Disaster has struck! Timing chain and/or chain tensioners have broken. Either way, the engine went "BANG" and died. The tappets no longer work, no compression to speak of and the hood is still down - so there is no doubt on the diasgnosis nor of my predicament. The questions are: - what to do about it. Rebuild .v. reconditioned unit - recommendations on a good supplier - cost .v. quality. The car is in Kent. The car is a W124 cabriolet E320 Sportline and is my pride and joy. Even though it has done about 150k miles it is still a baby - well perhaps a teenager - but is worth keeping either way! Clearly it needs urgent help and resuscitation - as does my wallet so please take care of both when replying. Any suggestions and recommendtions will be gratefully received.
