Burning oil?!
Hiya, 2005 F250, 6.0, 60K miles, recently (within last 1K miles) had ARP studs, EGR delete and new oil cooler installed. Shortly after (5-6 weeks later) I noticed blue smoke under any load (taking off from red light, backing up) but not at idle or startup. Was using the "Performance" SCT canned tune after the stud install, but had the "65HP Tow" canned tune installed when I first noticed the smoke and now back to stock after noticed the smoke as a precaution. Everything else original except FICM, filters and batteries and use 5w40 Mobil 1 since new. Any thoughts?

Took it in to the shop today, family friend so I do trust them, and he says it has excessive crankcase pressure as there is lots of oil in the intercooler and piping. He says that the ultimate fix is new piston rings and he ballparked it at $5-7K. Does this sound plausible at 60K miles and no performance mods besides the exhaust? I had head studs, EGR delete and new oil cooler installed less than 1K miles ago.

Boy these Bottom ends seam to be pretty solid I just cant imagine your truck needing rings at 60K
Like Mark said some oil in the CAC system is normal
Are you the original owner
and have you been changing the oil every 5K-7500miles
At Idel how much pressure can you feel coming from the oil Filler when you take the cap off
There really shouldnt be any pressure at the oil fill cap you want a touch of Vacuum IMO Thats what the CCV system is for
Who did the studs
what kind of headgasket did you go with OEM I hope
did they mill the heads
why did you have heads done
Did you use ARP studs
See where Im going I would almost blame it on the recent work more than the Bottom end
Did it start this since the head work

wow, how exactly did he test crank case pressure. did he retest it with the cac tubes off too?
ccp can come from a bad turbo aswell.

I bought the truck with 5500 miles on it and it had no trailer hitch ever installed on it. I have used 5W40 synthetic oil since I bought it with intervals of 6K miles. The tech said that he's never seen a 6.0 that's needed piston rings at this mileage and the local dealership doesn't remember the last time they sold a set. He thinks that due to the synthetic oil and lack of use that maybe the rings hadn't seated properly? He recommended I try going back to 15W40 non-synthetic and see if it helps anything. I'll see how the oil cap pressure feels once I get the truck back in an hour or so.

I never would have thought of the turbo Cheezit
So if it had an overboost condition is that how the turbo would cause CCP??
Thanks in advance Cheezit

At 60K there probably seated the rings that is But hey ya never know
