Advice needed: Intake Head Stud

[KMoore68]

Hi,

I have removed my CIS in preparation for installing some ITBs.

I purchased a stud extractor tool and was removing the old intake studs in preparation for adding some longer studs to accomodate the spacers for the ITBs.

Unfortunately 1 of my intake studs broke off and a second one is quite stubborn and I'm afraid it will also break.

I was hoping for some advice on how I can remove the broken stud.

1. I purchased an induction tool that I used to remove the exhaust nuts when I installed my SSIs, is it ok if I try to heat up the broken intake stud with my induction tool? I have to be aware of melting the shroud so maybe that has to come off but what do you think?
2. The other option is to drill it and and use a reverse bit to pull out the stud.

Let me know what you think.

Thanks

If you have , or know someone with a welder, you could weld a nut to the remaining stud and then use a wrench to extract the stud. the heat from the welding process helps to break the bond between the steel stud and aluminum head.

Keep using heat and be patient, use a wet towel to keep surrounding area from too much heat.
If your going to drill it out make sure you use something to grind the top of the bolt flat, carefully mark center, use a center punch and start with a small drill bit first. You want to make sure the hole is centered otherwise you’ll be buying a time sert set.

You can get this on Amazon


soak the stud with penetrating oil overnight then pound on a slightly smaller size bit. don't need an impact wrench works with a normal breaker bar.

Got a pic of the broken stud so we know what you're dealing with?

Crisis averted! I was able to remove the broken stud with a bolt & nut remover set similar to what rowingone posted above!

Onward with my ITB install!

Great! Just be patient and use some penetrating oil and heat when needed, they should come out with ease. I like to tap on the top of each stud with a hammer a few times to knock them free if they are seized and the vibrations help the penetrating oil make its way down the threads.

Ditto dg567. Tapping with a hammer helps break loose corrosion and get the penetrating oil into the threads.
