I bought a cheep ebay air intake the other day and when i was messing with the stock air box i noticed that inside the hose there was oil. I kept looking deeper and the oil seems to go all the way to the intake manifold. It is on the outside of the manifold and the flat box like part for the air intake right in front of the engine. I have no idea if this is normal. Please help!
Thank
oil in the 2.4 is no big deal. if youre really concerned about it get an oil catch can and put inline between your pvc and intake
Eat my shift
Ok i was just making sure that its not gonna have any long term effects or anything like that. Thanks
nope should be fine. just keep doing regular maintenance and the car will be fine. ld9s can take a good beating as long as you make sure they stay filled with oil.

Well i also noticed that my oil low light keeps coming on, but i have kept checking the oil and everything. It has plenty, but not over filled, and yet it still comes on. It usually takes about 2 min tops and then the light goes off. I am quite confused by this and it was giving me a little scare but i keep checking the oil and there is no change. Its been doing this for about a month. I cant tell a difference in anything except that dang light.
maybe your sensor is bad, maybe its just time for an oil change/filter
Eat my shift
Thats the thing, I changed the oil not even 1,000 miles ago. Ill have to check the sensor.
there is a breather tube that runs into the air intake... crankcase ventilation , PCV.. whatever you wish to call it..
anyways... because of where its located, its easily missed and might not even be attached at all... that could cause oil to get everywhere on your motor..
Now if your talking about inside the air tract... thats normal and what that little tube does (even cheapo ebay intakes have their own tube)... heres a simple explaination of the whole thing...
Quote:
....recycle the blow-by gas back into the engine intake. However, due to the constant circulation of the oil within the engine, along with the high speed movement of the crankshaft, an oil mist is also passed through the PCV system and into the intake. The oil is then either burned during combustion, or settles along the intake tract, causing a gradual build-up of residue inside the inlet path. For this reason many engine tuners choose to replace the PCV system with an oil catch can and breather filter which vents the blow-by gases directly to atmosphere and retains the oil in a small tank (or returns it to the sump)
So your suggesting that this breather tube could be off, causing my oil to leak onto my engine and intake? Would this make my oil light read different then?
well... somebody obviously had the intake off my car before i bought it and didnt know wtf they were doing... and they left that breather tube simply crimped and tucked out of the way (because its a bitch to get it to stay on while putting that airbox back on the TB).... needless to say, i have oil all over the front side of my motor, injectors, intake manifold etc... so it COULD certainly explain some oil...
But that oil would be burning off or sitting in the intake, it doesnt affect anything...
Now for your oil light coming on... well if you check your oil and you have plenty, i wouldnt worry too much about that... lol
Not something you should just ignore. I have a 2.0 turbo engine and has crankcase ventilation filters in the valve cover that was choked off and oil was showing up in my air filter box . All I had to do was take the valve cover off and disassemble them clean with gas and a toothbrush then all was good.
Ill have to check that tube. I had a friend want to help me put my intake on and i have a bad feeling that he just left that off. Ill get on that. lol

I have no idea what kind of 2.0 turbo you have or the design of its pcv system... But there is really no way for oil to get into the airbox on our car... the pcv tube dumps into the intake half way between the filter and the throttle body... oil is not going the opposite direction of the air being sucked in... and gravity keeps it out when the car is off... unless something went boom...
I am not completely caused this to happen but the head gasket did go out shortly after and it sounded like a diesel down a couple cylinders, there are 3 metal grilles in the left side of the valve cover then a hose travels to the air cleaner, that is where my oil was coming from, actually spraying on the filter believe it or not.
that engine had 443'000 km on it and it had a few oil leaks
looks like that valve cover isnt sealing.. lol.. thats a messy motor...
but yeah... its a completely different motor then what the OP has..
