Title: V6 Breather seals and O rings
Post by: addy on 22 March 2018, 13:37:11

Hopefully someone can help?  I am looking to do a breather clean on my 2.6. I have rang the local dealer who say Breather bridge to plenum seal - 90467543 is no longer sold and there is no alternative.  Could anyone tell me if they have found an alternative or where I can get one?  They stock Breather bridge to throttle O ring - 90500983 but have to pay £9 up front for 5 of them.

I would prefer to get the plenum seal if I can, as the way my luck goes the one on the car will be damaged when taking the piece off.

Thanks in advance for any help.

See similar thread below from James V6CDX. The 'top hat' seal may be available from Autovaux, otherwise if yours is not too bad re-use yours.

Thanks for replying. Having one of those days and missed the other post.  Ordered it through Autovaux.

I would try and clear the passages with the breather attached to the plenum first. If you can squirt carb cleaner through from the rear, then there's no real need to disturb the top hat seal.

Will try that thanks. Is there seals from the Throttle Body to the Plenum?

I think all other the other plenum seals are simple O-rings. I bought a box of assorted O-rings from Machine Mart years ago, and it still meets all my usual O-ring requirements.

No, it's between the black plastic breather housing that sits on to of the plenum to the plenum itself.

Yes - o-rings
I have never needed to replace one though.
