WHITE SMOKE AND HESITATION!

Hey guys I'm hoping someone can help point me in the right direction. I just bought an 05' 350 6.0 powerstroke in the fall of 08'. It's got 105,000 miles on it, out of warranty and it has over heated on me twice now this past month. One of those times being today, right before it got hot it was white smokin real bad with some hesitation when I hit the go pedal. I shut it down, added coolant and limped it home without getting hot again but it was smokin the whole trip home mostly at idle though. I called a diesel mechanic that was referred to me by a friend and he quoted me a price of $1775.00 to replace the egr valve, egr cooler, oil cooler and flush the radiator fluid from the block too since I had to use the green kind from the closest gas station just to get it home. He hasn't even seen the truck yet and but says that's most likely what the problem is. He also mentioned I could install a bypass kit that guys are doing these days but recommended that he wouldn't install one on his own truck. This is my first Ford and first diesel and I'm trying to educated myself along the way, I've read lots of posts on this site and can see that my problem seems to be fairly common. Just want to know if what I'm being told is solid and don't want to get screwed in the deal. Any responses will be helpful so please don't be shy. Sorry for the long post but I'm new and will get down with the lingo as this thing progresses. Thanks in advance.

That sounds about right. Busted EGR cooler and it was probably caused by a plugged oil cooler.

White smoke = Water/anti-freeze. 1. EGR cooler failure with potentially associated other problems like secondary oil cooler damage. 2. Headgasket failure.
Blue smoke = Oil
Black smoke = Too much fuel/incomplete burn/wrong injector timing

With your power loss and coolant dropping it is most likely one of the 2 pesky problems. If you pop off your EGR valve you might be able to see indications of liquid in the intake, however only if it is a massive failure. Another sign is excessive puking from the degas bottle; higher exhaust pressure will flow through to over-pressure the coolant system. If you could pressurize your fluid system with the engine off and the EGR valve removed you might be able to see the water leaking into th intake. Regardless, you are going to end up removing the intake or the heads, so just ripping it apart will reduce the labour cost. Depending on your skill level, it is not that difficult to remove the parts to get to the EGR cooler and oil cooler. Once you have these off, the heads are not much more work to remove, except it is difficult to get them off and on without raising the cab or removing the engine. Since you are already there, removing the heads and inspecting the top end is a good plan to see what other problems that may be waiting for you. It would be a shame to fix one problem - put it back together, then have to rip it apart again for new headgaskets and/or studs. It would be a worthwhile investment in your time to keep going and replace the head-gasket and studs. If there was initial signs of impending gasket failure, having the head checked for flatness and warpage would be a good idea. 03-04 model years are the problem childs. Usually the 05 and later are better builds with less service issues than the Cummins.
