A friend of mine was passing another vehicle last night and said he was about 3/4 throttle when the truck started blowing white smoke. He got back home and noticed the truck had blown the oil cap off and oil was everywhere, has a bad vibration and EFI says misfire on #7. Is there any chance this could just be an Injector? Sounds like a more than that to me. Thanks

Sounds like hole in piston or cracked piston.
