You answered one of my questions before regarding blue smoke from oil getting sucked into breather pipe from parking on an incline. Since then I have done a lot of checking: compression test--180# in all six cylinders; no smoking on deacceleration from hi rpm's. Car does not smoke while driving--only when it is idling or driving under 2,000 rpm's and even then it only does it sporaticly. At oil change I only add 10 qts--brings oil level to approximately 1/4 inch above lower mark. Upon checking there is always oil seeping down into the throttle body from where the breather hose connects--enough to get your fingers wet when wiping it. If I am not overfilling; not parking on steep inclines; is there any other way that oil can be getting into that breather tube? The small cone shaped reducer is still in the line at the tank end of the hose. Is a small amount of oil in the breather hose normal? I get about 1500 miles per quart of oil. If your valve guides or seals are going bad wouldn't you get smoke all the time?
