aftermarket valve stem seals

[chris steedman]

here in the uk ducati charge over 6uk pounds per stem seal. car seals are 90 pence.

has anyone found a suitable replacement ? there has got to be one from a car that will fit ?

Got a couple from Guy Martin @ MBP. But one won't stay on the guide!

from my spreadsheet:
Valve Seal from MBP is EngineTeckEOK

Chris,
Contact U.S. Seal @ 1-800-777-6974 and talk to John Murphy. Web address is Valveseal.com . You'll be glad you did.

Chris,
I use BMW car valve guide seals, they're exactly the same and cost about £1.50p each retail.
I also shortened some Renault valve guides in Bronze?? they were a lot cheaper than Ducati ones.

Sweet , we all know what 4v stem seals fit what and where to source them.

Question 2 . Is there any better stem seals for the older 2v bikes ?

Picked up Goetze valve stem seals, exact Ducati match from WorldPac parts supplier @ $1.07 each.
Application from: 1996 Audi A6 V6 2.8L-12V

I bought a set on Ebay of the above. I need to dig into what they were for exactly but I paid under $10 usd for 16 if I remember correctly. They were for a VW

Hi Brad,
I'm Mr R from the 851/888 forums.
I bought the BMW seals from a local car/bike cylinder head tuner, he had a huge plastic bag of them and said "They're £1.50 each to you Steve"...
They were the exact same part as the Desmoquatro items.
I'll try and get the part number for you and the lads.
I'll do my best but you'll know how people in the trade guard their sources...

FWIW the desmoquattro seals I just ordered from Ducati superceded to a 696 monster part number?

I went down to a Mercedes dealer and asked around in the parts dept. They had some 7mm stem seals in stock and work great.

[chris steedman]

What about 2v ?

Sorry for the slow reply Chris. They were for my 748. I dug around in all my info and pics this past weekend and I am pretty upset with myself. I found no record of what I bought. Man, what was I thinking

Hello,
This is my first post here. I have got a ST4s with a 996 engine.

Well, I had this same problem with more than one (VW seals), the last time I rebuilt the heads. Is there needed any type of glue before putting them in the guides? May be they were not clean enough?

Thanks

[TrickLidz]

I think they are a press fit. I used a socket around the outside dia. to push it on...but in use, it comes off!!!

[chris steedman]

Seemshat there are no aftermarket valve seals for the old 2v heads. However i have a set of 900ss heads here today and they are not original ducati items. Just need to find out what they are


bummer
