Well, I came home from class today to take off my intercooler (which I have done several times before.) to assess what obstacles I will be facing when my CP-E downpipe arrives in a few weeks. Well, after i remove it it looked ok, and I was checking out the downpipe and the turbo when I notice that there is some kind of liquid setting in the feed hose from the intercooler to the throttle body. Well come to find it mother F*cking motor oil! I check out the feed hose from the turbo to the intercooler and there is a shit ton sitting around the lip of the turbo where the feed hose connects. I check out all parts of my intake and ever single gad damned piece is coated with oil. It's not a drop here or a drop there, take out your oil dipstick and feel the oil. That's how much is on the walls of my intake. The only modifications I have that due with the performance of the engine is NOTHING. I am still waiting on the intake and the exhaust but besides that, NOTHING. I am a little pissed as some may see, but has anyone else seen this? :x

sounds like there may be a need for a catch can on the breather line

I don't know but in any case im burning oil this way. My oil level is still the same as it has been for the last 1000 miles (last oil change). Hopefully its not the seal on the turbo or anything that will take them weeks to solve.

I suggest checking it since it only takes about 10 mins. 10mm socket and 12 mm socket. 7 bolts and 2 hose clamps. I'd check it. anyway I'm going back to the dealer at about 5:30, they close at 6, to get an update, they started on it a few minutes after it dropped it off. I'll return with news if any.

Every IC I've taken off a turbo car has had a little oil in it. I was always told it was normal as long as there is not like a POOL of oil in there. Never dealt with such a new turbo though... all my experiences were with DSM's and early Scooby's.

Yeah, it's pretty common to have a little blow by. Byproduct of a thing in your engine spinning @ 100,000 RPM. Unless it was insane (and it doesn't sound like it was) there's nothing to worry about.

well i took it to the dealer since the past 2 times that i have removed it there was NO oil except a very very very small thin film, but you had to use a wrag or something to see it when you wiped it off of the walls. when i used my fingers before this, it was just as oil as your finger when you sweat. But this time is was quite a bit.

Yes. Curious as well.

I could understand a bit but it was as much as you wiping off your dipstick of oil. And it was pooled up on the ledge of the turbo feed and the the hose feed to the intercooler.

I'm a turbo noob but I've read about this happening. Is the amount of blowback dependent on the size of the turbo? In the case of the MS3 (small turbo) would the amount that TV is describing be considered "normal"?

I'm interested to hear it myself. Seems like I need to be inspecting my intercooler.

As long as my oil level isn't falling (and it isn't), I'm not messing with it. I'm due for my next change in about 500 miles and the level hasn't dropped where I can notice. Anyway I hope the dealer doesn't give you crap about your mount or synthetic oil. I wouldn't say anything to them, let them find out.

well they said that it was normal. They called mazdausa and they said it was normal. they checked the pcv system and the intake system and there was no problem. But when I looked under my hood. they didn't even take the damn intercooler off! They probably only took the bov off and stuck their finger inside. My point is is that the intercooler will reduce the amount of oil build up durr.. I was mostly concerned about the pool of oil where the feed hose is connected to the turbo, there was just oil sitting there. o well if something screws up, at least its been noted that it was prior to any modifications. If it gets worse i think ill call up my original sales rep to look into it (good guy).

It is definately normal. There should be nothing wrong with your car. I have had 6 turbo cars, and they have all done it. My SRT-4 was really bad. Within the first 500 miles there was like 2 tablespoons of oil in the intercooler hose. I had to put a catch can on it. I was affraid this car was going to be the same way, and it sounds like it is. I was going to put a catch can on it right after I bought it, but never got around to it. After 4 months of driving, I can imagine what mine looks like! It does make a mess. A problem occurs when the oil gets all inside the intercooler and coats the inside (and it does). It pretty much takes the effectiveness right out of the intercooler. It pools up in your intake and makes a mess of it too. It will also gunk up your PCV valve. I don't know why car manufacturers don't put catch cans on turbo cars at the factory. Probably has something to do with emmissions. If you look at most any " tuner's" turbo car in any magazine, you'll see a catch can in the engine bay. I guess I'll be getting a catch can. I'm surprised it took this long for someone to bring up the catch can issue. Maybe someone has mentioned it in the modifications section of the forum, but I never look there. I'll wait till' the weather breaks to tackle it, I'm looking forward to the mess! Thanks for the heads up, now at least I know the car definately needs a catch can. :?

DLUX, you took the words right out of my mouth. This is one of the reasons why there are people out there like us to "compete" the circle of forced induction tuning. Oil catches will save you the hassle of cleaning the porous metal portions of your air delivery evey 5K or so. A friend of mine has a crazy ass Teg with 15lbs of boost through a t3/t04 hybrid monster and that thing blows oil all over the place inside the system. Nature of the beast my friends... and I would rather see some oil rather than NONE. Another reason for a bigger oil pan vs. NA.

On my '84 Mustang, I had to take the throttle body off and clean it every few months.
Oil by-products from the turbo would build up and prevent the throttle plate from closing properly.
