So I got everything back together and started her up for the first time since Nov. Intake manifold gaskets and trans rebuild seem good so far just running on the hard. It would have been a total home run except my thermostat housing is leaking... again.
Starting about three seasons ago, I've always had a little puddle of coolant on the intake manifold. I changed the thermostat, new gaskets and still leaked. Pulled it apart, new gaskets and same thing. I think I tried 2-3 times but just lived with it. This time I ran a thin bead of RTV around the gasket avoiding the metal rivets (the leak is the lower part of the housing to intake section, not the upper half). I always clean the surfaces nice and smooth.
Sure enough it immediately had drips coming out. I tried torquing a little more but no change. I'm sure I can fix this if I run a thicker bead around the perimeter but would have to ignore the rivets. Since the sender is mounted higher, does it matter if the rivets are covered in RTV on the lower gasket?
Do they make a thicker gasket that will compress more? I do notice a gap between the housing and manifold but they feel like they mate up dry.
