equipmentS14Sr20det, rebuiltCP Pistons

Upon removing my upper intake, i found a small puddle of coolant in intake runner #3. I had been noticing considerable white smoke after boosting around 18psi a few times. I figured thats what I get for not replacing my cometic head gasket when I rebuilt the engine. I also added a Circuit Sports Intake Manifold gasket Any chance the HeadGasket is not the issue, but the actual CS Gasket?I am going to replace the HG, with a new Tomei one.I realize that it could be both the HG and the CS Gasket, but I cannot think of how Coolant would get in to the runner via the CS Gasket. I am still lenaing towards bad HG. Any ideas?

I'd replace the head gasket no matter what, i wouldnt reuse it. That CS gasket should not be the cause however if there was a line scratched from the coolant passage to the third cylinder than maybe but i highly doubt it.

Change the head gasket. Tomei ftw.

I think i found the problem.I dont hink its supposed to look that way

Cylinder 3 just died.

Moral of the story...if you see white smoke...and it smells sweet...its probably antifreeze....you probably have a busted head gasket
