First off, hello. I am in the process of servicing the flame trap, mainly because of several small oil leaks in my 1989 240 wagon. I really expected the flame trap the be mucked up and clogged, however blowing through the flame trap results in smooth flow of air. I can also see through the holes in the old flame trap. Once removed and after my makeshift "blow test", I used a paper clip to push through each hole and yielded some hard carbon deposits, but no sludge. So will these small deposits that only decrease the diameter of the flame trap holes increase the pressure in the engine?

I will not drive the car again until this issue is resolved as the last time I parked the Volvo, it dumped about a half cup of oil.

I have ordered the oil separator box, o ring for under it and an entire flame trap kit(since I broke the plastic housing the flame trap resides as the flame trap seemed to be melted to the housing). Am I on the right track?
