Alright, i have the DC Sports Header on my tC. I could not get rid of the rasp so i took the header off to look at a couple things and i noticed that my O2 sensor was bright red. Then i looked in my header and noticed that it was also bright red, all the way through. Does anyone have any clue what would cause the gas coming out to lay down a red residue all over everything in it's way. Any insight is much appreciated, Thanks

 

I'm guessing it's caused by the same thing that turns spark plugs red.
I found a page here that makes the following statement;
Guess we'll see if anyone has any other potential explanation.

 

thats just the cars blood

naw on a serious note, like stated it maybe same thing that turns spark plugs red.

 

something that burns red....interesting...

not sure, but if the plugs have it also, there is definetly something in the gas then

but with the crappy gas now-adays, its not surprising

 

sh&tty thing is, that Gas is crappy, but their prices are still up.

 

I've been asking around and heard that BP gas leaves that red residue because of the additives it uses. And of course BP is what i use Imma switch to Sunoco for a while and see. The ethanol supposedly cleans out your system very well.

 

try running shell. it meets the top tier requirements for toyota.

 

I could try but there is only one around me and it's 40 miles from my house. It's only 2 miles from work, but i hope i never need gas when i'm at home

 

or if you have a Chevron/Texaco also.

 

some gases are dyed for example certain types of diesel are different colors i dunno tho gas is clear

 

ive had the red residue and asked a local shop and they said it was from running rich.

 

.. did you somehow suck a small woodland animal into your intake?

 

"cars blood" lol

 

Shell makes valves and stuff yellow cuz of their additives...

 

No offense but your local shop must not be too smart. Running rich causes a black residue, and running lean causes a white residue. A light brown, almost tan residue is right where you wanna be
