My dads isusu trooper with the 3.2 dohc v6 makes an awful noise sort of like a SUPER loud ping anywhere above 2500 RPm. Its worse on hills and only does it when the engines under pressure, not when revving in neutral, etc. Its constant at interstate speeds and i know it cant be good but cant figure out the problem. Any ideas?
