blue puff of smoke once in a while
Ok right after I got the tog back from the re-gear (as in when I left the parking lot) I had some oil smoke pouring out of the exhaust. Found out that they service tech did in fact drive the piss out of my rig (up near red line in first gear and then let it engine brake back down to idle over and over again for five miles to begin the break in) even though I never authorized it. Well now that I've put about 1200 miles on it I noticed I get a puff of blue smoke every once in a while (maybe one time out of ten from a start) and I'm starting to get concerned. I'm hoping its just a valve seal and not an indication of rings damaged. Thoughts on what I could check? It's a 22re with 239k on the clock and it has NEVER burned any oil before. I used/burned almost a third of a quart in the thousand miles we did over the last two days.

Not to get you worried, but when mine started that, it was the beginning of the end..
Mine is a 3.0 v6, but symptoms could be the same...
Mine would just make a little haze every now and then. This went on for about a year.
Then one day after a long highway drive, I came to a light and when I went to go again, I smoked out the entire intersection...
Got lots of opinions on what the problem could be and everyone said rings, not valve seal....
Nope.... Not rings, not valve seal.....
Burnt exhaust valve..... A hole right through the valve....
Check your plugs and do a compression check..
At least yours is a 22re and it will be easy to pull the head and fix....

My money's on valve seal. Hey, it's $12 and an hour or so of work to find out, right?
Mine started doing the occasional puff of smoke on takeoff at about 225k, also used about a 3/4 quart every 1k miles. Replaced the valve seals, no more smoke and oil consumption is down to 1/2 quart every 3k.
I didn't pull my head, I did the compressor trick to keep the valves from falling out. I pulled the head bolts, removed the cam, then put the head bolts back in with some spacers I'd made out of conduit line (any pipe of the right diameter would work though.) Then make a compressor line adapter out of a compression gauge, and away I went.
Side note: don't drop any of the valve keepers. They go straight down the oil return passages. Don't ask, don't ask...
