1./ On my Dodge Neon, SOHC, 2L/125KKm, during first cold morning (-14degC)engine oil pressure light went ON after 10 min. driving. Return home and left engine to cool. Restarted the engine; Oil pressure was good for 4 to 5 min. then pressure light start flicker (app. 20 sec) and went ON; increasing engine speed to 50% oil pressure light went OFF.
- Engine Oil level is OK,
- Oil is new W5/30.
2./ 2 or 3 days after the weather was warm (6 to 7 degC)and I was driving the car 350 to 400km everything was OK !!??
3./ Now it is cold again (below freezing point, -14C) and I have the same problem with oil pressure.
* Is it possible that engine vapor frost inside engine oil circulation system causing decrease of oil pressure or any idea what is the problem???
