I was tightening the valve cover studs and thought I could get a little more and the drivers side front bottom stud snapped. Can I drive like this? Major problem? Fix asap?
VC stud? Usually find bolts holding down VC. IMO, if I had to run w/o a bolt, I'd prefer to have the middle one on the bottom.
Can you drive like this? I don't recommend it. VCs are a typical source of leaks. If oil drips on hot exhausts, there will be smoke at best, fire at worst.
Can I drive like this? Fire in a car is a major problem. You decide.
I don't quite get "valve cover studs" unless you have something other than OEM hardware. I don't know why some much tightening there either.
I would bet that once the valve cover is out of the way the remnants of a bolt could be backed out with a dental pick. May be a little solvent spray needed.
