well - K-Seal arrived and duly added. Flat battery on the GTV, definitely no chance of starting on the key, so hitched it up to my pick-up. I have never had such a reaction when trying to bump start a car!
Towed it at 35 mph and nothing - no sign of life. Pulled in to discus Plan B, and clutch smoke was pouring out from under the bonnet! My guess is the engine is siezed and my Ranger just dragged it along!
And - when we got back home, in the empty space where the Alfa was originally parked - on the ground was a timing belt tensioner - siezed solid!
It really is ******! As a post above, I am not going to put any more cash into it, it really isnt worth it! Ebay here we come!
Thanks for all the comments and advice, but the time has come - and I really do fancy a Guiletta now!
