Volvo Repair: smoke (pressure) from the dipstick, air intake hose, flame trap

Question
Hi, I have a 1994 volvo 850, pressure  and smoke is coming from the dipstick. I heard the flame trap may be clogged. Where is the flame trap located on this model. And also what could be causing this problem.

Thank You

Answer
it could be a clogged flametrap.the flame trap is located on the side of the air intake hose which attaches to the throttle body.be sure the vacuum hose is not clogged also.it is inside a plastic holder on the side of the hose.the holder turns about a 1/4 tunr torelease it.
