Inlet Manifold Leak
Hi,
I'm now on my 4th set on inlet manifold gaskets on my 427. It isn't a serious leak, but I occasionally get steam from the right exhaust for a short period until the engine is thoroughly warmed up.
The joint is weeping into the #1 cylinder inlet port. I've tried various gasket manufacturers, but they all seem to creep eventually, resulting in the leak.
I don't use the front and rear cork gaskets, so they're not preventing it from seating fully. The heads are CNC ported Edelbrocks, as is the inlet manifold.
What is the consensus on the best gaskets to use. I'm probably going to change to a waterless coolant to avoid the pressure build up, which is probably causing the gasket creep.
Thank you,
Paul
