Latest issue:

The car, '85 245 187.5 miles.

The problem, had idle problem so I cleaned the throttle body, adjusted t.p.s.,replaced air bellow(mine was cracked)flame trap was replaced 8k ago.Noticed an oil drop on idle screw, is this just blow-by or do I need another flame trap already? Car runs fine, I just like looking for something to fix.

Thanks, Phil Stone '85 245GL 187k

Hi, Phil. In 8K, the flame trap might indeed need checking and might be ready for a cleaning. Especially if you are running dino oil in your car. When I got my 245 and did the flame trap/throttle body cleaning for the first time (maybe ever???) there was oil pooled down in the air intake bellows, and the TPS was FULL of oil, I poured out maybe two capfuls worth. The flame trap, original brass unit, was a solid oil crud cake.

Since replacing the flame trap and changing to synthetic oil it seems to stay pretty dry in there. Make sure that your PCV system is really working right, and be aware that cheap motor oil (not all dino oil is bad, but...) can contain modifiers which have a lower boiling point and are actually distilling off and condensing in your air intake system!
