VERY strange screeching noise coming from motor.. Ideas?
I know this is an rr forum, but I'm having an issue with my f4i motor and I figured yall could be helpful.
I got a stock f4i with about 20k miles. I changed the oil 1000 miles ago.
Yesterday I began hearing a loud squealing/screeching noise from the left side (sprocket side) of the motor any time I had the engine under load. Any mild acceleration sounded like nails on a chalkboard. Even while letting the clutch out with no throttle input. This noise could be heard in any gear. The sound doesn't happen in neutral.
It can't be the clutch plates because it will happen with the clutch fully engaged & the sound is coming from the other side of the motor.
It can't be the bottom or top end of the motor since it doesn't happen in neutral.
It sounds like it could be coming from the front sprocket area, but it's hard to tell for sure.
Does anyone have any idea what this could be? It sounds like an obnoxious rusty gate opening and closing. I've never heard it before.
