blowing smoke
Hey guys I'm a new owner of an 05 250 powerstroke. This site has really help me with regards to questions I have and I really appreciate everyone who takes the time to reply. I had an egr cooler flush done, replaced the egr valve and got an injector flush done as well about 2 weeks ago. The truck drove great now its constantly blowing blue smoke.. Idling driving warm or cold. My mechanic said its running too rich but I figured the smoke would be black if it ran rich. All forums say its burning oil. Any suggestions please

Blue smoke is oil or fuel I belive. I wouldn't drive it until you have it figured out. You could hydrolock your motor. Or the motor could run away being feed oil from your Turbo. Either case you can melt a piston or pistons and new motors are not cheap.

When i did the injector flush the mechanic said that cyl 8 was throwing a code for a compression problem, but after the flush the code disappeared... could it be an injector failing?
Also, is it normal for this truck not to engage the check engine light for this kind of thing?

You need to have the codes read again
And be VERY CAREFUl that injector that the code came up on may have cracked the tip and could be dumping raw fuel in the cylinder possible chance of hydrolock
Hows the coolant leval???

It was probably throwing a code for contribution balance problem and not a compression problem. A contribution balance problem is an indicator that an injector isn't performing up to spec. The flush may have helped clear out build up in the injector and it's now doing okay. It's also possible that the code was a stored code for something that happened many miles ago. After the flush, they probably cleared the codes and it hasn't returned thus far. It's definitely something to keep an eye on.
As far as the CEL. Not all codes force a CEL. The CEL is thrown normally for emission related problems. I'm not sure if a contribution balance code will throw a CEL. Maybe someone will post up what codes drive a CEL.

If the injctor is dumping raw fuel into the cylinder will that account for the blue smoke? I pulled out the dipstick and the oil was clean and did not smell like diesel. I don't understand this is all very new to me

Yes the coolant leval is good at the Low mark
And thhat probably ruled out a egr cooler issue
A bad turbo seal will cause black/blue smoke you would have to check the down pipe
I think its injector relaited since it popped a code for contributation

Okay, Try this.
Park the truck over night, pull the down pipe just remove the band clamp with a 7/16's deep socket, and pull the down pipe away from the turbo and look for oil in the down pipe, if there is oil that = bad turbo seal.
I say that because my truck blew a turbo seal and thats how I figured that out, BUT when it was my turbo seal it would only smoke for a few minutes until it all burned out of the exhaust.
Then again it very well could be a bad injector causing the blue smoke.
Recently a 7.3L at work, was running real crappy, with blue smoke, turned out to be a bad injector caused by lack a fuel crap in tank/filters.
My point, that injector could be bad, causing your blue smoke at all times.
Now, you said you are a new owner of the truck, did you buy it from a dealer or private seller? Depending on which and how long you owned it, I would take it back(if dealer bought) and tell them fix it.
