Killing Mosquitoes-Big Smoke

Killing Mosquitoes-Big Smoke

No problems 2003 6.0 6 speed w/ 93k miles except changed injectors in 2009 at 64k miles. Noticed slight loping idle one time that cleared out after WOT thru gears. Began slight smoking and stumbled a few seconds during WOT run but cleared. Smoke worsened to black turning gray at WOT and gray(?) at idle. In addition to tailpipe smoke a bit on the driver side up from the hood.

Power is ok, no pressure in the coolant bottle and no check engine light.

Pulled turbo suspecting oil leak from compressor to the exhaust side to reveal black soot but not wet on exhaust side. Shaft play side to side and up and down does not seem to be excessive. Turbo drain tube is clear and no apparent blockage at the crankcase vent tube. EGR valve is dry with light black soot.

Can anyone refer me to a copy of WSM Section 303-04D to check turbo oil leak?

Checked battery and FICM, KOEO 13.48v and 48.6v respectively. Plan to clean or rebuild turbo if warranted, delete EGR cooler, replace oil cooler and add coolant filter.

What other likely cause of heavy smoke?

Thanks

Whats the final color of the smoke.. and what does it smell like??

Does it smell sweet? If its sweet, your burnin Coolant. If it smells like diesel, you've got raw fuel coming through.

Or if it smells like oil.. Well you get the point..

You say power is ok, But are you building boost like you should on a WOT run? Do you have any noticeable soot build up around the turbo, on your inner fender/hood or any other parts in there. Maybe you've got a boost leak..

Exhaust leak, torn/ loose cac boots, dirty egr valve, and/or bad injector. Do you have a monitor....Write Up: Monitoring the 6.0L PSD.

Thanks guys, gives me a direction after I put it back together.

Any thoughts on a full flow coolant filter vs. bypass?

Wow, I think I posted a link. That doesn't make me some kind of technoid metrosexual does it? Not that there's anything wrong with that.

Off to read the monitor thread.

The ipr is the best on the market, depends on your budget and how bad your system is already imo. Any one is better than none. I have the xdp bypass coolant filter.

Thanks, should of searched before I posted. Lot of info there so off I go.

At the risk of making the same mistake again, would you consider their EGR cooler delete the best also?

are you running a tuner?

also, be sure to allow turbo relearn once running again

Ebay, custom diesel egr delete $105. I just ordered one, I didn't need the uppipe. Stay away from the two piece design.

No tuner, does the turbo relearn by itself? I've had the Recall 06E17.

thanks

What do you mean by "two piece design"?

Above you mentioned a possible cause of the smoke as a bad injector, would that be sticking open? The ones I replaced previously had a cracked tip and much more dramatic symptoms, loud knock and black smoke. Any way to check injectors without going to a shop or dealer?
