Tech : broken stud
Discussion
Tech help needed !
Took my newly bought Westfield 1600 X flow out for a very hard drive a couple of nights ago (all within the speed limit of course, ossifer !
) ... when I got back, oil was lagging out all over the place. At first I thought it was the scavenge pump housing, but it was actually just above that ... the oil pressure take off.
Some **** in the past has fitted a T piece for the two sensors, made out of brass. They've then overtightened it, slightly cracking it where it goes into the block. Noticing their c*ck up they've then slapped a load of goo round the crack, temporarily sealing it - until my exuberant drive the other night !
I pulled the goo off, and turned the T piece by hand, just to see if it was loose .... the thing just snapped off in my bare hand, it was brittle as anything !
This left the stud of the T piece still in the block, flush with the surface.
I've tried to remove the stud with a couple of stud removers of the "left hand cork screw" type (remember there's a hole through the centre of this brass stud, for the oil to go through. Both removers bit into the stud (brass being soft), but I ended up putting so much torque through them, I've bent and twisted both tools (and they were good quality tools .... and my neighbours .... oops !).
This thing hasn't even moved a mm. I've tried heat, and I've tried jolting the thing (with the stud remover). Neither worked. I've thought about a centre punch and trying to drift it round, but I dont think it would work .... access is limited, and I think the punch would just chew up the soft brass, rather than moving it.
I'm stuck. All I can think of now is of removing the engine drilling the stud out, and retapping or putting a hellicoil in. But this scares me silly .... for example, how do I stop loads of swarf and crap going into the oil ways ?!?
Or do I just abandon the thing, and take it to a professional ? (but how will they do it ?)
Help !

Help !
Snap-on do a very good extractor set that’s parallel. I've had success with these before when the corkscrew ones didn't work. The only problem is they are about £75 a set.
It should be fairly easy to drill because you've already got a hole up the centre to guide you. However careful you are some swarf will still get into the oil ways. You should use some cheap oil to flush it through.

You could try drilling several small diameter holes in the circumference of the stud (maybe with a hand drill or modellers drill) but not completely through (to avoid swarf in oiways. Then have a go at it with a small cold chisel to try and break it into a few large pieces which should come out more easily.
It's worked for me in the past (on my old crossflow westie).

Heat the surrounding block up with a blow torch, spray some freezer spray (get it from an electronics oufit, its also sold as chewing gum remover) on the brass bit & then use the stud extractor. The Snap on ones are a lot better than the drill bit style ones. I've got a few, if you mail me with the size you need I'll have a look & could post to you.
Just an update ....
Thanks everyone for your suggestions and help ! Got it out yesterday, but only after taking the engine out of the car. When the engine was out, I had clearance enough to use the Snap On tool, though it still took an hour or so to do ! Engine is back in now, and losely bolted up to the gearbox, just need to refit everything up ....
Didn't think that 12 days after buying a car I'd be taking the engine out ! :shakeshead:
