That’s what I was thinking. I mean it’s only on startup so my theory was the sudden turn of the engine from a dead stop might be making the belt slip and once it starts up and runs there isn’t a sudden force to it. Could a pulley or tensioner do that too?

Has anyone experienced this before? I can’t figure out where it’s coming from. It only does it at startup. Never makes the noise while running or anything only when the motor is rolling over. Most definitely is coming from the front of the engine.
