Replace a cylinder sleeve / liner.
Moorey:
Have you been going to Ikea to get your quality measuring instruments.

;) In all seriousness, I will obviously have that done at my machinist. The block needs a resurfacing anyways, and I wasn't planning on buying my own resurfacing machine either (I don't want to use the DIY method with glass or wood and grinding paper).
I did check fitment without having rings installed. The ovality is quite clearly noticeable. In the right direction (IN pointing to inlet port) the piston seems a bit on the loose side in the "new" lining, compared to other linings. If I turn the piston 90 degrees in the bore, it starts to pinch a lot.
The big question will be how big the budget is going to be to get this engine sorted, as I don't have a purpose for this engine now, since I just installed my fresh Big-Bore 466 engine.
If it indeed requires a new piston kit and a re-bore, I will probably shelve it again, but this time in a clean and dry spot.

Those are again very usable tips.
Did I mention already that I love these forums? So much wisdom is shared ;D
Bryanj:
You can actualy get a bore gauge on ebay for less than £30 then a 25 to 50 micrometer
royhall:
Have you seen the £30 bore gauges off eBay Bryan. You would use it as a tyre lever, you get what you pay for. I was going to buy one until a VMCC member showed me the one he had bought, don't bother with them they are shite.
