Gas smell coming from my tail pipes - 2005 Lincoln LS

Getting water in the tail pipe is a good sign as the engine will always have moisture when not running. Water on spark plugs is a bad sign as there may be a leak from a cracked cylinder head which is then a major job, the car should be running erratically or will stop.



To check if this is the case take out the oil dipstick and see if the oil is light brown instead of black then you have a problem as mentioned so needs major overall to the engine.

Gas or exhaust make sure catalytic converter isn't clogged you will loose a lot of power .good luck

May have to remove the fuel injectors & mail away
to be ultra sonic cleaned & flow tested

I suspect you need a new exhaust converter & oxygen
sensors--- once the fuel issue is solved

Why is a repair shop not your go to place for answers?

Smoke from tail pipe or smoke from under hood?
A general rule of thumb if it is coming from tail pipe the color of smoke will tell you a lot.

White and thick means head gasket failure, Blue means oil is being burned.

I would recommend you check the seal of everything and make sure it is cleaned that had to do with vacuum or fuel distribution. EGR valve (gasket fails sometimes) IAC valve, MAP and MAF sensors, Fuel injectors, FPR (this will need replaced if leaking),

Also check you coolant and oil look for signs of either one mixing with one another, smell you coolant and make sure it don't smell like gas either, look around where the head meets the block and make sure you don't have any coolant leaking there. The smoke if from the tail pipe makes me think head gasket and these are simple checks. They are not 100% diagnosis but can lead you to the problem.

Also one obvious thing would be make sure no one put anything in your gas tank.

I would most likely look at the injectors first then the head gasket next.

your tail pipe is always going to smell like gas the white smoke is oil being burned from worn out valve guides or rings.

If the smoke comming from the tail pipe is black your running rich. If thats the case the entire fuel system has to be ckecked out. Injectors could be leaking, a bad pressure regulator,stuck return line ,a coolant temp sensor could be telling the ECU that the engines cold give her more gas. I don't recommend doing fuel service unless your qualified to do so for the obvious reasons.
If the smoke coming out of the tail is grayish you have a bad head gasket. If the smoke coming out of the tail is blue you have engine oil getting into the combustion chamber. keep me posted

sounds like it running to rich of a fuel mixture, the first thing i would do is replace the oxygen sensor and also make sure its not misfiring an any cylinder, start there, hope this helps.

Chances are it is water coming out this is normal to notice some water dripping out of exhaust periodically as the car runs, If the liquid actually smells like gas i am at a lose I have never heard of this occuring.

yes it could be but you should be getting oil in to the chamber also check your tail pipe if you have white smoke coming out that is oil if it is black that is to much fuel if you are getting alot of water then you definetlty have a bad head gasket you will get some water that is condensation built up in side the muffler but that should burn off quick have somebody hit the gas pedal while you watch the tail pipe if it starts blowing water then it is without doubt good luck hope for the best but prepare for the worst let me know if you need more help

Check the fuel pressure regulator. It should have a vacuum line attached to it - disconnect the vacuum line and turn the ignition on - if fuel come out then that's your problem. DON"T do this while the engine is hot or you could start a fire!
