my mates has got a zxr 400 h1 we recently noticed the oil inspection window was white checked oil and that too is white like thick milk. i presume it is the headgasket but it doesnt seem to be running hot and the coolent system isn't being pressurerised. Anybody got any other ideas ? could water get into the sump via the water pump drive seal etc.
dont fancy doing head gasket so grabbing at straws. its done 26000 k

cheers rigs

was it drained of water in the cold spell? see a thread by tanuki in the CBR section- MILK....

it is broken some way - headgasket might be the least of your worries

zxr's are really bad for misting up if used for short journeys or laid up. If its not blowing water out when thrashed and doesnt re-mist after a thorough oil/filter change it's most likely fine.

however, @26k its bang on cue for the head gasket to go.

not the end of the world though, head gasket is about £12 and its not hard to do on a zxr
