Re: Problem with my 156
50'000 miles since last change sounds about the average for a failure.
alfa have changed the recommended replacement interval to every 36k or 3 years, they just dont seem to have told many of their customers! its always worth arguing with alfa that if the car is fully alfa serviced then there to blame for not informing you of this change but few have been succesful on this front, some have managed to get alfa to agree a 50/50 settlement tho.
have you taken her to a alfa dealer or local indie? local indie your most likely looking aprox £1500 im afraid, alfa even more.
general damage when this happens is
- belts obviously
- variator (does the 1.8 have a variator?)
- bent intake and outlet valves (varies how many)
- damaged valve guides
in a worse case you could be looking at a damaged intake or exhaust header, replacement head, shot bottom end bearings... in which case either scrapping the car or sourcing a replacement engine may prove abetter bet, especially given the high mileage yours has covered.
when the garage is doing the work be sure to get them to check the bottom end bearings as these can become damaged and cause bottom end failure after a few thousand miles... NOT something you want!
other than that i cant say much. my belt went last year, cost was set at about £1400... that was new belts, tensioners, variator, all valves and all guides plus the head being reworked. was lucky to not damage the bottom end.
best of luck mate and keep us informed.
