Oil In Ther Intercooler . . Help

[sIIgtst]

HI all i just pulled my intercooler off to give it a polish..

When i took it off and looked in one end there was some oil there so i sat it end to end with a container

underneath and i got about 20 - 25ml of oil after about 1 hour of it sitting there..

Cooler has been on the car for abit over two years..

would this just be a normal amount of blow by or is something wrong??

Cheers

i would say thats not good at all, get a catch can and if it keeps happening, i would be leaning towards getting a new turbo,

If it's been on for over 2 years, you get some oil mist from the cam covers/rockers that gets vented back to the intake side. It hits the intercooler piping, cools and condenses.

If you have plenty of mods and you've upped the boost and religiously give it some, its normal and thats why you run an oil catch can.

If you drive like Miss Daisy and your car is std then it could be rebuild time.

Was it all oil, or was it a bit white and had some water in it?

Hey it was all oil.. ive looked at the turbo and their is no oil on the inlet side or any shaft play.. it all seems good..

i do have it running at 6- 12psi and it does get driven hard from time to time.. ive had a catch can in it for around 6 months and thier is a few drops of oil in it

so hopefully it was just my cooler acting as an expensive catch can.. only time will tell i guees as its clean now and ill check again in a few months

hopefully the catch can solved it..

Oil is normal for motors re-circ'ing thier blow by (OEM style)

20ml's a tad excessive though. Clean it up, and comp / leak down test.

will get a comp test done asap..

But hopefully its nothing major just a build up of blowby over the last 2 and a bit years.

could be your turbo seal starting to go ive had that problem and it went on the exhaust side so after a fair bit of driving it would seem like im doing burnouts because of the burning oil :-p. also where is your pcv plumbed into if its even plumbed in. i would go along the lines of running an atmospheric catch can for a while and see if ya got any oil in the intercooler after. if results show you aint got any oil in your intercooler then i would go comp check to see the state of the piston rings :-) if you still got oil in your intercooler then yeh prolly a turbo ;-p
