STILL oil in intakes

[TW]

So if you guys read my last thread, i was having intermittent maf failure. This was being caused by oil in my intake piping.. After cleaning all the piping out thoroughly, the issue was resolved. But yesterday, i was driving the car, and low and behold i felt the car buck / hesitate. So i pulled off the intakes, and there was oil in them.

I need to figure out the cause.. It's getting pretty tedious. Checked inside the breather hoses, theyre pretty oily. Compression is near perfect though so i cant see excessive blowby being the issue. Removed the pcv valve, the little ball/dohicky inside moves back and forth like it should.

So whats with all this oil everywhere??

I was thinking turbo seals... or clogged/obstructed return lines, but i'm not getting any of the other symptoms for this. No blue/white smoke out the exhaust. What would i expect to see if turbo seals were gone on the cold side? or restricted return line?

The other possibility is too much positive crankcase ventilation.. which doesn't make much sense to me either.. why is there so much oil in my pcv/breathers??

Any help / ideas is welcome guys, i just want to get this settled.

I don't suppose you've over oiled your filters?

[TW]

nope, theyre unoiled apexi power intakes

How much oil are we talking here. There will always be some. That's why people run catch cans.
I don't think the oil is what is causing your problem. Bucking and hesitating sounds more like an ignition problem if it's very abrupt or maybe fuel (less likely).
If the car runs great for awhile and once it gets warmed up and you start dropping a cylinder I'd be looking at your ignitor. I just went through that.
Which motor are we talking about here?

I cleaned the intake pipes, intercooler + piping, suction + breather hoses last week. If i put my finger in the breathers, it comes out pretty oily. lol that's what she said.

Its just worrying me that the oil gets into the intakes.. its pretty noticabe. took off my mafs and stuck my finger in the rubber hose before the maf and that one was pretty oily as well. not as much as the breathers but still. Seems like alot of oil since i cleaned everything THOROUGHLY 1 week ago.

Ignitor eh?... it does seem to do it once everything is warm... but at they same time, ive always thought it was due to the oil getting to the mafs...

When it actually happens, i usually lose all power instantly, and it will die.. then if i start it a few times, i can get it working normally again

[bobbo]

How long until it starts again? How long until it acts up again?

[TW]

take yesterday for example. I'm cruising at 3000 rpm in 3rd. Car loses all power. I put it in neutral and try to rev it up to keep it alive (this usually works) but it died. pulled over and started it up again, died. Started it one more time while on the throttle, and it was fine.
Then, i picked up my girlfriend, and was driving back to her place.. this was about 15 mins after the original incident. The car lost power for a second, as if it was about to have the issue again, but ended up being fine. so strange

Is there much info on your car in your other thread? If so post the link so you don't have to repeat yourself. If not what mods are done?
I'm still leaning to an electrical problem. Likely ignition.
Also when it starts acting up pull the plugs. Check for any cylinders that aren't firing.
I wouldn't think that after only 10k on those turbos you'd have seals going on you.

those were the two previous threads.
When i took off my intake pipes to check the first time, there was almost a tiny puddle of oil in the one fror the front turbo lol

For your oil problem Oil seals in turbos may be causing the oil or more likely put a catch can in between you crank vent and you intake inlet pipe if you haven't already.

I had alot of oil in my intake piping and my maf's got really dirty and it never cause my car to stall as a result I would recommend looking for electrical problems.

If you can get a consult and drive around and check the maf voltage.

I am having the same issue as of 2 weeks ago.
Turbo is good, PCV is good but lots of oil getting into the MAF (you can actually see the oil on the backside of the sensor) Problem is solved by blasting the MAF with brake-clean and cleaning out the intake it's good for a few days then. No idea why it's happening but it's annoying.

I'm just going to get a catch can and see if that helps.

I had a 99 Golf and it would die whenever everything was warmed up. Was the CAS. Sadly, it does not explain your oil issue. Good luck!

[DarkCaporaL]

Yeah I would check the CAS for your random stalls. Signs of a failing CAS.

[TW]

it's not just stalls though, its misfires / hesitation as well. i posted up a vid in one of my other threads..

Its like i'm driving, i lose power, then it misfires and smokes like crazy if i try to give it gas.

still sound like CAS?
Is there a way to test it other than swapping in a known working unit??

Its weird. its not just when the car warms up. Once it starts happening, i could leave the car overnight and it will still do it in the morning. But if i leave it for a week, it'll drive fine for a while before going wonky. Which leads me to believe that its oily mafs
