broken bolt in the block....

[ttocs]

in the process of replacing my gt intake with a cobra a bolt broke in the block that holds the lower in place. If it was one in the middle I would be less concerned but this is one of the ones that is on the end(front drivers side) and I am sure it will leak with out it....... What do I do?

Thats happened to me before but I was able to use an EZ Out ( a drill bit that you drill into the bolt that threads the bolt out)

I tried one of them and it didn't do anything. I tried drilling a small hole in the bolt to help it and it didn't do anything...

I'd try a larger ez out and if that doesn't work I'd say you need to continue to drill it out and use a tap and die to rethread. Good luck!!

remeber that its a right hand drill bit

There were 2 different types of back-out kits and I got the cheaper one since it looked like it would do less damage to the bolt. I will get the more expensive one tomorrow and try it. I don't know if I can tap it since from what I understand this bolt hole terminates in part of the coolent passage. This bolt needed RTV on it and probably just corroded from the time in the coolant(14 yrs). If I drill and tap that will leave the broken pieces in the coolant passage and I imagine that will cause problems.

I used something similar and it didn't do anything.

If I did need to drill and tap it could I flush the coolant passage to get rid of the scrap pieces? It is the #6 bolt in the lower intake manifold if that helps any......

Last time this happened to me, (depending on how big the bolt is), i just spot welded a smaller nut onto it and then turned the nut and the bolt turns out. Dont know if you have a welder or if the bolts even big enough.
