my 93 accord's engine has 2 missing exhaust manifold bolts, the far left, and the one right in the middle, they are not exactly missing as opposed to being cut off and stuck in, I tried drilling a hole and then using easy outs or whatever, but they are way too stuck, my question is will there be trouble if I just keep those like they are, and just tighten the good ones?

I once broke a bolt on my friend's valve cover. We left it alone and it still runs with no leaks.

If you do not have any problems l suggest you leaving it as is and see what is going to happen.

Good luck,

Sam

It is less a problem then broken bolts on the intake manifold. Threre is a problem with an exhaust leak and possibly drawing in air which could throw the 02 lsensor off.
