Hello everbody,
I found today the reason why the oil pump couldn't made enough pressure the pressure got lost if the engine was standing still for a day. :-((
The oil pump has a valvet that must work if the pressure gets to high. This valve has a small steel ball, a spring and a pin to fix all. I take pressure air and blow it into the oil pump. Normally I think the valve should open about 6 or hight bar. I had a pressure under 1 bar and the air was coming out of the valve. :-((
So I remove the oil pump and take a look what ccan be wrong. I push out the pin, take the spring and have a look after the ball. But there was no ball. :-((
I meassure the borehole take another ball from a bearing and put it into the hole. Fix the spring over the ball with the pin and blow air into the pump. And great pleasure the valve works. :-))
I think some of the workers how build the pump had lost the ball and put only the spring into the pump and said okay thats all for today. What a fool!
Happy Wolfgang
