10thou Oversize Pistons?

[heraldcoupe]

Hi im new on here,

I have a 1963 herald 1200 coupe and I am rebuilding the motor to fix a big end knock and piston slap. I just wanted to know if they have ever made 10thou over size pistons? Ive been told that you cant get 10thou over size pistons but the number on top looks like a 10(Pretty hard to read because its pitted) and it measures about 10thou bigger than a standard piston. The piston has been seized and is pretty scuffed up so its hard to measure.

Cheers

10 thou oversize is one of the regular replacement sizes, though they may not be currently available.
Std, +.020, +.030, +.040 and +.060 are currently listed,

Cheers,
Bill.

Cheers, ill remove a good piston and double check to see if it is actually 10thou o/s, then I may have to try and source a 10thou o/s piston from somewhere.

Surely if you have piston slap a rebore is on the cards in any case?

Cheers,
Bill.

Just needs a hone, the guy I got it off had overheated it just before he sold it and only damaged the piston, the bore measures, looks good and has no score marks so I was just going to hone it and put a new piston in so I can drive it. Ill pick up another motor to fully rebuild after I have got it going then swap them over and rebuild this one properly. I want it running for this summer.
