I've checked my Intercooler today as i'm suffering the 4th/5th gear syndrome. There is a light mist of oil right at the bottom of the Intercooler but not anywhere up the fins, is this normal?
I haven't found any loose hoses except one of the 3 small hoses that sit under the scuttle tray to the right middle of the car as you look in from the front, had become detached so i reconnected it, and also sprayed the MAF with contact cleaner as suggested in another post, seems ok but the true test will be the commute tomorrow morning?
