doubt theres anyhting wrong with your engine its the pcv system I have the same problem as you do.When your pistons are moving up and down there filling the block up full of air and your pcv system cant handle all that air so the air has to go somewhere.mine finds its way out of the dipstick pushes it out and squirts oil on the motor and the best part is it also found its way ouist of either the rear main seal or the back of the oil pan cuss after I run its coming out of there also.you need to put breathers on the valve covers sam suggested a pcv for a toyota supra turbocharged those are soppuse to allow more air to escape.A few of these guys in here built there own little oil oil catch can system for about 20 bucks out of pcv pipe from home depot I thouhgt that was pretty cool.Anyway its your pcv system not letting nuff air out of the crankcase.good luck

 

Sure I can install a breather on the passenger side but the driver side head cover does not have a oil cap.
