I will wait and see in the morning what further investigation brings. I have very little patience when it comes to cars not working though.
The Alfa has one advantage I really like driving her, the GTI blew up on me and it was out the door as quick as the weather changes in Scotland. I also had a Chevy Blazer up till 2 weeks ago and spent a fortune on it and had it running perfect maybe 2 months before the next problem happened. My patience died after that and then the Alfa came on the scene.
Couldn't agree more wholeheartedly! Centurions were my babies, and they hold the record worldwide for being one of the most reliable and best designed tanks of that period. Still in use worldwide by some countries.: Now about a car marques reliability???
I am starting to think this is going to be terminal. I will have a chat with my wallet later today and see what it says
It shouldn't be too bad tbh, cranks can be ground to +0.030 and you can still get bearings. We have seen, and managed to save, much worse.
I would get the crank whipped out and run it down to your local machine shop, you'll probs be looking at somewhere in the region of about £250-300 for the regrind and bearings. They should be able to tell you straight away if it can be ground.
Right...an update on this. Head is off (work started Thursday evening, bad light stopped play. Continued Friday evening, rain stopped play).
The only slight issue was one of the cooling manifold bolts sheared, but I managed to wriggle it over what was left of the bolt shaft. Once the head was off, it came out with a pair of mole grips (phew).
The valves look ok. Contact seems to have been made between the piston and the head (the half-moon areas are clean on #3), but it seems to have avoided the valves.
I'm in the middle of cleaning the head up. Fate of the car still hangs in the balance...I know someone who knows someone who might be able to get the re-grind done on the Q-T, which might swing it in favour of a rebuild...
wait till it's dark and shine a torch throu each side hole, if you see light through any of the valve seals then you have a problem, the other way is the fit the plugs in tight, sit the head on the bench upside down and fill the cylinders with parafin, if the level drops the the valves in that cylinder are leaking
