hi,
have just had a tinker with the car, started to do the EGR kit, cannot get bottom hex stud out as it is tight, so penetrating oil and a hex socket required, took map sensor out, the one on the inlet manifold, oily!, give it a clean, now the question, haven't quite got to take ing egr off inlet end yet, but i suspect inlet manifold is a little oily, will this clear up as i can only clean what you can manipulate with a rag etc, don't know what intercooler is like yet,
