Thats what you need if your getting oil in the inter cooler....

waggy3

is that because of back pressure

The breathers from the engine do chuck some oil out. This then is fed back in to the turbo intake pipe.....which then obviously goes in to your inter cooler.

what ituck out of the inter cooler could fill a cup
and have found out the last person to have the car was a trader who put oil thickener in the engine oil

Sounds like you need an oil change as well then!!

To be honest I don't know how much oil is normal. But catch cans are a lot bigger than a cup.

scooby-k

petrol is pretty good for cleaning it out.

There are two issues which can lead to oil in your intercooler....

OE cars have the head & crankcase breathers vented to the air intake, the thinking is that the vapours are just burnt off in the combustion process. If you bypass these to a catchcan then you don't have any oil vapours returned to the intake.

If you still have oil in the intercooler after doing the bypass mod then your turbo seals are probably on the way out and letting oil back into the compressor housing. Turbo service would be recommended if it's bad enough.

You need one of these....

I have been looking at these recently and was surprised that Crawford Performance - the people who prepare Ken Blocks engines / cars - have a stage 2 sti package of ecutek + downpipe only + air oil seperator . Never seen anybody recommend such a device as a basic tuning mod... must be good ?

What turbo is it?

You can get a TD04 for around £50 and a bit more for a TD05.
I paid £200 for a VF28 which had been refurbed.
