what do you think it means when the diver side front header turns brown (about 4 inches ) heat ? thanks for any reply.

 

Possibly, that the engine has been running?

 

Hey now - we shouldn't jump to any conclusions. What evidence do you have of this?

GD

 

I'll figure it out.

 

corrosion?

 

A picture might help...

 

You say "Brown" , but you talk about heat and have opened the thread in the "Cooling" sub forum ...

If I had to play "Thread Forensics", I'd be left to conclude that maybe your saying "Brown" but really mean "Dull Orange" ?

Clarification may go a long way toward people being able to offer targeted , accurate responses .....

 

saw many questions in the cooling forum about over heating and not seeing a heating forum...well.. that's were I went. the block doesn't seem to get hot enough to open the higher temp stat so maybe the heat right there is causing the 'burnt orangish color on the front header. dropped a 160 in there with a small hole in it . see what happens the plug looks good. hard to chase this down when I only chance to drive once a week. thanks for your help.
