hey quick question.... does/is your manifold suppose to be glowing?!?! i was driving for like 15 mins and i stop by my friends house and i pop up my hood and saw that my exhause manifold was glowing... is that suppose to be normal??? my car is an n/a.... so if you guys know anything.. thanks

 

they can glow after some hard driving...usually noticble at night....but i dont think mine ever glew when i drove my NA. but there is an awful lot of heat coming out of there into those pipes.

 

My understanding it might be a lean mixture, correct if I'm wrong. My turbo and manifold was glowing red one day...look pretty cool, wish I had a camera at the time.

 

Yeah, you might be running too lean... No Bueno! Make sure all your fuel goodies are working right.

check your timing as well, if its off its just as bad as a lean condition

 

yeah... getting a cast iron manifold to glow takes some work! A lot of those vids showing a glowing manifold, are stainless steel turbo manifolds.... they are glowing from sheer heat & backpressure.

Deffinately check your a/f ratio, and make sure your exhaust is flowing correctly. Did the engine heat up when you were driving?

 

I saw the exhaust manifold on my old SAAB 900 Turbo SPG glow once... ONCE!

That was the end of that car...

possable cloged or partiually cloged catalistic converter would cause that manafold to turn red also.. i saw it on one of my friends old ford cars..

 

everything was good but that... car temp was good. timing is good... could it be maybe a clog cat? buliding to much back pressure?

 

I crossed some plug wires on a friends '78 Camaro once and almost the entire right side exahust was glowing like the sun, it would pop a little bit under acceleraton but we did not really notice a big performance loss....just a thought to check those wires.

 

dose it fill like your car is choeking, or lack powere and can't make it over a certain speed?
