COOLANT LEAK... AROUND FUEL INJECTORS??

2000 Pontiac Bonneville

I have a 2000 supercharged Bonneville with about 90K miles. I have noticed a coolant leak over the course of the past few months that has been getting worse.

I looked under the hood and noticed coolant collecting in the recessed areas around all the fuel injectors.

What needs to be replaced?

If the intake manifold gasket is the problem, what other replacements would most likely take place at this time.

Being that quite a few parts will be removed, it's probably advantageous to replace some other parts. Maybe the supercharger gasket?

Anything else?

I just had that problem. Replaced upper and lower gaskets, valve cover gaskets, thermostat gasket, etc. Messy job, especially since I have a Grand Am and the engine is poorly designed! It took 2 days. Now my rocker arms are making noises. WHAT NEXT!
