I've had the same problems for the past two years in the winter. Dealer
said there isn't a problem. Once the truck runs for 15 minutes on the
highway, it goes away. On mine, it almost sounds like someone playing a lot
of spoons under my hood.
I was told that the lifters are not getting enough oil in the beginning of
the warm-up, thus resulting in the noise. I am always afraid that this is
the start of something more serious, but as I give it gas and get out of
first (auto), the pinging goes away. It doesn't come back again until I
start slowing down past 15 mph; but not after it warms up. I've had this
before and after changing the stock air filter to a custom K&N cone filter.
Anyone else have ideas?
