Some more updates have come through from Watermill Carriage Company. The main bulk of the work on the car has centred around the engine rebuild and the body, particularly around the front offside inner wings and bulkhead.
As mentioned in a previous post, the engine block was in reasonable condition. The images below show that the lips that the piston liners sit on are in remarkably good condition. There was very little residue in the cylinder walls which are prone to blocking from silt/rust etc.
The head has been rebuilt completely. It has new valves, valve guides and valve seats and has been converted to run on unleaded petrol. The head has been refaced – the marks shown on the bottom of the head are paint that will be taken off with a razor blade before fitting.
The bottom end of the engine has now been reassembled with a reconditioned crank (20 thou oversize), cam, followers, timing chain, oil pump etc. The valve gear was apparently in good working order so has been reused.
The ring gear and pinion has been replaced due to the damage from the incorrect starter. You can also see the new 87mm pistons and liners that have been fitted which will give an overall size of 2138cc which was one of the options available to buyers when the car was purchased new.
