okay heres a picture of my old plugs I just replaced today. the two middle ones have a lot of ash build up on them. my best idea is that I am leaking oil in due to old valve seals.... any other ideas?

 

looks like you may be running lean up top too.

I CAN'T SEE ****!

 

goddamn son. yeah the oil thing and a fuel problem is what i think

 

my plugs look burned like that to but wtf is with plug 2? that **** looks melted.

 

is this a stock motor?

 

yes this is a stock motor, never been rebuilt and has 235k miles on it...
the second plug is not melted thats just build up of that gray ash stuff...
if its running lean, how can I fix that?

You're probably fine...do you run your car hard? race? Do you have intake/header/exhaust? which ones?

If you have bolt ons maybe you'd want a fuel pressure regulator so you can bump the pressure a few psi.

If it's totally stock i wouldn't worry about it.

you ever use a fuel or oil additive? if you are, then that's the problem. either that or the valve guide seals.

These dpfi engines tend to run lean. These are the results after 230k miles of use. Just a fact. btw, no 2 looks bad man...
