re: Houston Mechanic Reccommendation? - 2017 Chevy 5.3 ticking

Please keep us updated and good luck. Like I said, in my situation, the heavier oil did the trick for me. I did want to clarify though. I have been using the heavier oil now for about 175k miles. Before and after that I have had a constant check engine light on. Light has been on for -15 years. I’m the kind of guy that doesn’t care about a check engine light on as long as the truck runs fine and is reliable. Hell my truck is 22 years old now. Like me ( I’m in 50’s) it’s tired with aches and pains every day. A friend plugged his code reader into my truck, because he was interested , a while back and it was lots of codes including three cylinder misfires. Lol. Truck runs fine so I could care less about the light. I’m now curious how many miles I am going to get out of this engine… 500k????
