So i got this lt230 today for dirt cheap and it runs but smokes out of the exhaust and out of the manifold where the exhaust meets the head. I was told it was the piston rings, I took the head apart and the cylinder and piston and the valves look to be in greatshape, I can't tell if the piston rings are bad or not, I'm not sure what to look for. Is there anything else that it could be? Its also leaking a ton of oil where the exhaust meets the head (what's that called?) and the spark plug is about as nasty and black as i'veever seen one.I don't know what it could be besides the rings and i can't tell from looking if theyre bad or not. any ideas? Thanks for the help!
