93 b2200 smoking less but still smoking

so my b2200 I've replaced the head gasket valve seals and valve cover gasket. it didn't smoke before the head gasket "blue smoke which means oil". and i though i had some stuck oil rings so i soaked them overnight and now it dosent smoke at idle just about after you get past 1800 rpm, and i noticed the plugs from cylinders 1, 3 and 4 were gummed up with oil. it has had a rebuild 50 thousand miles ago from the original owner. but the head has 225k miles on it which makes me think its the valve guides. but it seems more like a ring problem. i figured you guys that deal with mazdas more than me could give me some insight. - Thanks, Zach

I would start with a compression check. I assume you have about 225K miles on the motor? I wonder if you are getting excess blowby, which will increase with engine RPM, and that is blowing crankcase oil into the intake.

I had 165 psi on all four, and my B2200 still smoked, at 183K before my rebuild.
