Hi together, have the following problem and need help.. so I drive an e65/735 petrol engine with gas.In idle mode the engine runs relatively quiet; however, when the 7th and 8th cylinders are speeding up, they no longer work with… or then I am shown ignition oscillations on these two cylinders.As a further error is the tank fan and sporadically the crankshaft sensor in it. Today I take off the valve cover and take off the bearing block incl. intake camshaft and eccentric shaft ut. Everything looks good and both shafts show neither inlet tracks nor any other damage to the cams. Intermediate and tilt levers also look good and have not entered. So, now to the curious: as soon as I pull off the adjustment unit of the Exzenbershaft the machine runs silky soft..at all speeds.Of course without power…but it runs quite quietly.I think because of this, I can exclude damage to the head and the valves. Who knows advice and has an iddee, what npoch can be responsible for the ignition oscillations? Thank you in advance
