Gas leaking from exhaust manifold and a wet spark plug
I have a 1990 240sx with a SR20DET swap that has been running rich since I got it around a month and a half ago, but more recently I saw it giving off more white smoke out of the exhaust with no change in fluid levels. When I brought it home after it started smoking, I started it and saw gas spurting out of the exhaust in the cylinder closest to the firewall (4). I took out the injector rail and turned the key to see gas spraying everywhere from the 4th injector and replaced them all today. I did the same test without any leaking from the new (used) injectors but the gas is still spraying out of the exhaust manifold (right where the gasket is) and the spark plug is still dripping with gas when I take it out. I'm fairly certain a new gasket would fix the issue with the gas spraying everywhere, but I don't know what I should do to get the cylinder firing properly. The only other bit of information I can think to add that when I was doing the first oil change, the oil filter shot out and I drove for maybe a quarter of a mile in a neighborhood total with oil shooting out. I accidentally overfilled the oil a quart above and drove it like that for a day or so afterwards, then emptied it out to see the new oil pretty much black. Any ideas?
