Lifter tap and rod knock

After reading some posts on rod knock and listening to some videos I'm almost positive I have a rod knock and I know for a fact I have a bad lifter. And I just went to change my oil after only 2500 miles and found out that I burned 2.5 quarts. What does everyone suggest to do at this point? Rebuild, replace, swap, or just let it go for now?

It's hard to imagine that you burned 2.5 quarts in 2500 miles and never noticed and smoking. And I'm sure you would have noticed a leak. I know that's not a lot of help, just an observation.

It's not that hard to drop the oil pan and see if you ahve any rods that are sloppy on the crank.

I drive on the right side, what's wrong with you?

That's what gets me, no smoking and no dripping or oil on my block. The only thing I've noticed in the past week was a slight oil smell on the highway everyone in a while which is the reason I decided to check/ change my oil before 3000 miles

Have you pulled the plugs and checked for oil contamination on any of them? You should see something by looking at the plugs if you are comsuming / burning a quart of oil every 1000 miles. If you do have a rod knock you won't be burning oil too much longer before things go south. If it has been noisy for a while it's most likley valve train related. I hope it's nothing too serious.
