Hi!

I've been running an N53 head on my N54 which I'm currently in the process of rebuilding.
Especially the exhaust valve guides are worn and no longer good, but might replace inlet guides as well.
I've been trying to find a good part number for these guides for N53 (I'm fairly sure N54 are the same), but without luck.
Nothing on realoem from what I can find.

Only thing I've managed to find is some TRW guides with ean 4028977876875, but I would rather have a bmw part number to search for (since I found alot of vendors has inaccurrate part info).
I was hoping someone might have insights into where I can find good oem quality guides, I'm based in the EU.

Thanks!

you can't order these from the dealer as you already found out.
If you are based in EU as well, I would suggest to order them at Subi Performance or HCR Latvia.

This confirms my suspicion.
HCR built my engine initially, so I'll reach out to them.
Thanks!

Eventually my local machine shop found some guides with the correct dimensions in their assortment.
