Puking coolant what to do?

[bouboy02]

Over the past few months when my truck is at WOT it'll puke a little bit of coolant it doesn't burn any, I'm thinkin its possibly a cracked head but I don't know, is it worth pullin the heads and figuring it out or should I just run it and see if it gets worse. Thanks mike

How can you have been around since July of '09 and not know the answer to this? It is one of the most talked about subjects on the board.

Either your coolant level is too high in the degass bottle, Your bottle cap needs to be replaced (it should hold 16 psi) or your oil cooler has clogged resulting in down stream issues.

Read the first link in my signature if you haven't already. It explains it all.

Consider one of these to check for exhaust gasses in your coolant.

Get a monitoring solution like an Edge Insight so you KNOW what is going on with your engine. It is not optional with a 6.0.

Ok maybe I worded it wrong I know its a head issue, I was just wondering if u guys think just blown hgs o if it might be cracked heads, and if its safe to keep running it or if I should tear it down no need to be a smart azz lol
