TO-35 has oil coming out of the spark plug holes,fouling plugs and smokes whitish smoke all the time. I checked the compression and this is what I got 85-90-85-90, i"m thinking valve seals are bad but I am open to suggestions before I start tearing it down.It"s a z134 4cyl gas engine. Thanks
 
My guess is that you have some bad oil rings. If your luck is like mine you can go ahead with an engine job. Good luck.
