What Are You Doing To/With Your Car Today?

Well after help from everyone figuring out that my flex plate bolt was rubbing on the inspection cover and taking care of that, everyone pointed out that I had an exhaust leak. Well I knew that, but it was low on the priority list. So I decided to track it down today. Hooked up my leaf blower to one of the tailpipes, plugged the other, and sprayed down the exhaust from the engine back and discovered a pretty major manifold leak on the driver side near the firewall.

Now to decide how to handle it.

Pull the manifold, inspect the sealing surfaces, they usually leak at the center 2 ports, slightly warped manifold. Have it machined straight and true, new gaskets and good to go again.

On a second thought if you have the flat flange 340 style manifold it is easy for them to blow that gasket out at the manifold to the exhaust pipe.

Other style bell flange manifolds are easier to keep sealed, just got to keep them tight.
