lol, (hella fast!!) is just to get u guys to read my problems, sorry! but anyways i was working on a buddys car last night and realize that my old compression tester was at his house, so i took out my spark plugs and was going to perform a test, but i came to find out that my #3 plug was white and #'s 1,2, and 4 are brownish gray... what could be the cause of #3 plug to be white and diffrent from the others? is this something to worry about? The motor runs strong and no signs of smoke or anything... BTW, I did do a compression test on it, and it came up 215psi accross board...IMO i think that my motor is still pretty healthy...But why is one spark plug color different from the other three?

i guess the real engine builder's is not intrested in b16's??

 

What has been done to your motor? Stock?

nm i just saw the title. nothing's wrong they prolly just been in for a while.

 

Put in a new set of plugs and read those after a while. Could be running lean, hard to tell with just a brief description over the internet if you know what I mean. Swap plugs, read after a few miles. Go from there.

 

so whats good, white or brownish/gray plugs??

 

brownish gray is normal.
