Hello everyone,
I bought a chinese pit bike to learn more about mechanic. Well I bought the right thing, cause When I started it, it was smoking like crazy, and liquid oil was dripping out of the exhaust port.
I changed the piston and piston rings. I also changed the gaskets on my way there, and finally, I ajusted valves and made sure they seat properly.
I don't think the cylinder is worn out, but I don't know what the ring gap is supposed to be.
Now, When I start it, there's way less smoke, but still a bit of liquid oil coming out from exhaust.
That leads me to 2 questions I would like to ask:
1- could it be a broken valve stem seal?
2- about those valve stem seal, I would like to know, how does this engine lubrication works, I don't get how oil can go from the engine Block to the head of the engine, where the cam and valves are.
thanks for your help
