Oil consumption

[Geoff Dowdle]

peterg,
my guess is that if you measure the very top and bottom of the liners they will be standard as the rings don't come in contact with the liner .
If in the centre of the liners there is .003 to .005 the liners are well worn .

what is this centre measurement of the liner compared to the measurement at the top of the skirt at 90 degrees to the gudgeon pin .
It is only a guess but I expect it might be as high as .007 in compared to about .002 inch needed for those split skirt pistons.

If the pistons are in excellent condition you would then have to replace the liners & rings
or
buy a new set of .010 or .020 pistons and bore the liners to suit.
Either way it will need fixing correctly
