tea kettle noise under load???????

[at0075]

Got this crazy noise when i put my truck under a load or kick it going a hill. When the turbo starts to boost higher psi i hear this little tea kettle fart noise in the cab and when i let off the gas it goes away. could this be my coolant system over pressurizing and releasing out of the degas bottle. i have noticed it had puked a little on the bottle but now this noise??? i have a feeling im driving down that road of head gasket and studs. about to get my gauges hooked up to read ect and eot to check my oil cooler to make sure its not flash boiling the egr cooler. thanks

If your delta is ok, then it could be your up-pipe or "Y" pipe bellows have a crack.

check your intercooler boots. i had the same problem a few weeks ago and thats what it turned out to be. the boot going from my the turbo to the intercooler pipe had slid off the turbo a little cause a loud hissing/whistling noise.

thanks guys i checked my boots and the only one i can tell is the boot in front of turbo coming from intercooler. it has some oil and moisture on it. this could be it. im goin to clean and adjust.

Headgaskets is my guess. I had that same exact sound, it overpressurizes your coolant reservoir and the sound you hear is the pressure blowing through your cap. You getting coolant residue around degas cap? Have you done headstuds?

I had a problem similar to this, and replaced my cap on the coolant resvoir and the problem has gone away

for $10 it might be worth trying first

Replace your coolant cap

I agree replace your coolan cap and if the problem is still there then you may need to start thinking about head gaskets...

First step, dont freak out and think the worst. Dig into it. Agree with above, start small. Check boots, then y pipe, then get a new cap, it is the cheapest and work up from there.

These motors really dont just blow head gaskets, they blow them because something else failed such as an EGR or oil cooler.

Had this same EXACT problem for a while. My EGR cooler was bad. Replaced it, havent heard it since. I also had the coolant residue around the cap. The cap and bottle are less than a year old but I could have destroyed the cap since I waited like 3 months before I got the delete. Im going to keep an eye on it.
