The PCV valve is useful even if you dont have to pass emissions. Using the valve to re-route the oily air either though a catch can or into the intake keeps the engine cleaner. There has to be a restriction in the system or blow-by. can you block both ends and put a pressure gauge on it, see how many inches of water its building.

Where is the oil at that you're saying is chocolate-like? i know you said its coming out of the drivers side of the valve cover, but is it going into a catch can, or an intake, or vented to atmosphere?

Give us a picture of how you're PCV is done up.


Ok here is my $0.02, for what its worth...
Every year.... every year... around this time when the weather starts turning cold, i see posts from all different vehicle owners about discolored oil in places on the top end of their motors... inside oil cap, in catch cans etc etc. and it almost always is simply condensation from the cold weather and hot engine. and Absolutely nothing to worry about.... This may very well be your "issue."

Furthermore, to the question about whether or not you even need to run a PCV... the question is more so, how much do you like the environment. Many cars from the days of old vented to atmosphere or dripped to the road. My car has been setup this way for years.... Is it recommended?... no. Does it work? sure. In fact i'm currently working on a way to vent even more to the atmosphere... haha. There is some proof that more power can be had from a vacuum being placed on the valve cover vent, but I'd rather keep the oil away from my turbo inlet, or my intake manifold. And catch cans only serve to catch the oil i can just let drip on the road..... im a bad environmentalist.

Thank you this is what I was looking for. The chocolate oil is pushed out of vent on the driver side valve cover. I have a hose attached to it with a filter on the end of it. Nothing really comes out of the catch can and if it does it’s usually a little bit of water. Well what looks to be water. I’ll post a picture of my set up here shortly

I dont get any oil in my intake tube and the picture I posted IS my setup. So, im not sure why the pressure is building to the point that it escapes through that route vice through the PCV tube, unless that end is less restrictive.

I guess one thing that may help is to ask just how much oil we are talking about? The way you made it sound I was thinking it was gushing out, like would fill a cup in short order.

I think these are valid questions but I'm of the opinion that that much hasn't left my breather in the life of the vehicle.

That volume is disconcerting and probably not weather related.

here is my set of. The puddle is gas from my catch can. Watered down gas it seems,the last picture is where the oil is coming out at, the filter at the end ofthe line. It’s about 1-2 days of driving around town

when is the last time you changed the breather filter? if it is clogged full of oil, you will be making your problem worse.

the reason why the OEM setup was PCV to Intake manifold and also right side (breather) port to the factory air box was to keep the crank case constantly in vacuum as the car was running, removing gases from the crank case to be re-consumed and burned by the engine during operation. In vac, the motor pulls these gases through the intake manifold line directly to the head and valves. When in boost, vacuum is created on the inlet side of the turbo accomplishing the same goal.

This is why many will recommend two catch cans if you are concerned about too much oil making its way into your intercooler or just running a line directly to your aftermarket intake in the manner it was designed. So long as your PCV is working properly, you shouldn't ever really end up with much in your catch can.

When your breather is clogged and not flowing not only will your engine have to work harder to evacuate the gases in the crank case, but much more fluid will end up in your catch cans and not be consumed by the motor. I think that the watery gas you're seeing is potentially some worn rings that aren't seating well until warm and allowing some fuel vapors to mix with oil vapors and condensation in the catch can you have. I would recommend picking up a cheap catch can (or follow a how-to on here on how to make one yourself) and hook that right sided line back to your air intake and see if you notice a reduction in what the tanks are catching.

Also a leak down and compression test couldn't hurt.

Thanks you. Any ideas as to how I can run that into my intake? And despite all the aftermarket work, would going back to stock with the pvc system help?

I think the issues your being caused stem either your PVC or rings. I'd try to rule out both before doing any work though. Compression test would be a simple way to start. Another member mentioned a way to test the PVC.

like was mentioned before, is your valve cover an 05 (screw in PCV) if so may be worth getting the correct PCV and eliminating any extra complexity there.

as far as your intake, you could find a coupling with a nipple on it or on the cheap you could drill a hole and thread in a nipple. any parts site should sell them as well as cheap catch cans.

do you have access to a compression tester? get/borrow one, read up on, and complete a compression and leak down test to rule out internal issues and report back your findings.
