I got a 2001 gmc jimmy with a loud lifter. At least that's the conclusion I came to after doing research. It's pretty much a tick in the engine and I believe the lifter may be sticking. So I was wondering what would be the best aproach to this situation? I am considering a engine flush but I hear so much about how it will lead to the engines death and I get that. Any suggestions on what I should do?

I used Marvel Mystery Oil, it did the job but took a while.

That works sometimes, but depending on the miles the lifter could just be worn out and need replacing. It makes more sense to do them all, if so. They are only about $50 for a set, though the labor will be several hundred, plus new coolant and oil. If high mileage and you plan to keep it a long time, it's also best to replace the cam at the same time, especially if the lifters show surface wear when removed.

People will recommend a million things that will probably work for a minute. SeaFoam was a popular option too. But I have tried them all even as recent as about 7 months ago on my GMC Sierra. the lifters just get worn or or stick and need to be replaced or at best adjusted, but its so labor intensive you can almost get the whole engine replaces cheaper. I got quoted something like 11-12 hours labor to replace my lifters in my GMC. So if you do the math on $75-90 an hour labor plus the parts..... Wasnt worth fixing.
