Had an aftermarket manifold fitted today
and the mechanic broke one of the studs.
He says that the head has too come off and the stud drilled out and a new stud put in and wants to charge me for it 8-10 hours labour!!for something he broke.

is there anyway off getting the stud out without taking the head off.

You should be able to get a manifold stud out without pulling the head? Reasonable access no?

The stud should take no more than an hour, unless it turns into a complete bitch of a job.

You need something called an Eezi-out, you put a small hole up the centre of the stud and then use the Eezi-out (a left handed thread tapered hardened steel tool) to unwind it.

Erm, no? Why the hell would you even contemplate paying for his incompetence?

2nd vote for an easy-out, although if you snap that off then you really are in trouble!

Um, yes, head will definately have to come off for the spark eroder!

You need to know what you are doing with an Eezi-out, if you are a ham fisted oaf you will just snap it off.

The problem you have here is the exhaust manifold to head bolts are crap :hammer: this is a hazard of working on these things,
I have broken several undoing them even using penatring oil and heat, where do you stop if it has to come off then all you can do is try your hardest not to break it ,
Dont us a easy out as all they do is expand the bolt and it seizes in there, These are one of the worst tools to use.

Have broken a couple myself, same as mark, used penetrating fluid and heat but you cant odds it sometimes.

if it has snapped, you have no hope of getting whats left of it out without some major headache, trust me!!

i have managed to neatly weld a new stud onto what was left of the old one before with good results

 

[Mark Shead]

All my new engines get diff nuts and studs of the correct grade so this doesnt happen on any of my engines, It just adds cost

i reckon mitsi used special chocolate studs

the welding job was just a get out of jail for a non new engine

Another welding tactic is to take a nut, with a thread slightly smaller than that of the broken stud, and weld it directly onto the stud, filling the hole with weld.

I had manifold,eldow,downpipe and de-cat fitted. He broke bolt getting the elbow off as well.

from a legal point is he responsable for it
and have too fix it for free.I understand that the bolts can be crap but he broke it.

I doubt that very much, Most garages charge labour for however many hours a job takes, snapping a bolt/stud is a part and parcel of working on anything mechanical.

If you change something and a stud gets broken in the process, you charge for fixing it.

Not really, but he should be reasonable about it. No point in paying 8 hours labour (!) if he is a ham-fisted idiot and didn't take due care. Perhaps a timely reminder that if he want's your repeat business then a compromise can be arranged?

Mentioning the potential exposure (good or bad) that the MLR could offer gives leverage in many situations too.

Edit: I could drill out 2 or 3 4½" studs on a steam turbine outlet in 8 hours

 

[nippex]

looks like i'll have to reason with the guy tomorrow and see if he'll fix it for a reasonable price.

 

[daveo]

to get in about with an ez out you would still have to have access to the stud with a drill and if your mechy isnt sure of the job he could make things worse as others have stated.and if the studs are that crap drilling out completely should be quite easy,and even if whoever is is repairing the stud goes a bit off the mark would heli-coiling the hole to fix the new stud into place not be a viable alternative?.i have to do this in my work every now and again on gas turbines whose studs are like granite and the job takes an hour max,and the new stud goes in very easily.

 

[neverneverman]

studs

i snapped 3 off when i put a new manifold on! they came straight out with the welded on nut trick!! good luck! P.S **** happens!

 

[carlsevo2]

Two of mine were snapped off and same for me mig weld onto the end (be accurate) keep adding weld till there is enough to get hold off and undo with some grips, maynhave to do a few times but works great.

The mechanic is going to try and get it out with an ez out or welded nut method.
