I had the T/A out and over revved it. It was knocking at idle after.
I'm going to drop the pan and replace the rod and main bearings.
I'm convinced the new aluminum silicon is the way to go. They say it actually polishes the crank during operation.
I've also seen coated bearings for the 4.9 but the coating is applied over a tri metal bearing which doesn't impress me as being more wear resistant than aluminum.
