Good point. My focus is on your big but. Do you know how easy to check the oil in inter cooler? Or what are the other ways I can make sure I am not having run-away condition. Please list the easy ways first because it is cold here and I can only spend small amount of time outside. Your help is much appreciated.
If you do a search you will find the quick way and also some who like to completely clean out the intercooler. It's normal to have oil residue in there....you just don't want a ton of oil build up.
The intercooler lower hose should be in the front passenger side of the vehicle. You have to take the clamp off one end of the hose and then stick something in there (some use screw drivers just don't rip the hose) this will create a void between the sealing surfaces and allow any collected oil to drain away.
If it has never been drained before do not be alarmed by a large amount of oil. The idea here is to drain any oil out, monitor your oil consumption, and then check the intercooler again for excessive oil collection. Excessive oil in the intercooler in a relatively short period of time would have me concerned about turbo seal issues.
If you have problems with the forum built-in search, try doing a site specific search with google.
