My silver SVX has always had an odd bouncy idle when warm, ONLY when rolling to a stop. This is most noticeable in stop-and-go traffic. Sitting still at idle, it's so smooth and quiet I glance at the gauges to be sure it's running. So long as she doesn't stall, I can live with it.

My idle is only bouncy when cold and only for a few seconds immediately after starting the car.

I don't see blue smoke so I guess that is good. Would you expect a bad PCV to pop the dipstick even if the dipstick has a new o-ring?

If I am getting oil pushed into the wrong places due to a PCV, wouldn't I see some in the end of the black air "snorkle" which is clamped to the intake manifold?
