Hello dear motor fans! First of all I apologize that I put the topic in here, but unfortunately I did not find a Granada department in the forum. Therefore I chose the Scorpio forum, he was the successor of the Granada after all. Maybe someone knows the problem and can give appropriate tips. First of all the data of the engine: 2,8L V6, central camshaft with tilt lever control, camshaft drive: gears, carburetor. The problem is: For some time (if you go to The noise of the valves was always heard clearly when the bonnet was opened; but now you can hear it in the interior. Oil is OK, the vehicle was tested and adjusted this week in the Ford workshop for the valve play. But the clapping is still heard from the same place. It sounds like a sewing machine; volume is just the clapping is dependent on speed. With low rotation fences it is possible to hear the noise of the valves from the left side. I think it has to do with the valves. If the valve play is correct (according to the workshop), what else could that be? Best regards Frank
