I believe your blue smoke may be from that ccv into the exhaust mod you've made. Does it smoke blue when you first start it, or after the exhaust is nice and hot? If it's at startup.....I'd say you might have some oil leaking down into the chambers maybe from leaking "O" rings. There will be some other views along here shortly.

well both
on a cold start blue smoke for a minuite or two then stops doesnt smoke blue until you hammer the throttle down and even moderate throttle
if your easy on the throttle no blue smoke
and if you lay it to the floor and let up right away blue smoke on deaceleration
by the way 4000 miles on existing oil
i had the ccv mod done last jan never smoked then

In my humble opinnion....you may have some "O" ring issues. First thing I'd do would be to take a look at my fuel filter. If it is either black or blue in color... you've probably got some "O" rings leaking.

I agree with you though, sure sounds like the edge is getting torn on one of the o-ring. Full throttle = high HPOP pressure and more oil squeezing past into the diesel part of the injector cup and then getting injected.

well two week later my turbo showed up
got her installed fired her up
went for a drive all sighns of blue smoke gone , oil leaks gone , turbo stall and surge gone , flutter gone
that gtp 38r turbo really whines with the open element and with the exhaust before back wheel sounds pretty awsome
now i need to find a relief vavle
one other question when the 7.3 defuels what exatly happens does it restrict the flow of fuel or drop the fuel pressure when i am pushing 30 # boost i cant feel it defuel any insight on this thanks
