Hello
I have a 1985 BJ73 with a 3B engine. 317000 km on the teller. The PO said, the engine is a replacement and has actually less km, but there is no proof.
The engine runs great. But I note since a while now on 'cold' starts (around 17-25°C / 70F) that it takes longer for the oil pressure light to turn off, than it used to. Sometimes it's even close to the low-oil-pressure emergency shut-off to kick in. I'm using that hand- throttle screw on cold starts, so revs are already raised. Oil changes didn't show any effect. I'm using 15W40 mineral.
Once the light is off, it doesn't come on again, also not when revs are lowered once engine is slightly warm. The engine runs just fine.
Any suggestions on how to approach the issue? Thanks for help
Ralf
