hi all
as the title suggests iv blown up the roadster have not had chance to fully inspect the damage but i judging from the size of the hole in the crank case id say a rod has let go....
not sure of the cause but when i stopped and checked the engine temp it was about 105C so there was a cooling failure which probably was a contributory factor.
Anyway on the upside that gives me the chance to put something different in if i want, i may replace like for like which would cost about £600 or i could swap for the Volvo inline 6 i have lying around which may be a little more expensive and quite a bit heaver but would make a bit more power and would get the dam thing out of the way and put it to some use.
