6.0 puked with studs

[2005F250]

What would cause a 6.0 to puke that has studs? Mine puked really good. Sprayed the top of the motor, ABS system, fuse box, firewall, and I think the drivers side mirror. Degas bottle is dry. I still have an EGR cooler but it's blocked off. I was towing a couple of weeks ago but what part of the 6.0 system would cause that?

Im not 100% positive but I think you can still have problems even with the block off plate thats why everyone recommends to take it out completely.

Blown head gaskets. Studs are like condoms, Not a 100% guaruntee. Heads might have been out of spec or the block may have been out of spec when gaskets were put in. Gaskets puke, egr coolers blow out exhaust.

Did you have the heads checked and/or milled when they were off? How good was your EGR cooler before as well? Could possibly be the oil cooler went. Hard to say. Who's tunes are you running and how heavy did you tow and with what kind of file?

Common Causes

• EGR Cooler leaking
• Oil Cooler plugged or leaking (which elevates oil temps AND prevents coolant flow to EGR cooler
• Blown Head Gaskets from stretched TTY bolts, most likely from excessive CP (cylinder pressure)
• Bad degas bottle cap (if you are puking coolant, you should replace the degas bottle cap after fixing the root problem).
• Clogged Radiator (air side)
• Thermostat
• Some suspect a collapsed radiator hose
• Coolant Temperature Sensor
• Injector cup
• Glow plug cup
• Warped or cracked head
• Water pump fins are split where they go around the shaft

Could high coolant pressure cause the puking? And if so how would it get that high?

Never milled the heads and I think they were within spec. EGR cooler was brand new when it got studded. I was running spartans 40hp tow tune for max vehicle GVWR and I was towing 7K lbs. One thing though is when ever there is a trailer hooked up to my truck 1K lbs. or 10K lbs. the engine fan is always on. And half the time it's screaming.

I like this guys post. Thanks. I'll sniff the motor tomorrow to see if there are any diesel carbons in the cooling system.

High coolant pressure = Head gasket issue. I know several guys that have had studs put that still puke but its only under extreme load or pulling. Just one of those 1 in 100 things.

They puked and were fine? or puked and blew the HG's?
