Default losing water!

I did a PI intake swap a few days ago and since then I have had water leaking out of behind the engine somewhere, but I cant see it. I thought it was the metal tube and its connection to the water pump nipple that I had to install in the valley, below the intake. But today I pulled the alternator and water pump off and it seemed to be ok. It is losing quite a bit of water and seems to be coming from the passenger side, rear of the engine.
Is there a freeze plug (or multiple plugs) in that area? Please tell me I didn't blow a head gasket!!

When you changed the heads, did you get new nuts for the studs? The nuts are meant as a 1 time deal and could be backing themselves off the studs. Try checking how many pounds you have with a torque wrench.

I didn't do the full PI swap. Just the intake. The gaskets and the intake itself doesn't look like it is leaking. Coming from somewhere towards the back of the engine. And I can't see anything wet from the top, just water running out from under the car.

I assume you mean the intake gasket, but as far as I can tell it is. It doesn't look wet at all around the intake.
Wouldn't there be some more symptoms if it was the head gasket?? The car runs perfect other than water rapidly coming out of it lol

Sorry just glanced and saw PI. You said though it started after you did the intake swap though. I'd say more than likely thats where the problem lies. If not the only other thing that I could think of would be freeze plug.

Maybe you should get a compression test done to make sure you dont have a blown head gasket
