Air-to-water intercoolers rely on the engine coolant and can often develop clogs due to mineral deposits. Clogged intercoolers will cause an increase in the temperature of the air flowing into the engine, thereby reducing its efficiency.Should there be oil in the 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.Can I drive with a damaged intercooler?
If an intercooler has a leak it should be replaced as soon as possible. Driving the vehicle with a boost leak will result in turbo wear, or failure, as the turbo has to work increasingly harder to achieve the desired boost pressures. This can result in the turbo's maximum safe RPM being exceeded.How to do a Intercooler clean out, Seriously go and do this to your Intercooler!
