Fuel injector or Fuel regulator for gas in oil of 89 civic 1.5l?

At first i thought the only problem was gas filling in the number one spark plug firing chamber with fuel coming out of the tail pipe. So i switched two of the spark plugs to see if it would change which chamber filled, but nothing changed. so i switched two fuel injectors to see and nothing changed. it still fills up in the number one spark plug firing chamber. upon doing research i found out that the fuel pressure regulator could also be a reason that fuel gets into the oil. if this were bad, would it affect all the firing chambers or just one? if the problem is the injectors, which one would i replace since i switched them and the problem was consistent with the first firing chamber?Fuel injector or Fuel regulator for gas in oil of 89 civic 1.5l?You need to check compression on all four cylinders. It sounds like you may a couple dead cylinders not firing

i would say the injectors. if you had a bad regulator it would do it in all of them. did you think it could be a leaking intake gasket. you also could have a bad plug wire not firing the plug. the plug is probably getting soaked with gas but no fire to burn it off.

Your plug is at fault,either that,the plug wire or the coil.
