I just installed a freshly built new motor, all new parts inside, balanced and happy.
Runs smooth, but when the engine is revved or loaded, it develops a slight knock to it. I actually had a guy stop me on the road and ask me if my car was detonating. When the engine is at a constant RPM, it runs very smooth and quiet. I can't detect the knocking sound (doesn't mean it's necessarily not there)
This sound had existed just before I lost my crank...I had attributed it before to losing a main bearing. Now I'm not sure -
Could I be losing the knock sensor? Could it be Cam sensor? Could it be Cam Sensor positioning? Crank Sensor? All these things are unchanged since the before the rebuild. Is there a good way to go about diagnosing this?
Thanks in advance for any advice...
