All good mechanics can do it easily.

Just punch stud, drill, insert "easy-out", remove

Lenish the face (using a large and decent, bench belt sander) of manifold to remove any "bow", as this will cause more studs to break

[LTHLRB]

so drill a smallish hole and then just twist it out when their broken?

i am a mechanic, but i have never done these before so i am not confident, the mechanic who is helpin me is very busy and doesnt even have time to check my car.

whats easy out? lol

Try:

The Thread Doctor 0419 507 633

On site service to remove broken studs/bolts, but note the manifold/etc has to be removed. New studs are available from Nissan for a few dollars each.

how much does the thread doc charge per stud?

getting it all off isnt a prob, that will done in no time. But im concerned about the studs and stuff.

"Easy-out": Is the name of a tool, is available in various sizes to suit various sized studs. It is like a Tapping tool but with a reverse thread that stops half way. You drill a correct size hole, "tap" the easy-out (turn in a reverse thread), once the easy-out bottoms out on the stud it starts to unwind the stud out of the thread.

Detail Report:

- Use a centre punch to carefully make a dent in the centre of the broken stud

- Carefully drill into the stud, using an adequately sized drill bit. Make sure the drill bit goes in straight and square.

- Tap in easy-out and remove stud.

Due to the confinement of the engine bay, this is ALOT harder than how it reads, but is done on a daily basis by all good mechanics

around $20 to remove the remains of a broken stud.
