Is there anyway to tell if my LS6 intake manifold is properly sealed since I've left the factory crossover pipes??

It fit down perfectly but I want to make sure its not going to leak. And if it does leak how can I tell?

You mean you installed the LS6 intake with your LS1 coolant pipes ("X" shaped)? If so, you might have damaged the bottom of your new intake if you've tightened down the intake manifold bolts. That is, unless you dremeled the bottom of the intake to clear the stock coolant pipes.

The car will run like **** if it's not sealed. Either get a new pipe and plugs, cut/weld your old pipe, or clearance the bottom of the manifold.
