Sorry, Tuesday they fitted a new battery and the car started, but there was no oil pressure.

Wednesday - Sump came off and they found that the oil had turned into mud. oil system was flushed and pickups etc cleaned out, they then started again and there was no coolant circulation.
They found the blockage was in the block itself and flushed the coolant system.

While the sump was off they video scoped the cylinder walls from the bottom and found no scoring, cylinder 2 was slightly blue'd from the heat.

I collected the car yesterday, but it was extremely lumpy on idle and did not accelerate properly at all. I got home and replaced all 8 sparkplugs (what a job!).

Now the motor is running beautifully, but still has a bit of a lumpy idle, I suspect that the Idle control valve is a bit jammed up, so I'll grab some carb cleaner and clean it out.

Otherwise the only thing that is bugging my now is what sounds to be a noisy lifter, although there is thinner than usual oil in the car right now, which may be causing that

I will be running an engine flush again on Monday, and oil and filter will be replaced on Tuesday, this time with thicker oil for the older engine.
