Why B****y ME !!
WHY DOES THIS HAPPEN TO ME !
First of all siezed engine
now just after failing SVA I notice this !! And ofcourse I booked my retest yesterday!!.
1 x Broken type 9 bellhosing
1x Broken Bolt casting on Engine - (different palce from G/Box)
AHHHHHHHHHH
This was noticed as there seamed to be a lot of movement on the engine while I was setting up the Carbs.
Had a closer look and notice the crack on the gearbxox ( top right hand looking to front of vehicle).
After that I also notice that the right hand engine to gearbox tab was also broken. (looking from g/box to engine).
Why is this happening?
Could this be distructive vibration from an unbalanced Prop?

Got any pics? If you need a bellhousing I have a cast one sat outside doing nothing except soaking up the sun.

is that rust on the crack in the photo showing the engine and box ? that would suggest that it's been damaged for a while. The crack on the
engine looks like it is a result of the other failure, no signs of fatigue or of previous damage.
hard to see from photos though!

No the rust you are seeing is the edge of the fly wheel. Both show very little signs of old crack!.
The engine one loos like it went first as it has managed to "polish" part of the face.
This happened about 15miles from home on the way to SVA. I know as I commented to my backup. That it was making a funny noise at speed, from the
drivers side.

mhhh
You could try to weld it with an arc welder and special cast pins/electrodes....
a couple of 100kilograms should do it.
Else i would just drill tap and make anohter mounting out of sheet/strip

looks like possibly the bell housing was warped putting excessive strain on the 2 points????

I would be suprised if the bellhousing had warped, something I've never heard of or come across before.
How many miles had the engine done? did you remove it from teh donor vehicle?
I've known vauxhall engines that have had broken castings round the bellhousing, never had any problems as long as all the other bolts are
intact.
It is also possible if the engine was ever dropped or knocked/damaged during removal from car, whilst in storage etc etc (hence asking if you removed
it from donor yourself or sourced it from a scrappy that probably wasn't that bothered!)
I would guess the bellhousing as well is just bad lucky unless the damage was done previously at teh same time, but unlikely seeing as the parts are
from sperate donor vehicles.
I'd just replace the bellhousing or patch it up for sva, if something else happens then I'd worry but its not going to cause a structural
failure and there's very minimal risk of damaging anything else - especially if you heard a noise befoer you realised anything was wrong.
all imho

Have had an out of balance prop break the bell housing on an old Avenger and also a bad clutch judder break the bell housing on a Citroen XM . Could
have been caused by misalignment of engine/gearbox , bent first motion shaft on gearbox and maybe previous damage if the engine /gearbox came from
accident damaged cars . I think Sierra's used to damage the gearbox if they were shunted from the rear ? although the ally housing at the rear
of the box would be more liable to damage

Why is your engine seized? If it's due to overheating maybe the expansion caused this cracks?
Are you a Mac user or a retard?

Not overtightened are they?
You didn't do one up fully tight and then another did you? Should all be done progresively like head bolts.

My first car did exactly that as the prop was out of balance. New prop balanced cured the problem.

Get the prop balanced! This thread shows what a prop breaking can do to the car, rather worse than breaking a few castings.
This guy was lucky! (page three for decent pictures of the devastation).

Just been reading the post linked to above.
Interesting to read that someone insists on grease nipples on their UJs. Very worth while. Had a 2.4D Hilux once. Front UJ dried itself out, due to
hot summer, dusty fields, me driving too fast etc. One day BANG! prop still attached to rear axle, whipped round and put a huge dent in the load bed,
fuel tank etc. Wouldn't want that a few inches from my leg! Having said that, mine isn't balanced and i shortened it myself! SHIT!
Planning on getting a new one made by south wales props once done SVA, then i can boot it with confidence
