About a week ago my weld on the exhaust right after the cat broke. Its tied up by wire until I get it rewelded. So, ive been driving the car and all of a sudden today the car started sputtering even more then it already was since the exhaust is open. My exhaust header gasket has been blown on the left and right corners and my gasket from the turbo to manifold gasket also blew. Now, when the car started to sputter it started to smell like gas so i shut it off and tried seeing what happened. the weld on the header have hairline cracks in them and there was gas coming from them...????anyone know. I pulled the plugs and wires and the #1 & 2 had some gas/oil on them while 3&4 were just a little dirty. But smoke started to come out from the plug holes in the valve cover and the car was already off for 10 min. While this has been happeneing today the car hasnt ran long just long enough to try and see where it was coming from. PLEASE HELP! thanks
 
Its normal to have some moisture in the exhaust system. Are you sure its not just water that smells like gas a little?

If it is RAW fuel you need to check you Spark plugs/ ignition coil pack and wires first. Then move on to O2 sensor/ FPR.

Do you have an adjustable Fuel Pressure Regulator?
 
Its def raw fuel> i did a comp check and #2 is dead 1,3,4 have compress around 180. so now i gotta keep trouble shooting. i have a rrfpr. my plugs wire and dis cap all seem ok. the cap is a msd.
 
its gonna have to be either the head or the block. im guess i blew the ring. also possible the valve is stuck or not opening at all. thoughts?
