Spark Plug Tubes o-ring replacments availabe?
 

Since I have the valve covers removed I figured I try to change out as much as gaskets, O-rings, seals, etc as I can. My tubes appear to be fine and would like to replace the O-rings on them but I don't see BMW having this option available. Does anyone know the sizes or have changed the rings or do they just purchase replacement tubes? I don't have any oil in the spark plug holes so Im sure I can just throw these back on but as stated since Im at it I'd rather replacement if possible. Whats the time frame these should be replaced if any?

Any feedback on this would be great.
Thanks in advance.

the spark plug tube seals come with the Valve Cover Gasket kit.

Are you sure? I have the kit at home and didn't notice any spark plug tube o-rings in the kit??? I'll double check tonight

Show me a diagram I think we are talking about 2 different things here.

It would help if you listed your engine type in the thread. On 3.0 engine the seal between the spark plugs tube and the valve cover normally come with the valve cover gasket set, not unless you brought a cheap set from eBay or Amazon.

Sorry I posted this last night and wasn't thinking straight. I have a 04 4.4i.

Hope this clarifies things up. Sorry once again for not posting vehicle specs.

Oh, well then I'm of no help, I have a 3.0, lol

Its all good! I think the 3.0 do come with all seals for those but the V8 N62 have its own tubes with O-rings. Not sure if the older V8's have them or not. But looking around it seems that you have to replace the entire tube. I may double check my tubes for cracks, etc and if they are still good may just head over to a shop and find O-rings that match up and replace them. Was going to buy new tubes but Im pretty sure my tubes are fine.

Anyways thanks for the response though! :thumbup:

seals only come with the tubes, I would replace them all

I did change all 8 of mine

You replaced the entire tubes or just the O-rings? If you replaced the O-rings do you remember the sizes you got?
