engine and drivetrain Valve Stem Seals

[Timo02]

What are the "correct" or "new & improved" valve stem seals to use on the '02 engine and where can I get them? I understand that there are the valve stem seals that work and the ones that don't. Please advise. Thanks to all in advance. Happy '02ing!

The style of valve seals is dependent upon the valve guide that is in the head. BMW changed the guide and seal mid way through the 02's run. If you install new valve guides in your head, you'll need the new style seals. If you re-use your old guides, you'll need to measure the top OD of the guide. The "old " style seals measure about 14mm ID and are part number, 11 34 1 256 556. The new style measure about 11mm and are part number 11 34 9 059 169. If you buy a head gasket set, it will come with the seal that your car originally had, you'll have to buy the new style seals separately. Hope this helps.

I've found that most sets come with the old style seals-

I've got tons of 'em, and most of the guides are now new style!

There's an Audi interchange- does anyone have the Audi part #?

Hi all,

I asked this question regarding the "new"style valve guide with a well known '02 specialist/tuner here in California and he suggested to go with the 320i valve guides and matching seals. This is what he uses. Thanks for the tips/advice! Have a good one.
