6.0L Noise

i got an 04 F350 blowing white smoke. im leaning towards EGR Cooler for that, but the my main problem is a high squel under load ie. climbing trailer up a mountian and the engine temp rises. I have a p0299 tc/sc under boost,
p0470 Exhaust Press. sensor, and p0472 ep sensor low. Am i looking at a turbo porblem or could it be the fan clutch?

I don't think it's the fan clutch. I'd check all the turbo hoses/pipes for a crack or split including the ones from the exhaust manifold's to the turbo (metal flex joints). If you're blowing lots of white smoke and you suspect the EGR cooler then the high temps could be from losing too much coolant, so check that first. These problems are all related in one form or fashion. Sounds like one of our tech's needs to chime in for a professional opinion on where to start.

You may be good to go since it seems that the EGR cooler was bad. If it still does it once in a while it may be the cap not holding enough pressure. A bad cap can give you a tea kettle whistle.

When the egr cooler fails it will send coolant through the exhaust side of the turbo. This liquid in the turbo can make it corrode very fast which can cause turbo noise. Hopefully you can clean the turbo and dont have to replace it.
