After dropping out the engine and changing the O rings on the rear cylinder head its still leaking oil from that area. Is there any other reason for the leak please ? I know they all weep a bit but mine is chucking it out. I thought that the O rings would cure the problem. Its a 91 900ss. Help Kev !!!!
Its the head, the top 6 cooling fins are dry as a bone. The one on the joint is wet with oil. Why should it still leak after changing the O rings ? Operation went without a hitch. All changed over with no drama. Is there another answer? Oil breather was changed a month ago. Help
Henners...dont be naughty and go directly to the H*nda forum !!!
Kev, I didnt realise the head is only sealed using the 'O' rings - I honestly thought there was a gasket of some sort on top of the barrel.
Looking at the parts pdf it shows TWO DIFFERENT part numbers for the O rings used - could you have used wrong ones or got them mixed.
Otherwise - I'm stumped and can only think of awful things like distorted head or barrel OR perhaps your oil pressure is running too high for some reason...
