antifreeze on top of intake

coolant
I replaced my intake manifold gaskets a couple of months ago. I am now seeing coolant on top of manifold on both sides of thermostat housing. I torqued manifold bolts at 35lbs(in sequence). Is it possible that I need to retorque? I put rtv around passages on gasket. Is there a pressure test that I can perform to see leak?

It is possible you may need to retorque, but doubt it. If it is puddling around thermostat house I would check there. Did you torque the housing? If so you probably cracked it. Use a can of tbi cleaner and spray around the intake while the motor is running, if the motor bogs down then yes you have an intake leak. When the motor gets warm you should be able to see where it is coming from. You might also check you coolant sensor, I got a leak on mine once. Good luck.

Sounds like you need a little sealant on the threads of intake manifold mounting bolts.
Drain coolant first and do one bolt at a time.
Only do the ones that are leaking.
