Hi Steve, I've had this problem before, and in most cases I solved the flickering or flashing oil light with a thicker oil, like 20-50 wt.

>My oil light will start blinking on and off at a regular fairly slow timing and no changes in engine speed seem to affect the blinking.�  However when the engine is switched off and restarted, there is no oil light.�  However after a few minutes, the regular blinking starts again.� And once again, the speed of the blinking, on-off,on-off seems to be completely unaffected by engine rpm.� �  My gut feeling is that its not oil pressure or lack of that is causing this but some other fault.� �  Engine is a 2.1 from a Syncro I think and its installed in my 1989 Bluestar Vanagon.� I am unsure of the mileage but was told its a little over 100k.
