I removed my old header and put on a Greddy SS header yesterday and noticed that all of my exhaust valves were a light grey/white color. Does that mean that the engine is running on the lean side? I'm running a Vafc on a 94 lude vtec.

TIA

 

Anyone? I know if they were totally black, I would be running "rich". I just don't know how the "normal" exhaust valves look.

 

yea I think that its running real hot. try to richen it up a bit

 

most cars i see look like that so i wouldnt do anything to them ... check your plugs and go from there

 

Thanks for the info. Is there a website that dipicts sparkplugs and the damage that has occured to them? (Along with the reasons for the damage?)

 

I am pretty sure the good ol' helms manual would tell you that.

That is normal for the exhaust valves - nothing is wrong with them.
