How many miles?If hi miles and u r going to keep the truck,replace the lifters.If it is a beater,drain the oil, get a Maz filter,replace the oil with 5w-20,put a half can of seafoam in the oil,the other in the gas tank,run the truck for 500 miles,change the oil again with a 5w-30 synthetic and see if that doesnt clear things up.BJ
