Valve Timing Adjustment Actuator *A.K.A* Cold weather start problem

[bcredliner]

You probably know that the colder the weather the more likely you will hear a clatter when you first start an engine after a night of sitting because the oil takes longer to get adequate oil pressure to the engine. Since it is fine in the summer I would change the oil and filter and use a 5-40 wt. Mobil 1 or because of the extreme cold area you are in even 0-40. That will likely cure the problem without adding any other products.
