when i start my 3.4 dohc it smokes. i installed a new pcv,checked all vacumm to make sure it was clear, but noticed a lot of oil in the intake. was told it needs valve seals, but why the oil in the intake? i cleaned it out with carb cleaner, and she ran clean for awhile, then started to smoke at start-up again. is it my vv.seals or rings, or both. runs great....lots of get-up, idles smooth, basically runs like it should????
