Ok how much of a pita is it to remove the inlet manifold so i can clean the ports etc., I suspect they may be blocked. The reason being the engine seems to make a knocking noise on one cylinder, due to combustion i think, and, when the air hose is off the main intake pipe there seems to be a slight "blow back". The turbo seems to be all ok but the slight blow back may be because of a blocked inlet track in the head/manifold ????
The knock does seem to be getting a bit less as i added some fuel system cleaner and left to engine running at 15 to 2k revs for about an hour each time, and drove the car yesterday.
Any thoughts??
When starting there does not seem to be a lack of compression on one cylinder, and the injectors all seem to be as warm/hot as each other when engine running. No smoke seen and oil level is as before, virtually no oil used between yearly oil change, but the slight leaks do seem to be getting a little worse.
