1LE PCV Oil Separator Kit

[SC2150]

This is even better than the separator GM installes on the ZL1, and as for temps, I suspect it is from their legal dept as with all things releases.

This will be effective on the cleanside for sure, but that is responsible for only 2-4% or so of the oil ingestion....the dirty side is where almost all comes from, but use this w/a good catchcan and you have a good combo.

At least GM is doing something about it.

I won't use at all. Just my RX....but come to think of it.....looks like I might need to buy a normal oil cap

Thanks Tracy, both it is then.

Can you explain what you mean with clean and dirty sides? Also, how would you set up a catch can with this combo and the other pipe plugrd off?

The oil cap will come with the car since this standard part will probably come in your trunk.

You have to poke around the forum. The catch can subject is covered extensively. And SC2150 is at the forefront of the technology.

Tx for that link, read that already and many more. I still dont undrerstand why the 1le seperator is only catching 2-4% blow by because it is from the claen side?

Not what I meant. (And I said legal reasons. ) water vapor will also play a part, albeit small...and while oil won't freeze, it does thicken...and the vapors could condense and pool in the low-areas of the tube. I just suggested the effects cold weather could have on this system that they might want to legally stay away from.

Is this a design flaw with the LS3 engine that you need a catch can or do all engines need this when road racing? (mustang 5.0 ? )

You don't 'need' one for the engine to operate properly during the warranty period. But many enthusiasts swear by a catch can for maintaining performance as the engine accumulates more miles, as you can read in the numerous threads on the subject we have around here.

All modern engines from the factory have a PCV emissions system that sends excess oil vapor from the crank case into the intake for burning. Each ingests oil in this way to varying degrees. It's not a design "flaw" as it is a design variation.

I figured that was what you really meant, but you know how some folks on here are, they take everything literal, so the next thing you may have seen posted was "oh no do I need to worry about my engine freezing" now most C5 member know better but there are allot of folks that come here for valuable info, so I just wanted to make sure the record was straight. Now you are totally correct that oil does get thicker or for correctness increases it's viscosity. The of course, effects all cars and is more of a concern of the oil pump and bottom end damage. This is not of as much concern now days with modern oil, but owners should always refer to the owners manual. In any case people in extreme cold climates should know the effect and cause on oil. But for those that were not as much aware should now be. Great discussion!

Ok, so I finally figured out all the clean side, dirty side etc.

Currently, there is a small (3-4'' long) pipe that goes from under the throttle body (right after the throttle body) which is an inlet from the crank case, to the intake manifold right after the throttle (right above the inlet. This is the dirty side blow by, which makes sense since you are literally venting from where all the action is taking place RIGHT into the manifold. Hence, also why the catch can install is using this inlet and outlet.

The clean side is venting from the valve cover into the intake itself, prior to hitting the throttle body. This 1LE PCV kit is only going to change the vent cover routing, not the one after the throttle that is right from the crank case to the intake.

Hence, I see why above it was mentioned that doing both would help the most. Now I am curious why GM only decided on doing the valve cover change? It would almost indicate that this is the source for most of the blow by and by reducing it there you make the most impact.

Which is why Lexus kicked Mercedes ass with the LS400 in 1989. Base price was $35K. S-Class was $76K. The overengineered overlycomplicated Mercedes sales ground to a halt until they became much cheaper.
