Hey guys, New to the forums here and I need some help. I have searched the internet high and low to find my answer and cant seem to come to a conclusion. My engine is in a JD riding lawnmower and is bellowing out white smoke that puts a space shuttle lift off to shame. I have run several tests, so Im going to list them real quick: Compression check - both in the 150psi range hot. Leak Down check - both in the 20% range at TDC compression stroke. Oil at proper level. No gas smell in oil. Adjusted valves to factory spec. Was able to blow through the crankcase breather tube without issues. With all of this, this is what Im seeing.....when I removed the valve covers, oil was pooled up in both of them. I even started the engine with the cover off to see where exactly the oil was coming from. Almost looks like the valve stem seals have gone out but it leaks bad. From what I have read, if this was the problem, it would only blow smoke during startup. With this being a v-twin, I can see something going bad on one cylinder, but both? Its a 2005 with 320+ hours on it. The engine runs surprisingly well despite this. Just massive amounts of white smoke piling out of the exhaust. There was also a consistently oil soaked plug on one cylinder. If anyone has had this problem or can help, I would be really grateful. Thank you in advance.
