I bent a pushrod by over reving awhile back and replaced it. After that my car's been misfiring. My o2 sensor and cynder 3 misfire (same cylinder bent pushrod) codes popped up. I changed my o2 sensors out and same code still came up. I checked my cylinder 3 spark plug and it had oil on it. I also checked my compression, and it was a little lower than the other cylinders.
Any advise will help

Oil on the spark plug? That sounds serious. Where is that coming from, the valve guides or rings. Not a good sign.
