Another Question about coolant leaks

[Salmon Stalker]

I posted this on the compact forum, but haven't recieved any respones yet, so I thought I would post it here too. After replacing the intake gasket on my 1996 blazer with 4.3 vortec v-6 it is still leaking.

 

I'm thinking the only other posibilities are head gasket or freeze plug at the back of the engine. I'm looking for opinions and a bit of info on how I should go about finding out which it is. Would a pressure test be in order? If so should I have that done at a regular shop or should I go with someplace like Walts radiator?

 

Once again, any help would be appreciated.

Yea, you're definitely gonna have to pressure test it...possible external head gasket leak or freeze plug? You might have to pump it up and look at the back of the engine with a light and a mirror. Man, that's a bummer.
