How do you fix a grinding timing chain noise on cold day starts?

[Edit]

Answer

Never heard of a grinding timing chain. Maybe your starter is dragging. Get your starter rebuilt. Check your battery voltage and alternator amp output. Check all connections at battery starter and solenoid.

Plug your car in when its cold!

That problem does exist in older Nissan Pick-Ups. Some Used Car books mention this as an annoying but otherwise not troublesome rattle of a chain that has been manufactured too large for years. So the grinding noise can only be fixed with a revised model of timing chains for a lot of $$. Apparently, the noise stems from the movement of the chain itself and not its banging against any housing. After all, it sits in oil, so I just replace the oil more frequently.
