Mine is washed and perty on an engine stand . The motor has about 65k miles on it . I took off cam cover and minor rusties have formed on lobes, steels wool extra fine should do the trick . No metal shavings or broke piston pieces in the pan . The head is coming off this weekend . I expect to find some rust on the pistons, at least that is what the spark plugs tell me .I am going to port & polish the head,test valve springs, do my own multiangle valve job . The cam chain looks a tad loose . I am sticking with the stock head gasket sorry can' swallow $300cdn for an HK$. I figure if the stock gasket blows I better rethink my plan to lower detonation . I think I am going to mirror polish intake and cam cover .
