1987 BJ70. 3B engine. 467,000km on engine. In recent months I have noticed low oil pressure during startup. It has been slowing getting worse in the past year. There was nothing that really happened, I have just become more and more aware of it recently.
The needle hangs at the bottom for 5-15 seconds at times before it rapidly moves up to normal. Oil pressure is fine when running and I have not seen anything unusual except at startup. Last week the engine actually shut down as it registered low pressure. This often happens to me on the re-start after changing the oil.
So I need some help -- where should I look for the cause and remedy?
