Hi. Regarding the problems of blowing seals (viz., the previous post regarding using IPD's Rear Cam seal plate), does anyone know what magnitude of pressure is encountered when the flame trap is clogged? What does it take to blow out any of these seals?
Thanks, in advance.

    With a plugged flame trap, the crankcase pressure will be in the range of 2 to 20 inches of water, more or less. Maybe even more. Much depends on other variables, such as mileage, wear, blow-by. A sure sign of a plugged ventilation system is weeping engine seals front and rear.

    A good B230F engine with a clean ventilation system typically produces about 2"-3" of water vacuum at idle. A worn engine, at bit less vacuum at idle.
