C30 Engine : - 2.0d oil throttle body

hansC30 · Feb 25th, 2018, 18:05

Hi all

I still have troubles with my car. I just took the throttle body of and noticed that oil is leaking at at the connection between the intake manifold and the throttle body. The bottom side has drops of oil on it and the vacuum lined beneath also have oil on it.. Shouldn't only air go through the throttle body?

I also think my turbo isn't de levering enough pressure. It seems slow in building up the pressure. I can only test it stand still though since vida is on a desktop:-)

No errors on vida btw.. High fuel consumption as well, 7-7.5l/100km and that is 6.8 when I really try hard, not going above 2000rpm.

Any help would be so much appreciated!

That's oil from the turbo which is normal in small amounts but it can build up in the throttle body and intake manifold.
It needs cleaning out .

I tried disassemble the intake manifold from the engine today but saw a sensor going to the Cambelt which I did not dare to take off. Can I just do this or should I be careful with this and leave it to a technician? I would like to clean out the entire intake manifold somehow..

Taking off manifold is a bit tricky, so would depend on your ability.

I disconnected everything, all sensors screws, egr pipe. and the manifold was coming loose, except for at the side of the Cambelt where that sensor is attached. Also, there is a pipe running from where you fill the oil to the back top side of the engine, it is secured with those special iron locking rings without screws, not sure if these can be taken of and put back easily or have to be replaced? Could I just secure it with these metal rings you can tighten with a screw like on the throttle body? What is this hose for exactly? Also at the side of the Cambelt you need to disconnect the front screw of the cap that's over the Cambelt. This screw was very wet with oil, what's behind that on the intake manifold?
