Hey guys I rebuilt my 06 YZ450F last november with a new crank, piston, rings, and new gaskets. I didn't follow the torque specs in the manual and of course the head gasket leaked. There was a ton of coolant in the oil. I replaced the head gasket and base gasket then followed the torque readings. I rode it twice since the rebuild, after the first ride there was no coolant leaking and the oil looked good. After the second ride the crankcase got broken because of a chain. The bike has been sitting since November waiting on parts to fix it. I got the new cases in and when I drained the oil it had water in it, the water came out before the oil did on the drain bolt by the clutch cover. The drain on the other side of the bike had no coolant come out of the oil and the oil wasn't milky on that side. I am taking the engine apart to replace the cases, so it will have fresh Athena gaskets and seals. Come someone let me know what else I should order to fix this problem. I am guessing it has something to do with an O-ring on the right side because the coolant came out the right side drain bolt and not the left.
