Just because I'm tired and thick sometimes - where did you fit the halfrauds o-rings? Is that the two pipes that go into the throttle body?  :)

Correct :)

I played about with the fitment of various sizes and finally selected some ones that were about the same diameter as the OE ones but just slightly thicker :)

Exactly! And no offence taken btw ;)

Thing is if they failed shortly after..... i'd take the ten mins to put them back. no biggy. but the OE ones were not working for me. i replaced them and now i have no vac leak. simplez  :y

The question you need to ask is why weren't the correct o rings working.......as you have addressed the symptom......but what is the cause....  :y

Lol, sadly the engine designers will be considerably better paid, trained, more experienced and qualified than you or I in such design items so they generally get it right. I suspect the V6 engine has been produced in numbers of between 250-500K units and its an issue not been seen before....... ;D :D :y

Do be aware with the setup that the hole in the throttle where the breather bridge tubes go taper in to grip the O rings.

Can you get a pic of the plenum top with throttle assembly fitted and breather bridge removed?

Anyway, where have you been lucky enough to find a cave with power!

Yup. Sadly the Accountants will always have an input in the design of anything, even a Bugatti Veyron... (admittedly in that case not much of an input!  :y )
