Balance Tube - Plugs

[bobc]

Does anybody know where to find fittings to plug the holes in the balance tube after you remove the pollution gear? It appears that two plugs are M10 and the other is M14. I can't find metric plugs anywhere and nothing Imperial seems to coincide close enough to use.

I'm sure some of you have done this, what did you use?

Thanks,

Best to all

I welded in an aluminum patch, the ground and polished the altered area into invisibility.

but in a pinch the right sized bolt will work.

AutoZone has small bolts for this.

You might have to order them due to the stock being 0.

Bob,

Do you remember the number of plugs and the sizes that you needed? I am trying to find this information at the moment.

Look under BSPT plugs

The threads on the manifold are BSPT (British Standard Pipe Threads).

Not sure if these are identical to the "Japanese" threads mentioned in one of the sites referenced by Enigma.

I used the commonly available NPTF pipe plugs. 1/8" and 1/4" will fit.

The thread form on the NPTF is different than the BSPT. 50 vs. 60 degree included angle on the thread but they are compatible enough for this application.
