I have a loud knock at cold start up, or after sitting 6-8 hours on cold days.
the truck has over 180k miles.
The sound goes away within a few minutes. It sounds more like a knock than a lifter tick, and seems to deep of a sound for piston slap.
I am running 10w-30 Valvoline synthetic High mileage. here is a video of my truck the other morning.
thanks for any help
