HI

What is the best method of cleaning the oil residue out of the top mount intercooler?

Any particular method or cleaner to use?

Many thanks
Steve

 

If you've had a turbo failure that's caused lots of oil ingress into the IC, then blow the surplus oil through with a high pressure airline. Do this in a responsible, environmentally-friendly way.

Then thoroughly clean the excess residue out using a "petrol bath", like you see in professional car repair garages/specialists, etc.

 

I just washed mine out with petrol.
