Hi guys, I am finally getting round to getting on with making my r53 bought 3 months ago into a useable car with track abilities also.

Yesterday I went under the bonnet tom make a start in the engine bay and found the following:-

Underside of the air filter was so black & mucky it is a wonder it was allowing any air through.

Intake ducting & manifold downstream of the breather inlet was completely coated in black oil film.

Are these normal?

I will be removing the front of the car to get the S/C etc out to clean/check/oil/modify the S/C & pulley etc maybe next week so will get it off properly then for a good clean, but it there anything else I should be looking into at that time?
