Flame Trap Questions[ALL/1998] posted by Max on

Greetings to fellow bricksters. I've been keenly reading all the useful stuff from board contributors, especially on the topic of flame traps and the need to keep these clean or else oil leaks will result. In a recent thread someone wrote that his way to solve this problem was to remove the flame trap. Maybe this can be taken one step further... I routinely clean out (with carb cleaner) the throttle body of my 1989 model 240 with b230f motor about every 6 months to remove the crud that forms inside. I suspect that most if not all of this comes from the blowby gases which pass thru the flame trap and then coat the intake area. Can this all be avoided (from a mechanical and not legal point of view of course) by removing the flame trap and rerouting the big hose to vent somewhere under the car? I could then plug up the nipple/hole where the big hose is now attached at the throttle body side. Presumably it will be necessary to plug up the smaller hose which goes to the intake manifold orifice fitting as well. Will the blowby gas then be able to get out properly (under the car) without the vacuum assistance of the intake air in the existing setup? Will this result in a big oily mess under the car and on the garage floor and will there be a smell from all this? If this works, no more oil leak worries and no more gunk in the throttle body! I will be grateful for any (hypothetical) suggestions and comments.

My thoughts exactly (or at least similarly). Wonder why the crud gets routed through a crucial moving (stickable) part like the throttle body. It's probably necessary to get the correct mixture of blow by gasses. Legality is another thing of course. The old engines used to have a pipe off the crankase to the underside of the car. The blow by gasses just vented to the atmosphere under slightly higher than ambient pressure.

This would be very dirty environmentally. For the sake of my kids, please leave your PCV system hooked up the way it should be. If you're so worried about cleaning your throttle housing twice a year, come by Atlanta and I'll do it at no charge!
