On many old British cars the con rods need to be installed so the little squirt hole sprays a mist into the bore, and up to the wrist pin on the up-stroke.
As the XK con rod as no such squirty-hole, can I assume there is no left/right?
Oh… Big end down though, right???
Re-machined. They were .0015 ovaled. Plastigage now shows a solid .0015 on all rods/shells now. New pin bushings too. Sweet.
