Update and help please
 

So i have a post about my mustang having a misfire and shaking alot. so i have run it and it sounds good again. Yesterday when i went to check the oil, i opened the oil cap and smoke was coming out of it. Is that bad? please help.

Most likely some blow by from worn rings. But its not something I can say over the internet without seeing it. Is it a shit ton of smoke/steam or just a little. A little is normal.
