Title: Breather question... = high idle?
Post by: Diamond Black Geezer on 04 November 2014, 16:16:16
The 'breather bridge seal' has perished. I ordered a new one from Vx today, but that'll be a few days coming.

Basically - can this potentially leaking seal be the cause of the high idle, then hunting? If not, then I can refit the duff seal as it was before and get on looking for other leaks, change the ICV etc... Otherwise, Due to Monday and Tuesday being the only days I can get on with the car, that means nothing until next week, that's all.

Rest of thread here -

You mean the seal that is nicknamed the 'top hat'? Yes it can definitely cause an erratic idle. When I found mine it had split in half   :o replaced it with a spare one and it sorted the idle. Also check the two o rings that go from breather bridge to throttle body. . . I swapped mine for fatter ones that I got in an assorted o ring pack from hell frauds and that was sorted also.

Much appreciated!! Well I have ordered one from Vx today, as it's less than £2, so hoping this may be the elusive cause of my woes :-)

Next Q...

What is -

90500983 ?

this is listed as 'O'RING, CRANKCASE VENTILATION - where does this go? I've ordered a 'top hat' seal, and two of the small O-rings that go on the end of the breathers into the throttle body. But I've just noticed this on the parts diagram, so just wondering  :) Thanks all!
