After 400 000 km of reliable drives the head gasket deserves and needs to be replaced, if it has to be checked and remachined do I need to order specific gasket or just use the normal ones on sale?
if they are specific, do they have special identification?


Can some one tell me what is the size of the tool for head bolts?

What is the size of the tool for the chain tensionner cap and inner ring? do I need diifferent tools?

thanks for help
