Pressure plate is history. Flywheel will have hot spots on it, and you'll eventually end up losing the clutch, most likely the disk springs. You'll be better off finding a new flywheel and redoing it the right way.
Don't half ass anything. Especially when it comes to vavle/drivetrain. You will regret it. Have you ever extracted a broken bolt before? It is very simple. If you want I have about 5 stock flywheels and you are more than welcome to come and get one.
how long ago did you do it? i say if it was recently tear it back apart and use an ease-out bit and put a new bolt in. I broke one of those off on my civic and lets just say problems do occur. FIX IT! lol
not a good idea to run it like that. you should be able to get that bolt out with a little effort. if not, i also have a couple stock flywheels laying around. one of which is already resurfaced and hasn't been used since.
good news, i got the broken off bolt out in a matter of minutes. I got a tool from a guy at work that is like a reverse screw, i drilled into the bolt a little then used the tool, it walked right out like nothin.
I am replacing all the bolts, and i wont be using an impact gun to just run them in this time
its a fidanza flywheel btw.... so good thing i got it out.
