After all that, the block is effectively dead. Economically.
In addition to the head face damage, the main bearing damage on the centre bearing includes another crack in casing. Repairable? Maybe, but it would ned a line bore process, which just makes it economically not viable.
At least I've found out how to get a V8 front end apart.
So, now I have to decide what to do with the rest of the car. Rolling chassis, 1990 V8. Just wanting a new engine.
Of the engine, the following are salvageable-
Induction system
Exhaust manifolds
Alternator,
distributors
Heads complete
Oil pump (was showing good operating pressure)
PS pump
Air con compressor
These bits damaged-
Block, 2 cracks, and head face damage
Crank- main bearing journals 3(very bad) and 5(light scoring)
Ring gear/flywheel/flex plate 2 teeth missing
So, options-
Buy a short 3.6PT engine
Buy a complete 4.2ABH engine
