Hello.. times a short question about the timing belt tension between the camshaft wheels at the V8. Had looked out of curiosity and had to notice with horror that after a service life over a night, the timing belt is quite loose and down it is tight so as it should be. Above it is very loose… After letting on the engine the strap is everywhere just not straight after longer service life! Is there possibly the hydraulic tensioner defective? The tension cannot hold correctly and the camshaft wheels are slightly twisted by the valve springs and the flap condition is created between the NWR? PS.. If after the service life, if the belt is loose between the NWR without having started the engine at the central screw crankshaft by hand 2 revolutions make that the voltage is again the same everywhere, it will then be preserved even after days. https://youtu.be/VGwmYYxPbyg Greeting Alex
