I'm running an Evo 3 throttle body on my 4g93t and it appears I have a water leak. I've just run my hand underneath the throttle body and there is coolant across the bottom of it but it doesn't appear to be coming from the hoses. It's like its leaking at the gasket?

When we put the throttle body on we noticed it looked like there were screws missing on the inside but didn't worry about them as it didn't look like they were holding anything. I'm concerned this may be the issue as the previous owner clearly wasn't running water through the throttle body as one of the water fittings was snapped off.

Anyone had any experience with this?
 
It would be the seal in your isc/fiav

remove to, under it u will see the isc with 5 screws, remove and throw a new seal on it
 
I went to the trouble of having the Haltech tuned to run a cold start which now works perfectly so it'd be a waste to get rid of it now.
