Exhaust Manifold - Pre Monolith Glowing
I have been in the process this summer of restoring my 1985 GSL 12A. I have changed fuel, fuel filter, spark plugs, distributor cap & rotor, oil, antifreeze, and general cleaning of the engine compartment. So I got it started and it is running pretty good, maybe a little high on the idle but over all good. So as I get it up to temperature smoke starts coming up through the engine compartment and a look down to see that the pipe between the exhaust manifold and the 1st pre-monolith converter is glowing red hot. So I am looking for some advice, is this a pre ignition issue, timing issue or is something partial plugged in the exhaust system. I do have some back pressure coming out of the exhaust and it is running smoke free. thanks in advance.
