Finally got around to assessing the damage, knowing pretty much what I would find. Stripped the engine and removed the head, 8 bent valves, basically all the inlet ones. Priced up replacement valves and all the other work and parts involved and decided to get myself a complete working replacement engine. This ‘new’ one would be then rebuilt as much as possible , cleaned and fitted - so the hunt began for a suitable donor car.
Found a lower mileage S (87K) that was really shabby, lots of rust and only suitable for parts:
Got it home and removed the engine, as below:
Stripped it down and replaced the following:
Cambelt and balance belts
ALL belt rollers and tensioner rollers
Head gasket
ALL cylinder head camshaft box seals
Balance shaft oil seals
Camshaft chain
Camshaft chain tensioner pad
Rear main crankshaft seal
Other engine gaskets and o rings - as necessary
Exhaust manifold gaskets
Thermostat
Engine mounts
Oil cooler seals and gasket
Complete set of Beru spark plug (EHT) leads
Spark plugs (copper)
Distributor rotor arm and cap
While doing that, I extensively cleaned the engine, repainted components and inspected things like the water pump (it appeared to be a replacement with no leaks and a good bearing). I had noted the oil pressure on the long drive back from the PO and it was good, so decided not to do the rod bearings.
Then replaced the following clutch components:
Clutch pressure plate
Clutch plate (friction)
Clutch thrust (release/throw out) bearing
Pilot (spigot) bearing
