Hello all. I have little question. I created swap engine from M40b16 to M42b18. Everthing is ok, but. Today a get to first test run and after cca. 20 km i began to hear crazy engine sound...
Doing it at idle, but, when i have the engine about 1500 - 2500 RPM, can not hear anything. At 2500 rpm and higher is terrible sound from engine. Next one, while driving, when the engine is in the grip is ok. Engine is silent, but, when i change the gear and pres the clutch sound is back. When engine slowing down, sound is back.
So, where is problem?
Engine working normaly, transmission working normaly, clutch working normaly. I think, problem is in the clutch... But i´m not sure. And i need to make sure that engine is not dead.
Here is video with sound.
