I'm working on a John Deere La145 riding mower, B&S 20 Hp, model 407777, Type 0146 B1, code 080923YG, That is blowing white and blue smoke. I have replaced the head gaskets, the valves oil seal and removed flywheel and cleaned the reed valve
( it had some oil in it.) The motor starts just fine and runs realy good but smokes. It did have a bent intake push rod on one
cylinder and the exhaust rocker arm had worked loose and the push rod had dropped down,( this cylinder was not working).
I replaced the intake push rod and made the adjustments on all valves.I did notice when I had the heads off, and engine setting
for a few hours, that there was oil seeping out into the cylinder. Both did this, dont know if that is normal or not.
I did a compresson test which showed 170 lbs on each cylinder. I'm to the point of thinking there is an oil ring problem.
I did replace the fuel pump which made no difference. I removed the tube from the reed valve to the air filter and just let it hang free, started the engine and some oil did come out. That is when I pulled the flywheel and cleaned the reed valve but oil is still comming out there.
Am I to the point of replacing valves or what?
Thanks for any help with this problem
