2008 Chevy Silverado LTZ/Z71 1500 Crew Cab, 5.3 V8, 4X4, 170K Miles
This is my friends truck. He helps my cousin and I do the charity OCI's. He drives this truck to work and back, 208 miles round trip, 5 days a week. He bought it used with 150K miles on it. The front end was totaled and he bought it from a State Farm insurance auction. He is an excellent paint and body tech. and rebuilt the whole front end, painted it, and had it back on the road in less than 3 months. The truck is beautiful and looks as if it were never wrecked.
Just recently the engine started making a ticking sound from start up to operating temperature. He and I both know it's a lifter, but he don't want to go into the engine JUST YET. I am trying to help him figure this out without having to start pulling the valve covers, etc.
What I was wanting to do was start with the oil and filter. I have 6 qts. of Castrol 0W40 oil that I was going to use on my next OCI, but was going to ask here if this oil, along with a 32 oz. bottle of MMO, would be a good starting point. In the past, I have used all kinds of weights of oil along with MMO to fix this kind of problem with these engines. I think there's a little debris in one of the lifters and just want to know if the Castrol 0W40 oil would be a good candidate in this engine, even though it's spec'd 5W30? Opinions please?
