Re: Advice on Bottom End Problem...ooh eer
As long as the crank journals look nice and shiny, and not metal to metal and scored, you should be ok.
If there is damage, then your looking at a good deal of time and money. I've just remembered that an engine I took apart which had bottom end failure (I needed the block- don't ask) the crank pins were all still good. I think that is encouraging.
If it were to need taken completely apart I would estimate 3 days labour (24 hours) for remove and install and strip and rebuild. If labour is £30 per hour, that alone is £750+vat. You would need parts, and specialist repair work as well. A crank polish or re-grind and hardening with new shells sized and fitting should cost £100-£300+vat. There is a fair difference in work involved. Finally, a gasket set + fluids, possibly a new oil pump, maybe an oil/coolant heat exchanger should cost £150-£400, again +vat.
Ok, these are garage retail prices, but it could add up to £2000+. That should be worst case senario.
If you can remove the engine yourself, that would save £250, and maybee more as you would change the oil and fluids yourself (or your friend would). Perhaps the pump and heat exchanger could be cleaned (probably inadviseable, but the engineers would advise), that could save money. Cut to the chase, if the engine needs to come out, however it is done, and whoever does it, it will be £1000.
If the sump is removed, and the crank journals look good. Then best case senario is oil, filter, shells and gasket sealer. Don't use cheap shells, but most auto machine shops would suggest higher quality ones anyway (when I rebuilt mine, I used much higher quality internals), but the parts total may not exceed £150. To have that done by a garage, add another £100.
Therefore, it could cost somewhere between £250-£2500. When it's read like that, it's not a very accurate estimate, but it hinges on seeing the crankpins first. In the meantime, do not start or run the engine as this will only increase the chances of needing major repairs, and it could increasse the cost tenfold.
