Well done - just the sort of challenge kit car builders can overcome.

Subject: [Quantum Owners] 2+2 Engines - Update (If anyone's interested!)
Following on from my previous message regarding the snapped thermostat
housing stud and broken stud extractor, I thought I might as well have a go at
drilling it and the snapped stud out of the head.
After a couple of snapped drill bits, lots of swearing and a load of
aluminium shrapnel, the offending articles were successfully extracted from the
head. This did leave a hole though which was considerably bigger than the
original bolt hole which presented my next problem.
By now, I'd gone past the point of no return, so I decided to use a tap in
the hole to create a decent thread. The next problem I faced was the fact that
the bolt which was going to fit this hole was too big to go through the holes
in the thermostat housing. Even if I made the holes bigger in the housing,
there still wouldn't have been enough room to do up a bolt as the head of the
bolt would have clashed with the side of the thermostat housing.
I then had a brain wave!
If I could manufacture a stud which was two different diameters, I could
thread each end with different size die's - One which would fit into the head,
the other which would fit through the holes in the housing and leave enough
room to get a nut on to secure the housing in place.
I've attached pictures of the stages I went through to create the studs.
Once I'd finished them, I cut a small slice in the narrow end of the stud,
just to allow the head of a flat screw driver to fit in so as to help tighten
the studs into the head (I left the die on the thread so that after cutting the
slots I could clean up the threads so that the nuts would fit back on cleanly).
I made two of these studs as I had to drill two of the three holes in the
head - the original aluminium threads just seam to disintegrate. I'm very
pleased to say that the studs fitted snugly into the head and that the
thermostat housing has been re-attached, the system filled with water and
pressurised and no leaks so far. Very re-leaved!
Cheers to everyone who has offered advice and help,
Keith

Does anyone know what engines, apart from the standard 1.6 CVH, will fit
onto the mk2 XR2 gearbox in my 2+2?
I've managed to shear off one of the bolts holding the thermostat housing
into the head and after attempting to remove the remainder of the bolt, I've
snapped the stud extractor within the sheered bolt! Also a couple of other bolt
holes have stripped so I think the head has seen better days, even tough it was
reconditioned only 21,000 miles ago, as was the full engine.
Ideally, I want to take the whole engine out and drop in a complete
replacement, preferably something with a bit more power that the standard 1.6
CVH - If anyone has something lying around in the back of their garage that
they want rid of, please let me know :-)
Cheers,
Keith
