Any ideas of the best way to go about tackling these, ive tried drilling through one and using larger size drill bits to increase the hole, but the only one that managed to get through was a tiny one, the others are just going blunt (HSS cobalt Dewalt drill bits :( ). drivers side needs 1 drilling out, one stud actually undone, and one nut came off as normal, passenger side how ever, 2 snapped 1 undone as normal.

 

I can not for the life of me get this damn drill bit to eat the stud that's in there, so at the moment, my clutch change is on hold. i want to get these elbows sorted while the gearbox is off the car as i have more room to play with.

 

I have a stud extraction tool BUT, last time i used one the damn things snapped in side the stud so that left me back at square one where by i had to then drill through that and the stud (when i did my blue car) so im a bit apprehensive about trying that again.

Take the elbows off and using a thin cutting disc on an angle grinder cut a V section out where the stud is it will then come out and when re-assebling use nuts and bolts with washers either side, works every time.

I had wondered why my last lot of elbows had that V cut into them, thought they might be after market ones lol, thanks jeff. shall give it a try in getting these elbows off (lets hope none of them snap as well)

I took my studs out and re-tapped next size up thread..hook my down pipes up with nice stout bolts now

you have pm

What i did is use a really thin 0.8 slitting disc u can cut right through the studs like jeff said but if you go straight through the stud should come out leaving the thread undamaged with tiny slit then u can just use a bolt with original thread..

 

 

And at least i know i most certainly have GT525 turbos.

 

dont try drill them with a hand drill mate..it will end in tears believe me.Need to come off and be clamped in a pillar drill..slow,hard and firm with cutting oil to keep them a round hole and not looking like a keyhole:biggrin:

Slit them like in pic, Screwfix sell 0.8 cutting disc go through it like butter lot easier then drilling.

Soon has u cut through there will be a gap in between two parts of the stud u can push one side out at a time, then put a bolt in cause rest of thread will be fine.

If u use thin slitting disc dont move grinder left or right cause they will shatter and try use some goggles..

I used a 800w corded drill, i started off slow and steady with the small drill bit, that ate through it and left me a nice guide hole, i then upped it to the next size, i started on that, on slow, but wasnt doing anything, so upped the speed to half, then full, by that point the bit had gone blunt and was glowing red hot, so got fecked off and lit me fag with it and took a break lol

Them slitting disc sometimes be glad to have crash helmet.

But for thin neat cuts there the nuts...

Trust me slit them and use nut and bolts or use new bolts.

Your be there forever drilling mate...

When you drill you need to libricate drill bit. Spray some water :)

or p on it while your drilling lol

Not sure that would turn out too well with the elbows still mounted to the car lol, might make the neighbors a bit shocked.

Cobalt bits need to be run at a slower speed vods, what size bit do you need?

all done now mate, used an angle grinder and cut V shapes in, and carried on till i cut the stud in half, couple of whacks with a mallet and they fell out.

Last set i did i got bolts welded back in,i cant recall the name of them but a rod is available for an arc welder to join different metals.

hrmmmm yes gold rods I think, allow you to weld mid to stainless, or cast etc(cast is a knob though as expansion needs to take place at the correct rate his requires preheating to do the job correctly) obviously it goes without saying you cannot weld aluminium to steel.

I don't understand what cutting the v into it does?

 

Do you the crimp them both together and hammer them through?
