Got my engine back from westward engineering.
Nice chap to deal with
Bored out .5mm, 0.003 P2W. Honed, decked and cleaned.
Rings fitted and gapped, and ordered, 1 - 4, 1 being at the front of the engine.
Also sprayed the block.
Masked it up, first blew dirt off with air gun, then degreased it, then wire wool, blew that off with an air gun, degreased, and then sprayed with Halfords Very High Temperature spray paint.
Went well..
Finished product: (Stuck on a new oil filter as found it the best way to cover up the oil filter hole)
