well ithought i had a stuck injector when my crank case was full of gas so i figured out that it was my number 2 cylinder having the problem by the amount of gas in it. so i cleared it out put new plugs wires, and distributer cap on it and and a new injector still no luck. my car is still smoking like crazy and now leaking gas from the motor some how has anyone had this problem or have a clue what could be wrong? it is a 91 16 valve motor

Dude, from what I know about engines, it sounds like yer rings are shot! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt='
![]() Just where is the gas leaking from? When ya say that yer crankcase is full of gas, do ya mean the bottom end (where the crank and rods are) or the top end (like inside the piston chamber)?

Like HotRod said, it sounds like rings. Looks like time to rebuild the motor <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

Hot rod guy is on the right track. You should do a compression check to figure out if its a head gasket or blown ring. Take the readings from each cylinder, you have have +- 15psi within each bore. Find the reading that is the lowest, pour a little motor oil in the spark plug gallery and test again. If compression goes up, then its a problem with the rings, the oil acts as a sealant to raise the psi. If nothing happens, your head gasket is most likely shot.
