2005 magnum question help


#1

2005 magnum 2.7 L: time chain tensioner was making loud noise @idle last winter and it stopped during the summer.
Again it is winter time and the noise is also here again.
Do you have any suggestions or see any correlation of the cold outside temp and the noise?
thanks.

Using the recommended oil viscosity?
Has the oil been changed on time and using name brand oil filters?
How many miles?
