Recently picked up a Spider engine with 30k miles that has motronic pistons/liners and was going to reuse these in my 74 GTV as a budget rebuild. The pistons look good but the liners show water stains and some minor pitting.
Anybody have any luck honing water stains out? or should I just get new liners?
This was the worst one, the others look fine with crosshatching visible.
Thanks for the input-

Run a ball hone through it and see if it cleans up.

In my opinion you will need new liners.
