Oil weight? Temp? Engine? Miles? General condition?
Why my both cars started making grinding noise after a harsh cold start? Seems like noise is coming from engine and sounds close to timing belt area.
Cold weather tends to bring out bearings and bushings that are getting a little old. The extra clearances from the temps causes the additional noise until things warm up and expand.
My thought is that one of the bearings/bushings for a/c, alternator, etc is in marginal condition and causing the noise, and yes it could happen on both engines at the same time
Don't forget that the waterpump has a bearing as well and if you are lucky, that's buried under the timing chain cover!
