22RE using oil

I have a 91 22RE with 124K on it, I'm using about a quart of oil every 2 weeks, there's no oil leak's on my driveway so I must be burning it, I'm thinking valve guide seals need replacing, or worse worn rings, anyone had this problem

get the head rebuilt, that way you have new valves and seals. I don't think it is the righs, that motor will last way over 200,000

Look at the spark plugs. Do a compression check. Check the PCV valve if the truck is so equipped.
