02 7.3 burning oil

My truck started burning excessive amounts of oil about a month ago. I have checked compression (all about 400), I sent injectors to rosewood and they all checked out fine (awesome people to deal with), I sent the turbo to Barder turbo service and the turbo was fine, There is minimal blowby. I cannot figure out why my truck is burning so much oil. I had to put 3 quarts in over a week time period. I put maybe 3-500 miles on in a week. Any ideas would be appreciated. I cannot stand my truck puffing blue smoke all the time

O-rings. It is possible one got cut while reinstalling. Or you may have not seated one of the injectors quite right and gave you a correct torque but then loosened up on you.

I don't think the O-rings are the problem. I torqued the injectors down and taped on each injector with a soft mallet to seat crush washers. I have also had the injectors out and back in since the oil leak and the leak has continued.

The only other thing I can think of is, unfortunately, your valve guides are bad. You said you had good compression but that would only mean the seats are still good. When the valves open is when the oil is going in. Do a leak down check or have it done if you don't have the tools.
