Just checked now and oil smells like gasoline, badly... bad sign obviously, this further tends me to think that it's the injector that's bad, spraying too much or not enough gasoline into the combustion chamber which is then not properly ignited thus what's left leaking down in the oil pan, and of course in the meanwhile creating a misfire too, hope it's this thesis the one that's valid, if the cylinder really has no proper compression then it's gonna cost a buck more that's for sure
