Need part # for this o-ring_SOLVED_Press-Fit

Post by 86_6series »

Didn't get # 9 in the OEM gasket set, looks like it would fit.

#8 in the package does not fit, diameter too large.

Did a general Google search for "dipstick tube 0 ring" and

found rings but not for the m30 b34 block.

There's no o ring groove on the bottom of my tube.

As a matter of fact, no m30 was listed.

If I can't get a part # can a guru tell me the o ring size.

Or, do you think one of the listed rings would work for the m30--

Or, if I measure the ID of the block and OD from

the tube how thick of a generic o ring should I try to get.

Posting on Bimmerforum also.

Thanks for all & any info.

It seems to me that it isn't supposed to have an o-ring there. Was one in place when you removed it? The fact that RealOEM shows the o-ring in grey typically indicates it is not used for that model car and since your dipstick tube doesn't have a groove for the o-ring, I'd bet that one isn't required.
I've run into the same issues with my Shark.

I failed to mention that the engine builder removed the dip stick tube.

I should ask him if he remembers what he removed.

I guess I jumped the gun on posting and asking before speaking to him.

So if that's what the grayed out in REALOEM means,

I'm confused because I do have #8.

thanks for the heads up.

Thanks for all the input.

Talked to the builder and told me press fit.

So true, I'm 75 and it doesn't get better just adds more to our higher learning.
