took my airbox off today to clean the air filters and first off the left side was soaked with motor oil and right side winshield washer fluid. figures why there is so much oil on my garage floor. I checked the oil level and it was short a quart and i just got the engine oil changed a month ago and drove it for about 800 miles. Secondly on the left side/driver side on the air box there was the most oil and goo right by where that tube from the valve covers goes into it. last and not least after taking the air box out i started the car for a sec and out of the tube that comes out from the valve covers and into the left side of the air box there was lots of smoke that stunk like crazy. is this normal for all that smoke to come out of that tube?

The oil from the valve covers sloshes forward under hard braking, and gets ingested into the airbox from the breather hoses. Even if you don't brake hard, there is always an oily residue that accumulates from the heavy vapors.

Road racers take the breathers, and either relocate them to the top of the valve covers so the oil won't slosh out, or just route them to a catch can, and plug the airbox breather inlet.

As far as the smoke, sounds like just hot oil vapors.

Besides braking, the SC when in boost will tend to increase blow-by. I installed a catch can in my return line to catch most of the oil before it made it into the air filter. Losing a quart in 800 miles seems like more than you should be losing to me though unless a lot of those miles were under boost.

I assume that you have your water/**** injection up near the air filter? If you position it back closer to the throttle body, that should reduce the chance of the filter getting wet.

Get a catch can. You're getting the "super charger blow by".

That's exactly what I had and you have to either change your piston rings or get a catch can.

Here's what I did on mine. I used a small Jaz puke can and put it in-line with the vent line from the valve covers to the intake box. I mounted it loosely where you see it in the picture by the brake reservoir. With the hoses coming in and out of the can wire tied down, the can is pretty secure. The hose runs a little uphill from the valve cover connections to the puke can which helps to encourage the oil to stay in the engine as much as possible. A hose is permanently plugged into the bottom of the can and run down by the PCM grounding stud. I can put the hose in a can and open the petcock to dump the oil.

I blocked off the breather vent in the puke can as I wanted all the blow-by gases to recirculate back into the intake rather than venting into the engine compartment, while the puke can catches most of the oil. This prevents the engine compartment from getting that nasty smell that you got when you disconnected the vent line and also maintains the emissions setup should anyone ask. I put a fine SS mesh cloth in the can to help separate the oil from the air as it passes through, but I don't think it is necessary.

I need to dress up the hoses a bit, but this setup seems to work fine and I have no oil in the intake.

Definitely get a puke can setup. You don't want those oil vapors sucking back into you engine anyway, it can cause detonation.

Hey Dimitrios,
I don't know if you saw my setup, it is just a small compressor airline filter $10.00 - $20.00 depending on size with a in and a out then back to my intake, I haven't had any problems at all with oil accumilating in my airbox, here is my photo again, it can be mounted almost anywhere because of the size, it has a drain at the bottom plus the housing unscrews for emptying or filter cleaning.

I would be very concerned about the amount of oil you are talking about. Normaly oil will only push out under hard braking, in your case it sounds like it could be blow by.

A leak down/compression test may be in order.

Here's an excerpt from The SC installation manual:

(61) Now we need to setup the crankcase breather system. You have two options available depending on your use of the car and the engine condition. We found that under hard acceleration with the engine hot, dense oil vapors (blow-by) can contaminate the intake air, which in excess could cause detonation (with or without a supercharger). Some cars have more blow-by than others.
Option #1: Leave the original valve cover breathers in place, which run together to the air filter housing.
Option #2: Use a push in valve cover breather(s) vented to a catch can. This requires putting a hole, slightly less than 1.25”, in the valve cover. If you do extended track events (road racing) or your engine has an excessive amount of blow-by (worn rings), you should install this breather in the forward upper corner of the drivers side valve cover (determine the proper location by looking at the valve cover from the inside). It’s not necessary for regular street use. A good oil separator / breather to use is the Moroso part # 68781, which is available at speed shops for about $7.

Additionally, if doing track events, we suggest the following:
- Use race gas.
- Put a tie wrap on the dipstick handle to hold it down.
- Consider installing a second valve cover breather.


We used to put those Moroso breathers in the installation kits, but found nobody was using them. I've had one on my car for several years now and have no oil, at all, in the tube running to the air filter housing. We're working on a screw in breather also, for those that don't want to put a hole in their valve cover.

Regards,
Sean
