I am always listening for odd sounds amongst the multitude of rackets my truck makes. Lately, when started cold and idling, there is a sound reminding me of a marble/pebble rattling around in a blender. The sound is independent of the transfer case engaged or not and independent of the clutch being depressed or not (me thinks not tranny/transfer case/jack shaft related sound. Bellhousing? Clutch plate? Broken rod bolt head slamming around in the block?
(only joking on the last one, I hope).
No clutch/gear change/driveability issues.
I cannot quite locate it; it seems to come from midline firewall area and is best hear inside the cab.
The sound disappears when warmed up; warm, idling, no sound. Back on next cold start.
It is too cold to have fun wrenching outside. I probably need to go listen with a stethoscope and locate it better. Any ideas in the meantime?
