found some white chalky stuff on the inside of the hood and around the plastic resevoir you add antifreeze to.

What could be causing this?

I'm on a 6 day trip with my family and fifth wheel. Do I need to get the truck to the dealer right away?

It could be flash boiling your coolant in your EGR cooler or bad headgaskets. Start with a new rad cap on the degas bottle. It could be bad as well. Is the coolant overfilled? It should be at or below the Min. mark.

I'll get the cap today.

Coolant level is below min line, so I should probably pick some up.

Won't the enginr run funny if the head gaskets go bad? She ran lke a scalded dog on the way down here.

Dont add any coolant. You want it at or just below the minimum line. The engine will not run funny. My truck pulled great with blown headgaskets. IT slowly gets worse as exhaust gasses enter your cooling system eventually causing it to overheat leading to many different component failures.

The coolant passages in your EGR cooler may be plugging up causing restricted flow. When this happens the EGR cooler gets too hot and causes the coolant to flash boil. This increase pressure causes coolant to spew out the degas bottle.

If you find that your headgaskets are bad, do what I, and many other have done, and get them to install ARP headstuds. Also make sure the EGR cooler and oil cooler are replaced. Then add a coolant filter.

Forgot to mention: Clean up all of the white coolant residue. Go pull a heavy load up a grade and see if it will still puke. If it does not then your degas bottle may have simpley been overfilled.

Well let me tell you like the Ford guy is gonna. First, your Degas Bottle was too full. Next your cap wont hold pressure(althought something had to have breeched the cap first to ruin it). Next, maybe we should replace the Degas bottle or sand the threads with an emory cloth. After that, it has to be the EGR Cooler, right? Ah damn.....well then lets just replace the Oil Cooler for the hell of it.........

Oh well, you were right Lee(StrokinTiger), it is the damn head gaskets.

Dont let them tell you they tested for head gasket leaks, blah blah blah.......it is the head gaskets on every one of these trucks. Are they able to keep band-aiding the symtoms on some truck and never replace them? Yeap, but the TRUE UNDERLYING PROBLEM is head gasket failure, due to the bolts stretching.

Okay, rant over.

Tiger is absolutely right. Mine followed his scenario almost exactly on my bone stock 07. They finally did replace the head gaskets. They wouldn't do studs as it would void future warranty. They did however, give me the 21 point, 7 year warranty for my trouble. In one month I went from degas bottle cap to headgaskets.

Your dealer should be able to test for combustion gases in the coolant...easy test. If it's negative, then most likely coolant passages in the oil cooler clogged, causing overheating of the EGR cooler and subsequent failure of the cooler. Your dealer should be examining your intake for the presence of coolant, which would indicate a bad EGR cooler.

There are prescribed steps for determining which component failure you may have. If your dealer doesn't appear to be following these steps, find another dealer.

 

[traildog]

Well, I cleaned up the white residue before heading for home and on the way home it up-chucked again. Never over-heated.

The level is down to 1/4 full in the degas bottle and the CEL came on, but she ran like a scalded dog on our 1200 mile straight run from Florida.

I'll take her into the dealer tomorrow and let you know what happens......

Thanks for the help......

On edit: I trust my dealer's shop. They have always treated me well.

Im gonna have to suspect headgaskets then.

Get that guy studded!

Well, I got a new EGR Cooler, oil cooler, all new hoses (per Ford's reccomendation) and won't know until Monday if the head gaskets failed.

My dealer will not install new studs. He says Ford will void future warantee if they're installed.

I don't know. But I do know that I'm disappointed..............:icon_rolleyes:

 

[Smiley1]

I dont know about voiding your warranty... my dealer has them in stock. Never told me it would void my warranty. But then again, they also told me they never had a truck return for headgaskets after the ARP's.

You might want to invest in a coolant filter. If it is the Oil and EGR coolers, this will keep them from plugging up and failing.

Keep us updated.

I hear more about the missdiagnosis of head gaskets than anything else.... The egr and oil coolers cause the problems when left un addressed then it gets the head gaskets.... The tty bolts are not as good as studs but usually one of the coolers causes the problems.

 

[traildog]

:thumbsup:Well, she's fixed (for now).

New degasbottle, cap, all hoses, radiator flush, oil change, oil cooler, egr cooler, heads checked out good. Tech said something about "less than 5lbs variance"

Not sure what that means, but I hope the truck holds together!

Thanks for the help and suggestions....:clap:

 

[Smiley1]

Thanks for posting back the update. When you say the heads checked out ok I am assuming that they did not replace the headgaskets. Glad you are all fixed.

Yea, they said they pressure tested the head gaskets and there was "less than 5lbs variance". I assume that means they were within specs, but, I'm no technician........

Step one and two complete........now it will be head gaskets........sorry to be negative......just being real.....

So you think I need to take it out and run it HARD befor the warantee is up?

Absolutely!! Put the heaviest trialer you can behind it, and run it hard. Every time you stop, put it to the floor on take off and don't let up til you have too. Keep it in "Tow/Haul" mode too.

The Ford Service Bulletin actually instructs the diesel tech to run it "WOT" for several miles after making those repairs, just to check for burping again. WOT=Wide Open Throttle.

Mine did great after the new cap. It did great after the new egr cooler. It did great after the new oil cooler and hoses. It did great after the new bottle. BUT, each time.....AS SOON as I put my trailer behind it.....the burping started back.

I'll hook up to the camper today and give the truck a workout!
