question about oil in IC piping

Jake26 · Oct 29, 2009, 02:25 PM

hey guys i took my upper IC piping off today to clean it and noticed some oil inside.. it wasnt bad, few drops but the pipe inside was greasy with oil as well.. closer to the turbo.. is that normal?

Not a pro. But that doesn't sound good, because the oil flows around the sealed inner bearing of the turbo. And if its leaking oil into the turbo housing that could lean toward some serious problems if its being fed into the motors (throttle body) intake. Once again not a pro but it might be likely.

If your valve cover breather still connected to intake, there are going to be oil fumes that are sent to the turbo inlet causing what you described. OEMs do that to ensure that all the fumes are sent throught the catalytic converter for emmisions purpose.

If you were leaking oil from the turbo, you would see a lot of blue smoke coming from the muffler at high load on the car.

It is hard to tell with a description if the oil you found there is from what I am describing. My suggestion is that you bring your car to an experienced mechanic on DSMs to check it for you. You should do it pretty soon!

should i take it to the dealer? the car is tuned and has injen upper ic piping.

i have actually let my friend drive the car today i drove behind him, the only smoke i saw coming out from my muffler is when he really got on it, so it was fuel being burned. he has a evo x he checked it out and told me it was normal.. but i will take it to the dealer soon.

Here is what i found on DSM forums..

i quote

"Well, i decided to discect my car today and i found oil in the lower intercooler pipe, upper intercooler pipe, and the intercooler itself. i took the j-pipe off my b16g and i found no oil inside the turbo itself, just in the pipes. however i am quite confused because my turbo spools, and boosts normally. ive had it at 22 psi without a problem, no smoke or anything. is it possible for a turbo to leak oil, yet still perform like its brand new? if not, what else could it be? perhaps recirculated hoses from my throttle body? (owner before me recirc'ed a few outlets on my tb, i still dont know why or what they are..)"

then answer

"it is normal to have some oil residual in the pipes. If you want to lessen it greatly get a oil catch can from road race engineering or take the hose from the valve cover that goes to your turbo inlet tube and cut it two 4 inches from the inlet pipe. Run the part that comes from the valve cover into a breather filter and hang it down and then cap off the line that goes to the inlet pipe. Remember that the environmentally right way of doing this is the catch can and disposing of the oil at every oil change with the oil your disposing from your oil change.

Yes! Take it to the dealer and make sure you get their findings in writing. For warranty purposes.

HMMMM. That is very interesting. I wounder if this is something that should be done or not? Why wouldn't Mitsu do this? I dont want any oil to accumulate in the UICP FMIC LICP or my intake. Would this fuel filter take away any performance from the recirculating air? I am very puzzled about this.
