fzr valve stem seals
so ive been leaking alot of oil from that black box behind the engine (not sure what its called) dealer keeps telling me that im just putting too much oil but IM SURE THAT IM NOT.. while out riding out here i ran into a well known jetski mechanic in miami and he said that my valve stem seals might be bad or have gotten loose..
so is this possible? does it make sense? has anyone seen this before? would this be a DIY job?

Possible, but not likely. Is the little hose from the bottom of the separator (black box) to the block connected well?

What mods do you have? excessive "blow by" can happen when you run "High boost" or your compression rings are leaking back into the crankcase.....and too much oil will cause the problem. Have you ever thought about a catch can? or the Riva crankcase breather mounted high above the valve cover?

update: took my ski into riva this morning.. they were absolutely dumbfounded.. well i just got a call from the mechanic saying that the seals from the supercharger got bad and was leaking oil into the crankcase and was what caused the oil leak into the hull.. they called yamaha and they approved a new brand new supercharger and everything that comes with it.. my jetski was just put back together and is ready for me to pick it up..
