Lbz head gaskets

[dirtboy726]

Running my race tune through town i rounded a turn and noticed alot of white smoke coming from my tailpipe.
I live 2 minutes away so i get it home and pop the hood. Antifreeze everywhere on top of the motor.
I figure it is the head gasket. But i was worndering if there is anything else i should check before going that deep. Stock motor ,no studs,built trans,duramax tuner tuning.
I was hoping it would hold until i got my spare motor home and ready. But oh well. thanks for all input guys.

could be the small hose that goes to the egr cooler, mine did the same thing the day I put my efi on it, small hose was dry rotted

yeah i would check hoses first head gaskets usually leak slower then explained.

didn't catch the "coming from the tail pipe" part

Turns out it was that small hose to the egr cooler.
I had the cooler blocked but it is now completely removed.
I am not sure how or why i had white smoke out the tailpipe from blowing that hose but i am glad my heads are staying on for now.
Thanks guys .

Turns out my y bridge is nfg. Allseason full delete kit will be on the way shortly. Leaving for work again on wednesday. So it will be going on early april some time.
That will hopefully cure the whistle i developed last week.
Which might explain how coolant got in the motor to burn off.
Always something.
