When I start the engine there is a whining or whinging noise coming from the engine. After warmup it mostly stops. It is pretty loud. Any ideas what it might be?

 

Did you just change the cam shaft?

 

Is it the FXLR you are talking about? I always read a cam shaft bearing that has gone south makes a whinging noise, but I never heard it myself.
If it is, take care. In no time the whole bearing is gone and the cam shaft start eating away your engine casing.

 

Is you wife/girlfriend/significant other on the back?

 

If no recent cam change, then yes, cam bearing giving up the ghost. YD

 

 

Thanks everyone

 

On my '99 Evo motor the "whining noise" I thought might be coming from the inner cam bearing turned out to be coming from what was going on at the other end of the cam. It rides in a bushing on the "outboard" end. That was where the wear was happening. The bushing was loose in the cam cover and getting "wallered out" ( sorry for the technical term, but that's what we call it down home.)
