Bus had been still for 6 weeks.

Dorve 120 km this weekend, no problem.

Parked it again.

Started it today, and then the loud noise was there.

There is enough oil on the engine.

Maybe I'll go out and take it for a drive around the block, to see it
the noise disappears.

But I tried letting it idle for 5-10 minutes, and that didnt make the
noise go away.

I do not like this...........
