Mashed crankshaft - poss. new engine req'd
Discussion
Broke down in my chim 500 in France just over a week ago on the way back to Calais from the Dordogne.
It has just been delivered back to the uk (with some body damage incurred transporting it) and the specialist I had it taken to tells me it is bad news!
The retaining bolt on the crankshaft pulley fell out which in turn detached itself, pulling off the fanbelt and causing the car to overheat.
Although I stopped the car as soon as I realised it was overheating, the pulley seems to have mashed the crankshaft. I am now being told that it is probably going to result in needing a new engine (it has done nearly 18,000 miles).
Does anyone know if this sort of damage always requires a new engine???
I have been quoted a ballpark figure of £5,500 for supply & fit.
Any comments/suggestions???

Your engine may need a new crank or the nose could be turned down and probably be sleeved. There will be labour for a total strip down but the price seems high. You need an independent opinion IMHO. I doubt that the damage is that bad but haven't seen it. Got any pics of the crank nose?
Unfortunately I haven't got a picture at the moment.
I got a second opinion from TVR Power yesterday and they seemed to think that if the end of the crank is mashed it will need to be replaced. Apparently a new one is £900 plus 12 hours labour to remove & refit the engine. Whilst the engine is out there is obviously other work that may as well be done but it doesn't sound like it will come to anywhere near £5500.
I think I will get it shipped up to Coventry and get them to look at it.

Assuming the car did not overheat long enough to cause other damage then the very worse you could be facing is a new crank. There may be rad damage too but even if that was changed at the same time it would not be daft money. It would obviously involve new bearings, gaskets, coolant and oil etc but cannot see how you would arrive at anywhere near the numbers quoted. If you cooked the engine to the point of destruction then that will be another story.

Is the crank anything special or a stock rover jobbie. Reason I ask is a friend recently stripped several different rv8 based tiff engines and sorry to say this but the internal parts were quite mundane and stock rover items but with some mods ie shortened 4.2 pistons. He did say that all the work had gone into the heads and every engine showed signs of valve stem wear due to the lift on the cams being high. There is a tiff engine out there with a special crank but I'm not sure which one it is although I have something very similar on a 90mm stroke, ney better!
What stroke is the crank? Can you find out? You will probably be loking at a re-balance as well.

It's almost unbelievable to me that the pulley bolt can come undone. IIRC the torque setting for that bolt is about 250lb/ft. That's very very hard to achieve and takes a lot of effort. This doesn't seem to be an uncommon occurrance on the tiff either.
Does make you wonder sometimes, doesn't it..........

Scuse me posting in here but I paid £550 for a full strip and clean. £750 for the rebuild and then £550 for re-instal and commission. Other work done as well. But that was a full strip down and goodies done to the motor. The final bill was a lot higher but the crank was reground not replaced.
