Default smoke from valve cover breather during warm up... any ideas?

changed the oil today and i noticed some smoke (looked white) coming from the breather on the valve cover. but it only smoked during when the engine was cold. once it was all warmed up, i didnt see the smoke anymore. i tried to get a closer look but it started to burn my eyes. any ideas what the problem could be and how to fix it? here's the basic setup: b18c1, je pistons, eagle rods, and t3/t4e. lemme know, thanks.

smoke from the breather indicates increased crankcase pressure. White smoke, I am not sure about.

well if it is cold outside when you are checking this then chances it could just be the change of temp from going from hot air into cold atmosphere...

but if its warm and its doing that then i dont know... it could be your valve seals going bad., but if it is only doing it durring warm up, then i dont think you have too much to worry about.

I would start by replacing my PCV valve if I was you.

If it's cold outside then sometimes it will blow white smoke (vapor). Speaking from experience.
