"A nasty garage man put a ball bearing in the engine"
Discussion
Regarding the turbo dropping a ball bearing this would never happen due to the design and shape of the compressor wheel not to mention the intercooler, something defo doesnt add up that the owners not saying.........but defo not detonation damage, this is usually manifested on petrol engines on the edges of the piston crown due to poor fuel atomisation ie dodgy fuel injector and if left will quickly eat straight through the piston ring land and you loose compression.
In my time as a mechanic in renault/nissan garage we used to see a fair few engine destructions on the K range of renault engines due to timing belt tensioner failures, but the best on was a18 year olds "max power" 1.4 16 valve megane coupe.
He said once it was towed in as a non start that earlier in the day it sounded a bit rough but thought nothing of it.........he was chasing another car when it made a bang and cut out. Upon lifting the bonnet for initial inspection the engine was locked and wouldnt rotate, once timing cover was off the belt was just a pile of dust and broken strands of belt, yep one of the timing belt tensioners had seized solid.
A quick glance at the coolant bottle showed no water, removed the dipstick to see a high reading and alot of metal swarf, a closer look at the block showed a nice new vent hole created by the con-rod. With the head off all was apparent......... the timing belt has let go at high rpm, the piston came up several times smacking the valve to the point that it snapped off, then got duely smashed through the head into the water jacket allowing coolant into the affected cylinder, yep you cant compress water so it bent the conrod to the point where it bent and tried to lock up in the bore...............exit stage left through the block.
In my 12 years at the garage it was the best engine blow up I have ever seen, mind you the offshore boat I was on a month ago suffered a catastrophic failure of one of its 16 CAT 24v twin turbo diesel engines, number 11 piston/liner/head/con-rod were all well and truelly fubared, the chief engineer showed me a bucket full of metal chunks, but its wiped out the massive crank too. The engineers were scratching there heads as to work out how the fook the are going to get the engine out through the tiny hatch way, glad I aint doing that s
t anymore

t anymoreI know a certain chap who was going through a very messy divorce , His spouse wanted his pride and joy A TVR 4.2 Cerbera pristine .
it was probably worth 24k ?
He eventually gave in and let her have the car , but not before adding a tin of fine grain grinding paste to the oil .........
Which i think lasted about 2,000 miles before the engine was completly f.ked
I was also told by an ex Ford mechanics that it was regulary done on Fleet managers who refused to pay bills on time !!

Out of interest, other than rear mudflaps for a Mk2 75/ZT, what exactly are the parts you've struggled to get?
A 'perfect storm' of ever-harder-to-get parts (remember, insurers won't use pattern parts or used parts) [quote]
I see.
I was surprised in the comment originally, but you're (generally) talking about body parts after accidents., so it makes more sense.Rimmer Bros and X-part are still around,and there's now big availability in 2nd hand parts and upgrades via indi traders. Rovers/MG demise has resulted in some incredible used car bargains!
