the pcv valve was eliminated when i did the simplification i have just a "dump tube" coming from the nipple on the oil filler neck for breathing. in any case this seems to be an irregular occurance.

I started it yesterday and there was a noticeable amount of smoke then drove it over maybe only 100 meters away let it idle while i checked the tire pressure and it was fine no smoking. (the car hadnt warmed up completely yet) then i drove it home but when i stopped at a long light only at idle i could see a waft of it in my mirrors as soon as i started moving it went away.

then on the way home i did a nice third gear pull just near my house then took it home, where i let it idle while i opened the garage to let it cool down somewhat and there was no smoking whatsoever. brought it in turned it off. so it seems to me that this is almost the strangest damn case ive had with this car. i thought possibly it could have been oil injectors or turbo seals.

Btw cars operating temp is 85 (aka 185 F)
and has never gone over that and oil pressure is where it should be

Just dont know.

To answer spindoctors question if you rev it while moving even slowly like say in first gear there is nothing, but if you tap the gas while it is already smoking in idle in neutral it will emit a much larger "puff" except if you hold it down it will clear up an go clean again. its this thats getting me. let off the gas and when it goes back to idle when fully warm it smokes.
