Thread: Bright red exhaust manifold

I remember about 3 years ago, maybe a bit longer. I was driving home in the evening, it was getting dark a little bit. I noticed that my engine is pretty hot! So I pulled over and popped the hood to see my Front Exhaust Manifold bright red, I mean it was glowing like lava! Ahhh. So I turned off the car and let it cool off.

Drove home 5 minutes later and never seen that happen before or had any problems with that manifold ever again.

Just curious on what could have caused that, Kind of makes me laugh a little bit and makes me ponder.. Hmm

ive heard of it happening from a clogged cat. wierd that it didnt happen again though...

enough to cherry the manifolds though? i have yet to see that.

Lean wont make the manifolds glow, hella rich will tho raw fuel burning in the manifold.

super hella rich, ive seen it before on the wagon but it was because the carb was tuned super rich
