HI Pis-ton,
Thank you for advice. I got a $7.50 rotating wire wheel from Bunnings today, and installed it on my grinder and did some clean-up of the sealing surfaces.
I found some pitting corrosion on some of the seal surfaces that I maybe otherwise would have overlooked.
I also discovered that when knocking out one of the seized pistons last week, it left a tiny scratch up the cylinder wall in one of the bores. It must have been the end of one of the seized rings that did it.
Whilst I could have got this engine 'running' by slapping it together, I have decided to take the block to a machining shop. It will likely need an oversize piston.
Some of the small pitting corrosion was on the cylinder head towards the gasket just where the cylinder seal is, therefore I will need to have the head skimmed also.
Apologies, no photos yet. Have some that I will post soon.
Cheers,
