Well let me start off with I have a Sunfire 2.2 ohv ..well I got it garaged now and I took the Valve cover off to see what I could Diagnose..well..first off I have a quick question....and I supposed to have Gas everywhere in the Valve area??..I really havnt gotten any further than that I wanted to ask before I got into it more deeply..I dont think its supposed to be like that but I could be wrong..it Idles rough and it uses up waay too much fuel and it leaks in with my oil so I have to change oil atleast twice a month, I should mention the Charcoal Canister was damaged and removed but I dont that is the biggest part of the problem....oh and when I start the car it smells strongly of gas and it backfires occasionly...just thought maybe someone could help me out thanks
"yes officer I DO know how fast I was going.."
Gas is the valve cover, nope not at all.
Gas should stay in the cylinder walls, also called the combustion chamber.
I honesty have no idea how gas could get up there, since the only way gas goes into the engine is through the injector, but still that is just tiny amount, and it sprays in there and mixes with the air and spark plugs ignites it, so really have no clue whats up with your car.

I"m thinkin it was put back together wrong when it was in the shop or some sort of gasket is missing or something to do with the valves...O.o
"yes officer I DO know how fast I was going.."
could leak into the oil via cyl. either that or someone is playing a mean joke on you.
beer is like a chick.. well not really its just beer, it be cool thou huh?
the seals could be missing in the cylinder head, there should be seals on all the valves, however like Rob said, i still don't know how gas could have possibly gotten up that far, how much was there?

What the heck is a "Datsun" ?
What year is it? Does the canister have holes in it?
Leaking injector s?
Gas in oil = burnt rings. Correct me If I'm wrong here, but on the compression stroke, if you've got bad rings you will get what's called blow-by. Air and gas will be forced out of the combustion chamber into the eagerly waiting oil pan. But if you had a bad compression ring, It would be running REALLY badly. I don't know that that cylinder would fire at all as a matter of fact. Which might actually explain your rough idle situation. Thing with burnt rings, though is that it goes both ways. Air and gas blow out, oil blows in. So take the rest of the head off, and tell us if you see oil in one of the combustion chambers.
Gas in head = 7th sign of the apocalypse. lol This I've actually never heard of on a fuel injected engine. My best guess would be that since you know you're getting gas in the oil, perhaps it is being transferred with the oil up into the head. *shrug*.

there was enought gas to coat the bottom of the valve area..and the canister had a huge whole in it due to it being dragged after a collision so it was removed awaiting a repacement and its a 96 Sunfire (i love it btw and would hate to lose it..)....its been in the shop to have a head gasket replaced and a head bolt fixed..and I"m thinking something wasnt put back right....

I will correct you since you are wrong.
Blow -by, is oil is going into the combustion chamber due to bad piston rings. That is why when buying a used car you always open up the air filter box to see if there is oil, if so either the piston rings air shot or the PCV system isnt correctly working.
The littel bit of fuel the injector sprays into the combustion chamber is like microscopic, think of it this way with the piston going up on compression stroke, right before the fuel and air get ignited by the spark plug on a properly running engine there is 14.7 times more air than gas in there.
If you had bad compression rings your car would run like @!#$, misfire, rough idle, no power.

Thanks for the correction.
