Found my problem (crank case venting)

so, the other day i started my car, drove it around the block,a nd then smelt oil
Thought it was the turbo drain, welll, did it again today, and its pushing oil out of the seals.

So, my question

1) just install a breather on the passenger side valve cover

2) Take the passenger side "breather tube" and disconnect it from the TB, then run it with an oil seperator and connect it to the inlet side of my turbo?

I'd suggest you research this some before you decide. There has been a lot of discussion regarding this issue with a F.I. motor. The bottom line seems to be choosing a breather system that is adequately sized, as some people were experiencing similar problems after they installed what you were describing above. This was due to the fact that the system was working, but it just wasn't adequate when in higher boost levels. If in doubt, run a -10 line from each valve cover to a vented catch can. Try searching in this section a little and you will find several discussions on this topic.

Let me know what you find out. This could be my problem too.... Got oil pretty much everywhere. Its not leaking from the intake or valve covers....

boostedz28, i searched and found that most people do the two things i mentioned.

The -10AN lines though, on the passenger side would that come out of the "breather hose" area, then i'd have to tap the driver side?

If nothing else, I will run the Mr. Gasket exhaust setup

The problem that some have experienced with either installing a small breather into the valve cover, or installing an oil seperator into the 3/8" existing breather tube, is that it is not adequately sized for the amount of pressure created in the crankcase when the motor sees higher boost levels. In cases like this, one answer is to attach (best acomplished by welding, but can be installed other ways as well) AN style fittings to each valve cover and then running a -10 line from each v.c. to a vented catch can. This eliminated any oil from being pushed out of the motor and/or blowing out seals.

I have had alot of issues with oil as well, I tried the breathers and it helps a little bit but the breathers get saturated and still mist oil out on the valve covers. I just installed 2 new valve covers and ran 5/8" line from the passenger side valve cover and the pcv valve out my intake into a air/ oil seperator and too the inlet tube on the blower and i have seen a huge difference, and i have no breathers at all now.

well right now, the most boost it will see is 10psi on this build, and modifying the VC's is a PITA since i have to take the passenger side header off to get the pass. VC off

I'm supprised nobody has caught this yet, but your problem is that you have your passenger breather hose still going to the throttle body. That needs to be either a breather or to the inlet side of your turbo. Basically, your pressurizing the daylights out of your crankcase with it still hooked up there. Cap it off at the TB. I even had to use a small wire to wrap around the flared end once capped off cause i kept blowing the rubber cap off causing a nice big vac leak. I'm running from the valve cover to a seperator to the inlet side of my charger and also a breather for an oil cap. I haven't seen any oil in the seperator either. Give it a try.

roguedriver, thank you.

I just needa get an oil seperator, where are you guys finding them at?

Buddy just bought a nice looking one on ebay for cheap, I'm going to go look myself.

Try these guys. It's what I'm using and it works flawlessy and pics up all the crap. Or you can go to home depot and pic up a cheap unit that may fail under heat.

I'm using one from Lowe's. It's just a water seperator from a compressor system. Nice part about those is you can see if your sucking any oil. Mine has been clean and free of oil and no problems with it at all.

My Vortech system was setup to run a tube from the valve cover to blower inlet. This would in-effect evacuate the case under boost (high pressure in the case and low pressure at compressor inlet)

I can't speak for efficiency of this setup but it 'works' for Vortech (at least I assume this was the stock Vortech setup)

I'm going to run just a cheap compressor filter from the valve cover to the suck side of the turbo and see how mine does. I may have already trashed a seal or two. Looks like either the rear of the pan or the rear main for me.

well, the way i did it would have worked, but the hose is too close to my pipes and keeps melting. Looks like I am going to have to ditch the PCV system all together and just run breathers or something on the valve covers.

If you are running a lot of boost (15+#'s) a catch can system similar to SRZ's is really the best way to go.

I am running about 15#'s through my car and all I have is a decent set of breathers (one large one on each valve cover, and one smaller one on each valve cover), and it does the job just fine for me. Under extended periods of heavy boosting I may have to wipe a little oil from underneath my hood were the breather misted it, and then check my oil level, but for the most part this works very well for me.

SRZ, what unit do you have, and how much did it cost?

well, i am going to run a breather tank from summit.

It'll work same as a breather, except it catches oil too instead of misting it all over.
