Mark 1 - 2.2 Hdi Oil Leak

[Bobster]

Hi,

 

I have just changed the oil & filter and while the undertray was off, noticed

signs of an oil leak. Oil is present on the bottom of what I think is the

intercooler and on the large diameter pipes which I guess carry the air from the

turbocharger. I cannot see where it is coming from, indeed I can't see any oil

pipes in the vicinity, so would appreciate any suggestions as to where to look

as Haynes does not cover the 2.2 engine.

 

Also, can someone tell me how to remove the airfilter box as I might get a

better view from above?

 

Thanks in anticipation.

It could be from the intercooler and pipework. There will always be oil inside from the turbo so may be worth pulling off a hose and letting any excess oil drain out and give everything a clean. If this is the source then as long as it is not excessive is unlikely to be anything to worry about.

 

There is a French ETAI manual that covers the 2.2 hdi, book CIP 654.1 and usually available from Amazon's French site. It does not cover removing the air filter box though and neither does the Citroen service manual for the 2.2 hdi so it may just be a case of removing the filter box cover, the air mass meter pipe and electrical connector, any other bits and pulling the box out.

Thanks Paul, have been told elsewhere that it is most likely a small air leak in the turbo pipe or intercoller which is carrying some oil spray with it. As the turbo is working fine & it does not seem to be affecting performance, I will keep an eye on it for a bit.

 

Best wishes, Bob H.
