Coolant leak...

[TheRainman]

Alright so the other day I noticed my 96 gt was running a little sluggish, I just figured it was another vacuum leak because I heard a hissing sound and it was doing the same thing as the last time I found a vacuum leak. well I popped the hood and looked to see if I could find the problem, turns out I have a coolant leak coming for the top of the manifold where the first injector on the passenger side is. I didn't have anytime to fix it this past weekend because it's Spring Break so I just parked it at a friends house and rode down with them. Yesterday when I came back the leak was worse since it had been sitting. It idles fine, but when the RPMs get up above 1700-2000 it starts cutting out. I don't know if it is because the injector or seal on the injector is bad. Has anyone else had this issue?

Yea ur manifold sounds to have cracked dude . You should do the frpp pi intake swap or get one off a car at the wrecker.

That's what I was afraid of... Now to decide whether or not to go all PI top end, heads and intake.

It would be not a bad time to do it man. The bump in hp and compression is nice

 

[TheRainman]

Might as well while I've got it all pulled apart, and do a mild cam in it. I had planned to stay nPI but now that it needs work might as well. How could I tell if its been cracked other than taking it apart?

You'll see water pissing out

It seems like it only leaks when its off though. I haven't had much time to look so I'm gonna have to take a real good look tomorrow. Right now it looks like I'm stuck driving the tank, aka the suburban of my moms.

When my crossover first cracked the only way I knew was a slight steam hiss when I shut it off, running it was fine

As time went on it got much worse though

So I had some time today to look closer, looks like I have a tiny crack in the manifold crossover

Welcome to the "when" not "if" your crossover will crack club

Such a good reason to upgrade to a PI manifold though

Pretty much what mine did..it was cracked at the crossover..its a common problem..just do a pi swap. You wont regret it..even just the intake

330 for the win! time to go pi, be sure to take that spark plug out and let everything dry up, use compressed air if you have any
