over the past week i pulled the supercharger off my car and yesterday i reinstalled stock intake manifold in place of the blower. anyways while i was tightning the bolts down one of them broke in the head. (im still using the bolts used to mount the supercharger so 4 of the spots are bolts instead of the studs). the one that broke is the top corner on the driver side of the motor. anyways the car started and ran just fine and i couldn't hear any air leaking out around where the bolt broke. i know i need to get the broken part out of the head but would i be ok to drive the car temperarly tel i have time to pull it all apart again. have any of you ever broke one of the intake manifold bolts. and if so whats the best way of going about pulling the broken peice out.

 

yeah itll be fine. if anything you might develop a small air leak and it might screw with your idle. get it fixed, but its not like impending doom if you dont.

depending how the bolt/stud broke, you may need a screw extractor. or possibly weld another screw or something onto the bolt/stud and try to turn it out that way.

 

for one, you shoul use studs and they sell 12.9 grade studs so is harder to snap. 2, using bolts migt damage thread coils an that would be a pain to repair. you can't just rethread it 3, if its sticking out a bit, you can use locking pliers to let it go loose, otherwise drill it out wit screw exctractor kit.. really, if you have enough access to drill it out, that might be the easiest thing to do without removing anything.

 

Try left hand drill bits available cheaply at Harbor Freight (the one's they were carrying were actually good quality, but that was a couple of years ago). They also have the matching screw extractors from the same company. Otherwise tool store. If it's not in really tight, just the act of drilling it for the screw extractor will unscrew it.

If the bolt broke because it was slightly too long, and it bottomed in the hole in the block, then you may have to remove the mani. This will expose the bolt, and it will be easy to get on it with vise grips.

Wear safety glasses with screw extractors - sometimes they break and send out shrapnel.
