Nah. It's not firing at all. If that's the caes the #2 header would be the same temperature as #1 and that's not the case. Not to mention it's blowing out (burning) water like a mother.

 

You might have a cracked head and thats why 1 & 3 are so clean. Yes your head gasket may look good but the head might be cracked which sometimes can't be seen by the eye. I forgot to mention have the shop either magnuflux the head or sonic test it if I remember right. beens years since I've done that.

 

All that is now getting done. Thanks.
