need second opinion before i rebuild engine

i need some 2nd opinions from you guys. after a short ride yesterday, i felt hot oil spitting out of the spark plug hole on the back cylinder. i stopped riding and pulled the boot off and it was covered in oil. a friend of mine said that it could be a lot of things that require an engine rebuild (rings, valves ...). i trust him but i dont want to pull the motor if i dont have to. what do yall think??

Probably just needs the o-ring or seal for the 'spark plug tube', forget what they're called.

You can use the rear axle nut to remove the tube, best to look at the manual first.

yup 99% of the time thats what it is when the o ring fails it puddles up in there and the wind sucks it out there is supposed to be a weep hole on the back of the head so it can drain there instead but they get clogged with road dirt

i wouldn't pull the engine just yet and i am guessing your friend works on american bikes more than jap bikes
