04 Issues thinking headgasket

[Mikeh1725]

Welp things aren't looking so bright for the 6.0 as of late. While back I did new oil cooler, coolant flush, ELC coolant replaced and blocked off the egr cooler. So I drove the truck back to D/FW (250 miles) where it sat for 3 weeks. Coolant level fine at this point.

Anyways, I drive 5 miles to work just fine then drive back home and check the coolant level... It's higher than before in the degas. FRICK@!#@!$#@!

Next day, same routine but coolant level looks higher than yesterday (Not puking at this point but doesn't have much room left in the degas) Double FRICK &*$#%^@!

Guessing Headgaskets are an issue now and thoughts or advice?

Truck drives fine just concerns me with elevating coolant level. Also, I pop the cap off and it has some steam like stuff coming out. No oil in coolant that I can tell.

Now when you open up cap does the coolant level drop down when pressure is released?

Keep a eye on it, my truck has different coolant levels at different times. Everytime I go up to the mountains the water level climbs and so does pressure, when I release the pressure level goes back to the line.

Watch it for now also check the oil level closely and see where it goes. Without checking the cooling system pressures or testing for gases you have to observe levels over time if your introducing oil into cooling system it will show.

When I release the pressure the coolant level rises. Will check oil level in the morning.

Does it settle out or stay high?
If it's climbing obviously it's being filled from fuel or oil, may want to give it a sniff in the morning.
Do you have guages to monitor coolant/oil temps?

My 06 does the same thing of it's not completely warm...around 135-150* the coolant will rise...but when I release the cap it settles back to norm

Checked this morning and before I left work and the coolant went back to normal. Did add about a quart of oil, but I knew it would be low considering the rear main and front main seals are leaking on the motor.
