Symptoms of an oil soaked intercooler?

[rb68rr]

As far as I know my intercooler has never been cleaned. I can't run over 14 lbs of boost on 93 octane without getting knock. What are the symptoms of an oil soaked intercooler? And also what causes the oil to get in the intercooler in the first place? What is involved in cleaning it? Thanks, R.B.

Well 1 symptom could be knock from oil getting into the combustion chambers. also could get some tail pipe smoke.

The oil comes from the passenger side valve cover oil outlet to the turbo inlet bell. If you have replaced this with an open element filter already then its coming from the turbo seals.

Cleaning is as easy as pulling out the IC and using a carb spray. just spray it into the IC then shake it up and repeat a few times.Then let it dry out thoroughly.

If you take the up pipe off you can see if oil has been going through the intercooler and uppipe and into the throttle body.Common causes for oil in the intercooler are 1.Stock breather on front of passenger side valve cover. 2.Bad turbo seal.If you have the stock breather buy a breather and plug off the hole on the inlet bell. To clean the intercooler,remove it and either spay a can of carburator cleaner or dump some gas into it slosh around real good dump out repeat if real cruddy.Let intercooler drain out and evaporate.An air hose can speed up the drying .

After cleaning one of the stock intercoolers with gas, the gas was coming out clean. I decided to let it sit overnight and the gas was black. It's a good idea to let it sit a while with the cleaner in it.

Much better is a combo of simple green and water... safer for you and the IC.... Let it sit for 5 or 6 hours fill the IC to the top all the way with it... then dump it and hose the heck out of it untill u get ALLLLLLL of it out... then let it dry out... You can even bake the IC in the oven for a short time to dry it faster (im not kidding... mom/wife wont like it, but it does work!)

just make sure you dont use no flamable cleaners if you do that. i can see the headlines now, "man found accross state line after mysterious house explosion"

200mph AIR WORKS GREAT!

Crank up the Leaf Blower & attach to an inlet/outlet pipe to dry it out...works great!
