crankcase oil getting in cylinder
I recently acquired an '84 spree for free and now I know why. I tried to kick the motor over and it moved about 6 inches, i pulled the spark plug and then tried again and motor oil is coming out of the plug hole. Any ideas on what is wrong and how to fix it?
Re: crankcase oil getting in cylinder
1) the oil pump may be leaking while sitting. 2) the petcock, float needle are leaking. the gas is evaporating in the cyl and leaving the oil behind. 3) someone put oil the the spark plug hole to screw with you.

Re: crankcase oil getting in cylinder
what bear? no sense of humor? leaking pump most probable. evaporated gas could happen if the motor wasnt started for a long time, but probably not.

NOT in the cylinder. In the crankcase maybe but not in the cylinder, ever.dun rite wrote:what bear? no sense of humor? leaking pump most probable. evaporated gas could happen if the motor wasnt started for a long time, but probably not.

Re: crankcase oil getting in cylinder
in that case the oil pump wouldn't do it either. does that leave option 3

Re: crankcase oil getting in cylinder
Wrong again. Once the motor is rolled over with either the kick start or electric start, then the oil will be pumped INTO the cylinder from the crankcase. Your lack of knowledge of 2 stroke basics is evident.dun rite wrote:in that case the oil pump wouldn't do it either. does that leave option 3
Oh and 2 strokes DO NOT have crankcase oil. The oil is in the fuel which is introduced into the crankcase thru the reeds, where it lubes the crank bearings and then is pumped into the cylinder to be combusted.

Re: crankcase oil getting in cylinder
since the fuel mix enters the crankcase, (the same place a leaking pump would go.) and the motor sat long enough for gas to evaporate then oil would be left over. I agree the leaking pump is the most probable, doesn't mean the other couldn't happen.
Geez wasn't looking for an argument.

Re: crankcase oil getting in cylinder
In the cylinder no. The gas and oil mix would run out the exhaust and there would be no evaporation in the cylinder. If the exhaust port is covered, the the intake ports will be closed too so no transfer from the crankcase until the motor is rolled over. Your lack of knowledge is still showing.dun rite wrote:since the fuel mix enters the crankcase, (the same place a leaking pump would go.) and the motor sat long enough for gas to evaporate then oil would be left over.

If you spout BS you will always get a response from me, count on it.

Re: crankcase oil getting in cylinder
ok I should have been more specific. It is the oil in the transmission that is getting into the cylinder, it is not 2-cycle oil! i can kick the bike over without the spark plug in but when installed I can't (too much oil and you can't compress a liquid).
Re: crankcase oil getting in cylinder
there is no way the transmission oil can get into the crankcase

Re: crankcase oil getting in cylinder
then explain why the oil coming out of the spark plug hole is gold (motor oil) and not blue (2-cycle oil).

Re: crankcase oil getting in cylinder
it is possible the previous owner poured regular oil down the spark plug hole to free the rings? since you havent been able to start it that oil would still be in there. you should definately take it apart to get a good look inside there
