A recent occurrence, I'm getting a pretty loud rattle that sounds like marbles swirling around the bottom of a tin can. Everything else seems fine, power etc. Hear it while in neutral and idling and also while driving in gear. It's drown out by wind noise the faster you go.
Engine is a 1.7 punched up to 1911 on dual Weber 40's. Heat exchangers stripped to bare headers, new muffler. Oil pressure and cylinder head temp both normal. |

Pull the alternator belt and see if the noise stops. If so, the alt is your number one suspect.
