Yeah, sorry, it fixed it. Haven't had that chirp sound come back at all.
I didn't, but a few others have. There is a plate that moves loosely and drives the oil pump. It's "looseness" is normal. You might have to use something like a skinny flatblade to lift it and make way for the balancer shaft to be reinserted. The plate is driving by the shaft which in turn drives the oil pump.Did you have issue lining up the pulley with the hexagon ring inside the motor when reenistalling the pulley
