broken bolt

[5.slow]

Just noticed that one of the heads that I got has a broken intake bolt stuck in it. Can a machine shop get one of those out pretty easy or am I in for a problem?

I just bought a set of gt40 p and when I took them off I broke one of the intake bolts off from where it had a water leakin on the bolt over the years so it was all corroded. But yea I would think a machine shop could do it no problem. Or u could do it yourself if u had a few different easyouts to try. That's what I'm goinb to do

Should be able to

I have some easy outs what type of drill bits work best? I never seem to have ones strong enough to drill a hole into bolts without breaking them

[Beav]

It's not how strong they are so much as your technique. It takes a steady pressure and it helps to lubricate... I'd consider paying a shop to do it since it is already off the car.. Corroded bolts can be harder to remove...

IF, there is any sticking up, you can weld a nut on them. The heat also will serve to help break them loose.
A good "chemical" based penetrant sprayed on them several times a day for a couple of days will allow it time to get down into the threads and loosen them up.
If you drill them out, look for a small set of reverse twist drill bits. You run the drill in reverse to drill out the broken bolt and sometimes they will loosen and the bit will catch and spin them out.


If all else fails, just beat the head with a BFH (Big ******* Hammer) until your anger is gone, then go get a different head.

That will work too.

I'll definitly consider the bfh and bfg if I get frustrated enough but someone told me I should try aerokroil on it. Anyone have success with this penetrating oil before?

[dreamstang]

Aerokroil is the best! That's all I use.

Still do as Trojan suggests.soak many times and let sit.
