Strange Engine Noise

[Carvin Marvin]

I am posting this poser for you guys that like to ponder. W-22 01 35R Southwind. Yesterday a 90 mile run at 55mph and a 10 mile run at 30mph to the CG. After registration my friend started the engine and there was a loud noise that I related to a bad bearing in the idler or alternator or tensioners, as well as hot insulation smell. I removed the belt and spun all of the rotatable items. No noise or roughness in any of them. This AM we brought it up to temp and did a 5 mile run. Alternator was putting out 14.2-14.4 no codes, no noise, no smell. Checked around with an IR temp gauge and a piece of dowel, all very normal. So I don't have a clue. 300 miles tomorrow so we shall see.

Did you check AC compressor clutch? I don't know why but seems every problem I've had w/them started as an intermittent (tho didn't stay that way long).

[Carvin Marvin]

Yes the clutch pully free spun, no noise or drag. Thanks

was your engine run air conditioning turned on at the time? if so, the compressor could have stalled and the serpentine belt slipped on the pulley making the burning smell.
