01 7.3 white smoke need help

so i have been looking into this alittle bit and i dont know where to start.
white smoke on hard accelerations, no powerloss or other big issues. at first i was thinking injectors because apparently with diesels white smoke is unburnt fuel but today i noticed after doin an oil change a couple weeks ago i had to add 4 quarts of oill ..... is my turbo on the way out???? maybe bad seals hoping you can rebuild these, so basically oil loss and white smoke here and there.

I am having the same problem, minus the oil loss. I get a puff of white smoke mixed with black whenever I rev it, or accel hard.

Oh yeah...and by the way...

If you ever think something I post is ridiculous or uneducated, just remember that I probably learned it from here.

White smoke with a blue tint to it is usually associated with bad turbo seals..

well I can tell you as im in the middle of it right not, I chased my white smoke issue for a year. Changed every part on my engine it could be related to. I will tell you one thing. Don't waste your time. buy a $10 compression tester and test the compression.. I was in denial about it. Oh its my 7.3 I babied it... end result low compression cylinder 8. I now am trying to buy a used engine and have had 12 tested over the last 3 months. all 12 have low compression on atleast 1 cylinder and these engines range fom 72K- 240k now that kilometers not miles but you get the point

It's possible to bore out that cylinder and install a sleeve, isn't it?

Wouldnt low compression cause it too run poorly, loss in power, and even bad starts?? i understand where your coming from tho, ive pretty much pinpointed my problem im sure and i think its my o-rings on my injectors, ive checked the turbo, no end play and bone dry soot out the back. and the truck seems to run 100% plenty of power. like i said i go thru 1 gallon of oil every two weeks so im pretty sure thats my problem. my only other issue/question is would oil dripping thru the seals cause my truck to blow white smoke when floored, never at low rpms jus heavy to full throttle. i do have an edge programmer.

Compression loss doesn't typically occur immediately. It's a slow loss over a period of time. You would never notice the loss of power unless one day you pulled a 15,000# trailer up the grapevine at 70, and then a year later you weren't about to get over 45.

There are many things that can cause white smoke while the engine is warm, and doing a compression test is a worthwhile thing. If nothing else, it gives you a baseline in the event of future issues.

wick07, is there a reason you can't just rebuild yours? I'm positive the machine work on yours would be cheaper than buying an unknown used engine.
