Today in an attempt to stop my intercooler getting black oily crud into it, I pulled the top vacuum pipe off the egr valve. Put a bolt in there and placed a tie back around it and put it to the side.
Firstly my cars a 53 plate but the engine light has not yet come on. I drove it about 10 miles in total? Does it come on after a certain time or immediately?
Secondly, how do I know the egr was in the closed position when I popped the vacuum hose off?
The car feels and drives the same. Been trying to resolve an issue with a lot of smoke on acceleration. Found the bottom intercooler pipe leaking at the joint where it goes into the intercooler. When I say leaking its covered with oily substance. Think I fixed it with a new gasket and tie backs etc. But surely that oily stuff shouldn't be there in the first place. Or does it appear if there is a vacuum leak?
Sorry for the numerous questions. Just a bit curious about what's going on.
