B20Vtec sucking oil over intake valve stem seals
Hey gents,
I´ve currently build a B20Vtec in Germany and really love the power from the car.
When tipping in WOT after deacceleration it was smoking.
Pressure and leak pressure test were both fine.
I removed the head and found, that all 8 intake valve seals are full of oil.
Exhaust side is looking beautiful without any oil.
I have a catch tank connected to the bottom end with drian back and breather attached to it.
Whats´your thoughts on that? Can it still be a problem with pressure?
Is it mandatory to have a catch tank connected to the valve cover?
