Topic: PCV and my problem with it...

[Sol Asylum]

I have to respectfully disagree with our English delegate TS.  The manual says that the cam cover bolts are 89 lb in (10 Nm) not 89 foot pounds.

Tomato got the intake one right so he's at 50%, GJ put him on double secret probation and lets hope he gets his act together.

[Critterman]

89 sound high, where did you get the info TS?

[TomatoSoup]

OK, my bad.  I misread it.  It IS 89 lb.in. for the cam cover.

<Sorry>

How dare you?



Just kidding.
Thank`s for your help, I`m starting to really look forward to the weekend, can`t wait to install the stuff.

[Sly Bob]

Waiting for SlyBob here... he powder coated his turbo shield, though with hi-temp stuff I believe.  Bob?, still OK?

Sorry i hadn't seen this earlier, I don't read ALL the threads.      Six months old but here goes.

As of early last year I have a different powdercoater as the last guy decided to get out of the business. The turbo cover was done in a wrinkle black hi temp powder and it still looks as good as the day I got it back. I was told it's the same powder he uses on wood stoves so it should hold up, it did.

[Napi]

Damn.

I finished the install a month ago, just forgot to post the results...

So: I am done.

This is what it looks like:





I am using the former "PCV" chamber in the manifold for my boost sensor, this is why I did not remove the "arm" although is it sealed...

Interestingly, the Catch Can catches about 400ml of residue every 1000km driven... More than I expected...
I will keep you updated.

It looks like you're using the Provent 200. So, the oil return from the Provent is going to the OCC?

Exactly. I installed a small (750ml) OCC right next to the battery and added a drain with a small hose ending in a simple valve below the fender. So I am able to empty the occ without removing the Provent. Because I am lazy.

I read up on the Provent 200 and it says it's only good for cars up to 335HP. Do you think the Provent 400 is a better fit? I will probably delete the OCC and have the return line go to the oil drain pan.

I had the exact same thought/fear but contacted the manufacturer. They told me the 335hp is just a rough guess, heavily depending on the engine type. With a "small" 4-cylinder, 2.0litre engine the Provent 200 should be able to handle way more then 335hp. In addition, the size of the 400 may be a small problem, the 200 fits just perfectly, with the hood closed there is less than one centimeter space to the hood while the drain is just about 5mm atop the battery.

I will probably delete the OCC and have the return line go to the oil drain pan.

Also one of my early thoughts, but the liquid caught is at least two thirds (condensed) water, even with the occ attached the engine had no visible oil consumption on ~3.000km.

[Helios]

Ok. Good info.

The 2.4L supercharged guys, like me, are experiencing a problem like what you have. The PCV pressure plate in the intake manifold just isn't cutting it. I thought I had a solution, by blocking off the PCV pressure plate and adding 2 in-line PCV valves (one on the OCC and one on the return line to the intake manifold). However, it's now blowing the dipstick out. So, I know I'm not relieving enough pressure from the valve cover. I ordered a MBR0003-10AN valve cover adapter ( http://www.metcomotorsports.com/proddetail.asp?prod=MBR0003-10AN ) to go in place of the oil filler cap to run another line to the OCC. It should come in the mail today. I'm still not sure that DDM's OCC is doing a good enough job at separating the oil or perhaps I'm not getting enough vacuum from the fitting I put on the intake mani.

[Napi]

Uhmmm.
You said you installed two additional valves while blocking the internal valve inside of the manifold, correct?
But you kept the valve mounted on the lower intake tube, also correct?
Where did you install the valves?!
My ProVent is installed without any valves between the valve cover and the turbo housing. The only valve I used is used to seal the catch can below the ProVent. I only use it to release the "caught" liquid when the engine is not running and the top lid of the ProVent is open...

[Helios]

I did this mod on a 2.4. So, it's a little different than what you've done. I'll have to take pictures of the current setup and post them. I just ordered a Provent 200 as well. I'll end up connecting it to DDM's OCC instead of recirculating the oil back into the system. I hope this really fixes all the oil I was getting into the intercooler, charge pipes, and quits blowing the dipstick.

[Sol Asylum]

... and quits blowing the dipstick.

Hey GJ I think there's a joke to be made here, maybe include Gwyneth and conscious uncoupling.

Who are you calling a dipstick?

If you have to ask...

Nicely done TMZ-SA

Napi, what did you use to reduce the size of the hose from the Provent to what is installed on the valve cover? The Provent 200 inlet/ outlets are 1" ID while the valve cover and intake manifold barbs are 1/2". Did you just squeeze them down tight with clamps? I also cannot find a hose large enough to fit the Provent at the local car stores or Lowes/ Home Depot. The largest I can find is 3/4" ID. Where did you source all of your material from?

I found that the MBR0003-10AN valve cover adapter and the PRE-21090BLK -10 AN 90 Degree Push Lock Swivel Hose End Fitting Black (http://www.ebay.com/itm/230951042242?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649) that I ordered is too tall and will not allow the hood to close. So, now I'm wondering if I need to get a larger fitting welded onto the valve cover to relieve enough pressure/ gas to flow through the Provent.

I also blocked off my PCV plate to make sure oil didn't make it's way back into the intake as shown here.

Hello!

I removed the original connector on the valve cover and welded an aluminium dash-connector onto it. I also drilled a hole into the cover and welded a second connector onto that place. Then, I used 1/2" (I.D.) hoses (heat resistant up to 135 Celsius but I added an heatshield-tubing made of cevlar or sth) to connect these connectors with a T-style connector (1/2" - 1/2" - 1") placed next to the charge tube. The T is then cirectly connected to the ProVent using a 1" hose. And finally, another 1" hose connects the ProVent to the turbo housing using a custom made connector.
