Hi all, looking to tap into the OOF collective knowledge.
I am planning to clean the crankcase breather setup as per the excellent detailed guide elsewhere on this site, to try and tackle the persistent oil leak that my 2002 2.6 V6 has.
I understand I should need (depending on the state of the originals when they come out):
Breather bridge to plenum "tophat" seal 1 required - 90467543
Breather bridge to throttle O ring 2 off required (4 of on extended plenum's) - 90500983 - I already have 3 of these original GM, just need 1 more.
Inlet to Plenum O-rings - 9118135 - 6 requiredDoes anyone know where I can get replacements for these? Have tried Autovaux, eBay, multiple internet searches, my local friendly motor factor etc. I think someone mentioned a couple of years ago on this forum you could get parts such as the tophat seal from the USA? Would that be from the likes of RockAuto - as far as I can tell they only have the set of 6 o-rings (9118135) up for £35.
At the moment there is also an original new/old stock tophat seal in Germany for £59 plus postage?

Any pointers or hints gratefully received.
