I broke a bolt on the valve cover on a single cam. can i drive it like that?

 

i have 2 missing

 

I've been missing 1 for about 3 years now.

 

3 broken here

 

If it's the one[s] I'm thinking about, they are actually studs. You have to take the valve cover off and replace them from inside. They have a cap nut on top of them. Ppl get ham-fisted and break the stud off inside the nut. So, you'll need a new nut and stud for each one you broke. If that's not what you're talking about, let me know and we'll go from there...

 

i broke one of those

 

It'll cost you next to nothing to replace, if you do the work yourself. I wouldn't drive it around like that, but that's me...
