Actually RT87, there is very little torque on the intake bolts on these cars. That is where the original problem stems from. Failure to use threadlock on the bolts during re-assembly will cause them to loosen over time and start leaking again. The intake bolt torque on a 3100 is only around 18 ft/lbs on the outer short 4, and 128 in/lbs on the 4 inner long ones using the new design metal/rubber gaskets.
