E30 Zone

Hello,

I need help and some info.

If I want to replace my valve guide there are some oversize outside diameter +0.1, +0.2, +0.3.

It is my second replacement should I use 0.0 or +0.1?

And if I use +0.1 does the in and ex valve also need oversize or all valve has only standard size?

Sorry I can replay because e30 zone prevent me or some error so I can replay I will replay my answer in main first thread.

Thank you
Markus

Thank you Reggid and kryptonite.

I need to buy for direct replacement because I don't believe machine shop here can made some precision for me so better buy ready plug and play

take the head to a cylinder head place, they will work out all that stuff for you and hone the size properly to.
