Thank you for the responses! I will place a piece of cardboard underneath the car tonight when I get home and post the results.

Given the age of the car, would you recommend (as a precaution) replacing the radiator even it turns out not to be the problem?

With regards to the LIM, are these the gaskets? The reason I ask is that when I called O'reilly's they stated that they don't have a LIM, but did show 615-179g (gaskets) or 615-179 (Intake manifold kit - including all gaskets and seals).
