my car is barly running its so rich. I can see the fuel comming frome the exhaust gasket. i was out driving around and it just started to act up everything for the fuel is stock. not sure what the problem could be? if need more info ask. thanks for the help
 
:hmm:....

What exhaust gasket are you talking about? head to manifold, manifold to turbo, turbo to o2 housing, o2 housing to downpipe :idontknow:...

Either way if you see fuel coming out of anything like that, you have a serious problem (which i can't understand how it could happen)
 
My guess is that there's a crack somewhere in the head...

Fuel goes through the intake side of head>into combustion chamber>comes out as heat through the valves>through the exhaust ports...

So im guessing either
A. Whichever cylinder its coming from isn't igniting and somehow the gas is going through (although i dont see how)
B.
There's a crack in the head through one of the ports allowing the fuel to go straight through the exhaust ports

Your 100% its fuel?? and maybe not coolant?
