I bought 2 new Chevy engines both started to have a rod knock.
One was a create 350 for my truck.
The other was a factory ZZ502.
The reason for the engine knocks, I am old school so I thought the thicker, was better so i used Kendal GT1 racing oil 20/50.
It turns out that modern engines a have tight clearances, so the thick oil did not get to all the moving pacts.
So now I only use factory recommended synthetic oil.
