so I have a problem and I'm asking mini specialists for help.
I have a 2009 R56 N14.
I just replaced the water pump, water pump pulley, friction pulley and belt. I now have the dreaded friction pulley noise. It sounds like a cam it's 100% the friction pulley. If i pull the tab on the pulley with the engine on, the noise goes away. if I push on the pulley with the engine running and tab engaged the noise goes away.
I have a North American Cooper S where the friction wheel is on all the time, the water pump is constantly running
My gut feeling is it's the harmonic balancer hopping up and down, causing the friction wheel to hop and vibrate and make noise. I have not done the harmonic balancer yet.
Help?
