2000 Suburban 5.3 L engine startup knock
My 2000 suburban has a ticking/knocking noise at startup, and lasts for 30 seconds +-. I have talked to several others with similar problem. It seems to affect higher mileage vehicles more, but my neighbor has a silverado with only 70,000 on it and it has started to tick also. I am certain it is lifters, but have tried different oils to see if it would help. Does not seem to help. I am currently using 10/30 oil and have considered going heavier. Has anyone experienced similar problems and what have you done to eliminate the problem?
