This is probably a "collapsed lifter" which is a reasonably common problem. It's not necessarily a serious problem but it can create headaches.
Lifters are hydraulic, they have a system that allows them to get taller or shorter using oil pressure and springs and this system isn't working on your lifter. It could be a piece of dirt, a bad spring, alot of reasons for it to not work.
That valve in your engine is not opening and closing properly so it will affect mileage to an extent. It could make it hard to pass an emissions or smog test. It will affect performance to some degree. It's highly unlikely that it will go away on its own.
Repairs will involve opening up the top of your engine, valve covers have to come off and the intake manifold as well so the camshaft and lifters can be got at. Lifters should be changed in complete sets, not individually and there are 2 per cylinder. A gasket kit will also be required and an oil change. You are looking at 4-5 hours of labour.
If it was my truck and I was planning on keeping it for another year or two I would fix it. If I was thinking about getting rid of it soon, I'd leave it as is and trade it now. You might lose a little on trade in value but not a lot and you would be rid of the problem.
You could try an oil additive but it will only put off the problem if it works. Hope this helps.
