The nuts where the throttle body goes on the plenum broke. So now i cant tighten the throttle body so the car leaks coolant. What would you suggest? It like the three bolts that stick out of the plenum were glued in but now they broke. All I have in mind is to tap the hole and use a bolt instead of the nuts. If anyone else has had this problem please let me know how you fixed it. Thanks

Take one of the studs and go to the auto parts store. Match up studs that are the same thread and get red loctite as well. Put the loctite on a small portion of the threads and screw those ends into the supercharger. Then put the tb on and tighten the nuts
 
how can i screw the ends into the supercharger? the studs weren't bolted in before they were like glued on there
 
they look to be studs, in this pic it has no studs installed it seems, see the small holes.

some heat from a plumber soldering torch should help break the one that still has some sticking out, the other one you can try to drill a pilot hole and use a easy out but that never works out well, due to not having a flat area to drill into, thats into the stud.

bet bet may be to drill out the broke one, that snapped inside, and use a large bolt and nut.

i'd get a brand new drill bit for metal, maybe 2 of them and do your best to stay straight on the stud, and not stray into the metal around it. and some wd-40 to keep spraying on the bit and hole you are drilling. and stuff a rag in the inlet opening, you dont want anything to get in there.
 


i see what you mean. I got the broke one out. now the one that snapped inside is a different story

They are studs. The nuts come off them. They are also M6 x 1.00 IIRC.

Being so small..they don't require 50ft lbs of torque.
