Hello to all. I have a 17 Sierra Denali with a 6.2. I am seeing alot of traffic on the valve springs breaking. So. This brings me to my question. Is there a replacement set of valve springs I can get that will work with the stock motor so that I do not have to worry about the springs breaking as they have on other engines? I know that the earlier engines have the yellow springs and the later have the blue ones. The blue ones are supposed to be the updated version, but have heard they're still having problems with them too. Thanks in advance.

There was a thread on gmtrucks asking the same question right about the time my yellow painted one broke at 120k miles. That guy had a newer truck with the blue valve springs and it still broke. If I was going to go trough that much trouble to change all the springs I would go with aftermarket one so then if you ever swap cams that part would already be done.

Even though it does happen and it happen to me. I wouldn’t really worry about it. Lifter failures are much more common
