exposed to 36 degrees after a minute or two under a hood, mounted to a big V8? I didn't think of that before..... Either way, I don't plan on winter driving and would've changed it over if I did use it during extreme colds.

Car is garaged for winter :(

Thanks. I seem to recall you had a post somewhere about the RX Catch Can installation WITH the Chevy Performance supplied Oil Separator can. Do you recall where that posting is? I'd like to re-read it.

Yeah, I never ran a catch can on a car before so instead of debating if the OEM PCV seperator works or not I decided to throw both on and if I don't catch any oil in the Catch Can than I can be certain it works pretty good.

Like I said, my previous car had a lot of oil in the intake and I wasn't a fan of that.

That is true with any breather except the RX breather. The RX breather only allows a controlled flow of filtered make up air and keeps the system closed, it does not vent to the air.

And todays diesels do not vent to the air either, the system is closed but a diesel runs at several times the CR and is cpmpression ignition, not spark and ignition timing so the oil ingestion is an entire different issue. Also, any diesel with an open hose will suck in any dirt,dust,water from the ground if the crankcase pressure does not exceed the dirty side recirculation system.

Adding any open, uncontrolled breather allows in an excess of air not metered by the MAF and the MAF, MAP, and upstream O2's are sending data to the PCM that does not fit into the parameters it expects to see, so it throws fuel and pulls it away (log and watch short term and long term fuel trims to see). The RX breathers are all calibrated for the flow that the PCM can still adapt to. Different for a 4 cyl, a 6 cyl, a V8, a V10, etc.

Most dont know this and lump all breathers into the same group (ask any tuner that has to try and compensate for an open breather).

This separator that the 1LE comes with is ONLY for the cleanside and that is generally only a 1-3% of the oil ingestion issue. GM does nothing for the dirty side (95-99%plus of the ingestion), but this is an EXCELLENT solution for the cleanside and eliminates the need for the RX breather kit.

Use this with the RX catchcan and you have one of the best solutions you could at present.

Just like the ZL1/ZR1/CTS-V have (look on the inside radius of the intake coupler...it is a small canister) a very effective clean side separator from 2012 on standard, so no breather kit is needed (would like the sales, but no reason to spend $ where it isnt needed).

Dont expect any solution for the dirtyside from any but the super car manufacturers any time soon.

So what your saying is the RX catch can with the GM Oil sep kit, would be most beneficial in our 1LEs?

Yes. That's what he's saying.

So, Mgizzle above said:

Any risk of doing this? Which port (upper or lower) do you squirt the WD-40 into?

Thanks.

[Mgizzle]

The amount of WD 40 in my can is measured in drops. I of course drained as much as I could prior to installing it, left the bottom valve open overnight with the can upright to drip as much as possible. Some probably still left over on the mesh etc. so once I installed it the air flow pushed more of it off the mesh and into the bottom of the can. It's just like having engine oil sitting in the can, which the can is designed to hold a lot more off. No risk or issues with the WD 40 in there.

As far as clean side being 1-3% contributer, I am not buying that from a "gut feel". 1-3% is insignificant and useless, and I am not sure that GM would go through so much trouble with such a large part for 1-3%.

Again, this is why I installed both because after a while the amount of oil in the dirty side (RX) can will tell me how well that PCV seperator works.

[SC2150]

You just have to pull your intake air tube and coupler off and look at where the cleanside hose attches to see how much oil is ingested from there....very little, and many none. Remember, I have been doing this for over 38 years and deal with this R&D daily, but look for yourself.

RX catch can works!!!
