signs/symptoms of blown gaskets?

NCPowerStroke · May 2, 2013

well i popped my hood today, to chang the oil. and i noticed my trucks coolant bottle has been puking. there was dried coolant on the battery, air filter, bottle, etc....

any how i know thats a sign, but i also had my bottle filled to the max line.
it runs great, hasnt missed a beat *knock on wood*.
but can you guys tell me what exactly i need to look/listen for?

First don't fill to max line. That's actually over full. Fill to the min line.

Now verify you EGR cooler isn't the route cause.

What u need to do is verify your fan clutch works, verify your ECT and EOT are in range.

Test your cap and make sure it vents between 13-16psi

Install a pressure gauge in your coolant system and see how much pressure it builds. If it reaches the pressure at which your cap vents then its head gaskets

went out side a few min ago to start up my truck...

cranked and held key...no start
second time cranked and held key...no start
3rd time it finally started

looked in my coolant bottle..its almost drained
i have 1/4th tank of fuel so thats no problem

wtf guys? it ran great last night..

Slow start can be a number of things. Do u have anything that can be used to monitor different points? Are your batteries good? FICM holding around 48v KOEO, while cranking and KOER

Yup you need to monitor pids during the concern.

i thought it was batteries also...

but my degas bottle is covered in dry coolant from where its been puking. i filled it back to the min line. i checked oil and it was fine.

i then finally started it and went to the tail pipe, and a little puff of white smoke came out

White smoke is not always a sign of blown gaskets... There is numerous reasons for that. Puked coolant can be from over filling degas bottle, or needing the updated cap as well. Pressure test ur coolant system ... Or get something to monitor ur EOT and ECT temps.
