Actually, probably not. The PCV is a flow restriction with the valve in there, but if it flows well enough, then no reason to drill it out.

 

^is the valve the L shaped plastic at the end of the hose? or is it the one on the valve cover?

the car is blowing oil like there is no tomorrow.. in 3 weeks time, my dip stick reads half way.

 

It's in the valve cover. A catch can that has a mesh and then routes out to a breather will really let you identify how much oil is being blown out and keep your engine bay looking clean.

 

^i have a catch can installed now, and the other end of it is a breather. but guess what? oil is blowing off the breather!! dunno what's happening.

 

The other end of the catch can has a breather? Or the driver's side port on the valve cover has a breather? Or both? A catch can is not working well if it allows that much oil spray out the breather element.

 

driver side pcv hose is connected to inlet of the cc, and then outlet of cc to breather.

 

Well I guess your catch can isn't trapping much oil vapor. What is on the passenger side? Another catch-can breather?

 

didn't do anything on the passenger side..

catch can i'm running is Greddy, i thought the design was fine.

 

Apart from the ARC, is there any OCC designed specially for the DE engines?

 

The Greddy is just an open container - it let's most of the oil through - as you have proven for yourself! I have a Greddy, but I used some jb weld and baffled it and then stuffed it with a sponge that I change on each oil change.

 

i'd very much appreciate if you can post pics of your can (if you still have it).
thanks

 

my mechanic says pistons are gone since it's spitting so much oil and smokes too much.

so i'm going with internals now.. time to build!

 

Help! I thought my smoking issue was fixed, but it's not. I have a breather on the drivers side valve cover and I have a breather on the pcv. Even tried taking out the pcv and it still smokes. Next step is to run what sp was running, but I don't see how the minimal vacuum from the intake pipe will make a difference. From what I gather is that even with the breathers, pressure is building up in the crankcase and seeping up, past the rings, combusting and coming out the exhaust. Am I missing something? Btw, I have a JWT setup..

 

...and plenum is plugged

 

No. I believe what happens is that crankcase pressure builds up leading to increased resistance to oil return from the turbo return lines, leading to seepage past the oil seals, either on the compressor or the turbine side. If you leaked on the compressor side, you likely have an intercooler full of oil and you'll be smoking for a good long while. Did you clean that out?

Are you sure the oil restrictor that comes with the kit was installed? With 2 breathers on the valve covers, you should not have an issue with crankcase pressure unless your rings are in really bad shape (with bad leakdown #s). Either that or your turbo seals are shot or your oil restrictor was not installed or your oil restrictor is not small enough for the oil pressure you are running.

 

Ok, exactly what I was thinking. I'm going to check oil pressure leading to the turbos. The reducer was installed but may need a smaller one. When my cats were in, I had no smoking issues, only with test pipes. I talked to Garret and they said the turbos are very sensitive to vacuum, meaning the turbos prefer the backpressure of the cats. I will likely try a smaller oil restricted once I measure presure, and may go to a heavier oil. If that fails, HFCs...

 

So i have a question.
I have a setup very similar to this:



Just without the tee fitting and no hose to the manifold.

My question is, for the last 2 weeks, I've pulled a good amount of water out of the catch can, no oil or anything, just water. Before I was turbo, i would get a small mix of both with the standard setup. With this now it's just water. Any ideas why or if I should even be concerned with it. The water smells of gas also.

 

Sounds like Headgasket problems to me

 

A compression test would show if I had a HG problem. Last compression test was less than 500 miles ago and was perfect just about.

Also, there is no oil in coolant and no coolant in oil. No bubbles in exp tank and no smoke out of exhaust. :/ I was worried that was an issue for a bit and so did my friend, we checked everything we could think of.

I wouldn't mind if it was though, good excuse to build motor

 

Perfectly normal by product of combustion - no worries.
