i bought a 325ise e30 not knowing if it runs or not so we tried it and it ran but the exhaust was glowing red at high rpm so we stripped the head down replaced all the gaskets filters plugs and pumps banged it all back togwether and its running sweet but the exhaust is still glowing red anyone got any suggestions
If you have a pyrometer hit the exhaust before and after the cat.. if the exhaust is hotter AFTER the cat the cat is fine, if its cold then the cat is plugged..
the reverse is true for the muffler section

Hey starmavin...what will the black smoke tell you? Just curious..retarded timing can cause these issues too, but that is reaching. I like the cat idea, an infrared thermometer will tell a story.
Your plugged - probably the Cat. Sometimes that honeycomb breaks up and can cause restrictions. Unbolt the muffler and the cat and bang the hell' outta them on the concrete floor - see what goodies you might have in there? Dead mouse, cat, jimma hoffa?
Good luck.:lol:

Your manifold is glowing? Do you have full power? Sounds as if your cam timing is off a tooth or so and is letting combustion exit too early. Was the head shaved more than .020?
If your head has been shaved a lot, your cam timing is off. I'm not sure if they sell a block shim for the m20 but that is most likely your problem. When you have the head cut too far, the cam timing will be off a few degrees. This will cause your problem.
I am just thinking out loud here. If the head was shaved alot theoretically you would retard the cam timing slightly...??? The tensioner would then compensate for the extra slack. It seems like you might move the torque curve around a bit, but is this really causing any problems? Could there be a water flow problem through the head? Are the head gaskets identical for the 320 and 325?
Can you move the ignition timing around a bit on this particular car, to see how it affects the "glow"?
One last thought...it could be a girl car and we simply do not understand it!
