Hi the se has just been for service at a mates garage and have noticed oil coming from the metal pipe going to the inter cooler. Any ideas what the problem is?

Leaky seal on the boost pipe probably.

there will always be some a cleanout now and then won't hurt as long as you're not using more than "normal"

I hadnt noticed any loss of oil but you could see it had been dripping. Take it It's worth while be lacking the pipes off and cleaning them out then
