M20 885 valve guide suppliers/sizes

[14thirty]

The company that is meant to be working on my 885 head say they can't find replacement valve guides.

I see they are no longer available from BMW.

Bimmerheads do them https://bimmerheads.com/products/m20-st-guides with 13.25 mm OD.

VAC do them https://store.vacmotorsports.com/vac...m20-p1659.aspx with a choice of sizes.

ECStuning seem to do two sizes https://www.ecstuning.com/b-canyon-e...121267676~cae/

Where do you usually get guides from, and how can Bimmerheads only sell one size? Which is 0.25mm oversize going by RealOEM https://www.realoem.com/bmw/enUS/sho...diagId=11_4377

Yeah that's what I wanted to do, but they've been sat on this for months with no progress.

It's weird what your brain retains- "Canyon" brand, probably from Asia,
have worked in past for me.
Rockauto?
oh- I see they only have ITM (certainly China, possibly fine) now.

If you get the first oversize, the head can be reamed to fit.

Like Digger, the ONLY times I've messed with this is on el cheapo home shop rebuilds
where it's more fun to do it myself and 'save'- for anything serious, the machine shop
has far better resources than I do.
