What would cause oil in intercooler?
What does cause this is a worn turbo (bearings and oil seals) or the PCV system. There is a shaft with a couple bearings in the turbo which are lubricated by engine oil. When the bearings wear or the oil seals wear, oil can make its way into the pressurized side of the turbo and be pushed into the intercooler.
What causes intercooler to fail?
Common Causes of Failure Internally, damaged or blocked hoses may lead to abnormally high pressure that strains or possibly rupture the intercooler. Finally, installing a turbocharger incorrectly can cause the intercooler to clog and sustain damage.
Should there be oil in intercooler?
The intercooler is not meant to have any oil, neither by operational requirements or design. Your turbocharger runs at speed up to 280,000 rpm, and from your engine lubrication system, it is lubricated by oil.
How do you check if an intercooler is leaking?
“What mechanics, and the drivers, can often identify a defective or leaking intercooler on is: a noticeable drop in the engine power, increased fuel consumption or unnatural smoke from the exhaust system.

What happens when an intercooler goes bad in a car?
Intercoolers and turbo plumbing are fairly simple things by nature, and there aren’t too many ways they can fail. If an intercooler or the plumbing between your turbo and engine leaks, they’ll vent boost pressure to the outside and cause a net loss of oxygen going into the engine.
What does an intercooler do in a turbo?
An intercooler is a heat exchanger that goes in between the two turbos in a series turbocharge system, while an aftercooler goes between the final turbo and the engine. But whatever you want to call that radiator thing in your turbo plumbing, it plays an important role in helping your engine…
Why is my intercooler hissing near the brake booster?
The hissing you noted near the brake booster could be one of those little vacuum lines that tend to rot out. You can buy that hose in bulk and replace it all. These hoses are very important as they control turbo operation, EGR and anti shutter operation and some other little control switches.
