What is the best gasket sealant for the water pump and water neck/ thermostat housing? I have used a couple different kinds (including Permatex Super 300) and I always have seep leaks within days. It's driving me crazy. Both surfaces are clean when I apply, I tighten the bolts to the correct tension, I think I'm doing everything right, so it has to be the sealant...
Thanks guys,
Adam
