Re: Broken exhaust mainfold bolt
If it's snapped off flush then the head will have to come off. You will probably be able to get the stud "spark eroded" . It's a specialist job but will be cheaper than a new cylinder head for sure.......
In England I'd go to an engine rebuilder / re-conditioning company. Not sure what facilities you have in Poland but a lot of engineering companies heve the equipment to do it.
Alternatively a good machine shop may be able to drill it out anfd fit a "Helicoil" for you........ That would be cheaper............. But you need to find a company you can trust.
