Just installed my cam/heads and when I went to drive the car it started over heating. Bled the air out of the cooling system and was filling the radiator while the car was running (so I could keep filling it as the water was being pulled through) and out of no where I see smoke and hear water hitting my passenger header. Sure enough I look under the car and there is water pouring onto the end of the header. No water is being spilled from the engine inside the engine bay as far as I can see so I'm really confused. Any Ideas?

 

My best guess is that you have a blown head gasket and water is squeezing out at the back of the head. The fact that it happened after a cam install is coincidence.

 

It's not a coincidence that it happened after he also did the heads though.

What gaskets did you use?

 

+1 and he said that he changed heads too.

 

I got NEW GM factory steel gaskets and it's more than seeping it kinda just poured out. I was thinking that maybe the coolant stop or whatever they're called on the back of the head maybe loose or something. I ran it twice and drove it once before this ever happened

 

Did you put the plug in the rt cylinder head near the firewall?

 

or the coolant crossover plugs on the heads too?

 

Yep, forgot about those, maybe you left them or one loose.

 

Yah, it's gotta be one or the other or even both. Get her fixed. Saturdays' Super Summit is quickly approaching. Don't wanna miss out.

 

That's what it was just put it in haha. Thanks for the help everyone! Yet another problem solved thanks to the internet.

Sweet, glad it was easy. Remember always start with the basics, don't overlook the obvious.
