“Knock in 5.7 g.m. Motor with 60,000 miles. I was told this is a common problem and it would go away after the truck is started cold this is normal. How can this be normal? How can GM get away with this? I bought the truck new in 1998 and have all the oil change records at every 3000 miles. Now around 70,000 I will be looking to put in a new motor. Is there any place I can go for help on this problem and do you have other complaints?”
