BMW e90 320i valve stem seals

[UntamedPercy]

Good day, where can I get my valve stem seals done without having to remove the head. I am situated in Johannesburg South.

Thanks

Hallo and welcome, not sure if it would be possible to replace valve stem seals without removing the head, had heard stories about it ,never saw, will never try it either. But for interest sake, please share your experience if done like this.
