bluish smoke at morning starts
my car recently started to show signs of smoke at morning starts. it's not a common condensation white smoke, it is light bluish colour. it smokes until gets fully warmed up. after it no smoke during whole day, even if it gets cold
oil consumption also went pretty high..
the engine is built with wiseco pistons and pretty loose clearances I think, but haven't had this problem before. valve stem seals were installed GSC Viton ones
any ideas ? seals went bad or something with oil rings ?

which are more or less quality valve stem seals and where can I get them ?
these ones I've mentioned in first post were installed ~15K miles ago. I doubt good valve stem seals have such short lifetime

When I had my cams installed, there was a conflict between the dual valve springs, specifically the inner spring and the valve stem seals. The inner spring was actually dislodging the valve stem seal and lifting it up, letting oil into the cylinder.

I remember seeing threads like this before where there was interference with valve springs and discussions about what seals to use. So, if that indeed is your problem, information is here.

For reference, I was running SuperTech valve seals and SuperTech dual valve springs - I experienced interference in 2 sets. Finally switched back to OEM valve seals and just running the outer valve spring.

i had never noticed the smoke color, but i was getting a big puff of smoke pulling away from a stop, and instead of smelling like ethanol, the exhaust reeked to burned oil all the time. compression test was good. english pulled the valve cover and found that four of the exhaust valve seals had popped up but none of the intake. replaced all the exhaust valve seals - smoke is gone and ethanol smell is back.
