White residue?

I just bought a 2005 6.0 with egr delete and 4inch into 5 exhaust. I popped the hood the other day and found white residue on degas and a little coolant sitting around the rim of the degas. I don't have any white smoke and I have not lost any power. Oh and when I bought the truck I did not see any white residue on the degas bottle. I guess what I'm asking is is this a dead giveaway of the dreaded blown HGs? And if it is how long can I drive it like this?

Re: White residue?

Make sure your coolant level is slightly below the min mark. If your head gaskets are bad, you can drive it till it hydrolocks. I don't suggest that, btw. Anotherwards, there is not a good answer for that. But plenty of people have done it, unfortunately.

well it could be a damaged egr cooler and clogged oil cooler and not require head gaskets and studs quite yet... I'd replace the cap it costs between 5-15 dollars and if it fixes it your all set.. mine doesn't even puke over the "new max" line but its not much over

Thanks for your help guys but it's official the head gaskets are blown. Degas bottle is puking now with new cap and temp gauge on dash goes to hot towing my trailer up hill.

There is little chance of hydrolocking these engines with simply blown head gaskets as the coolant doesn't enter the cylinders. The cylinder pressures pass through the leaking gasket and pressurize the cooling system thus causing the puking. Now if he had a ruptured egr cooler then yes you most definitely can hydrolock the engine.

He has the EGR deleted. If it is puking with the EGR deleted it means one of 4 possibilities or a combination of the 4.

1. Blown head gaskets.
2. Cracked fuel rails/injector cups causing fuel to leak into the coolant and pushes out the degas bottle.
3. Coolant level is to high in the bottle.
4. The cap is bad and needs replaced.

Do you have a monitor in the truck? I am willing to bet you just cracked at least one of your heads if your letting the truck run up to hot on the idiot gauge on the dash. By the time that thing registers it is already to hot.

No monitor just bought the truck about 2 weeks ago so buying an sct was going to happen in a few weeks but I guess I will be doing everything now!

The temp gauge just went close to the H on the gauge once and then I parked the truck. I wasn't that far from the house when it happened.

True, when it's running.
