Hi

Found this gunk in the 2 hoses for the oil breather and in the right corner on the cylinder head. There is no gunk in the oil filler cab, and the oil filler cab and oil stick is not being blown off.

I know that when oil and water mix like that something is wrong, i think maybe this means fitting a new headgasket, is that correct ??

If yes, how difficult is it to change the headgasket?

Do i need to get an engine setup after the gasket change ?
