I took the head off my FZS600 to sort out a leaky valve. Stripped down the head sorted problem and reassembled. Put head back on with a new genuine Yamaha gasket. Did cam timing and checked all ok. It fired up first time and ran good for 10mins. I had a few coolant pipes leaking so I thought I would stop the engine and tighten them up. Left for 30 mins and checked the oil. Couldn't see any oil in the window so I topped up and topped up still nothing in window. Then I realised something was wrong and thought the worst. Water in the oil. I drained the oil out and it was thick mayonnaise. Took the cam cover off and it was everywhere. I assume all it can be is cylinder head gasket failure. Should I of had my cylinder head checked and skimmed. More to the point can I clean my engine out with something or is it a complete strip down?
