My SR20DE with 200k miles finally decided not to fire up, it cranks but does not fire. I figured it was spark since I smell fuel after a while, so I went ahead and started pulling the wires, and lo and behold found a ton of oil pooled in the left most hole. The car has a nasty valve cover gasket leak that can be seen all around the valve cover. I've been reading that oil in the holes can mean anything from a leaking gasket to cylinder ring failure. I pulled the plug and did not see oil on the end that protrudes into the cylinder so I'm assuming the cylinder is not full of oil. I cleaned the oil out of the spark plug hole and tried to fire it back up with no luck. Cleaned off the spark plug and wire of oil and added some dielectric grease but still not firing up. Does this sound like a leaking gasket causing this issue?
