 Is this a really low mileage car? Yes. And it could be a broken valve spring. Yes, it's only 5,000, 6,000 miles. Well, if it's got that low of miles, it may just be a stuck lifter. Yes, I see. The first step I'd try before I even take the valve cover off is going to find some Justice Brothers. There we go. That's where I was going to head to. Engine tune-up is what they call it.
