the turbo 5.3 died

Good idea. I think you should be running br7ef's

Running tr6 right now, what's the difference?

[o2camaross]

Just a step colder and non-projected. But slap some plugs in and scan that thing. I don't see how you could've hurt it on 10psi unless your tune was off

Update , on every start up the truck struggles to idle and blows blueish black smoke everywhere . You can rev it up and it will quit smoking and clear up. But as soon as you kill it and start it back up it does the same thing.

Might be valve seals maybe

We can't find anything in the tune but on start up it is pig rich, 10 on the wide band.

Hmm mine is funky on startup but prolly bc my roommate and I don't know know how to idle tune. It running rich would explain the rough startup but idk about the smoke. Is it blue smoking on startup or just black smoke? Could also be bc you have a dead cylinder but compression wasn't too bad. You put new plugs in?

[jansen]

New plugs, I'm thinking its fuel probs. Its black smoke so bad its killing the shit out of my grass every time I park it somewhere and start it up lol. It surely can't be tune related since it was fine before..... ?

[o2camaross]

Man idk. Hopefully somebody can chime in

+1 Sounds pretty typical valve seal issue on start up.
