Intake Manifold not Sealing?
Hello Everyone – I recently replaced the intake manifold gaskets on my 1972 LT-1. Everything was fine for the first few hundred miles but now I notice some coolant pooling around the second bolt in from the passenger side front (next to the heater hose connection. The bolts are torqued to the proper spec. Any ideas what I might be causing this and/or how to fix (maybe replace the intake gaskets again but I am not sure what I may have done wrong the last time)? Any thoughts are appreciated - Thanks

I also like to put a bead of sealer around the water jackets on both the heads and intake as well before installing the gaskets and torquing everything down. Also what did you torque your manifold bolts to and did you follow the correct torquing sequence?

Thanks for the suggestions. I will check the heater hose. I did use a small amount of silicone around the water jackets and used the specified torque value and sequence contained in the repair manual I have.

Don't forget to put sealant on the threads of that bolt! It is not just torque.
