Has anyone stripped and rebuilt their Subaru 4 pots? I bought a set of "refurbished" 4 pots with new stainless pistons and new seals early last year and now some of the pistons are a bit sticky again, I assume the bores weren't cleaned properly during the rebuild so need to strip and clean them up, I want to re-use the stainless pistons so don't want to damage them getting them out, what's the best way of getting the sticky ones out? Also is it just a case of new o rings or should I get a set of seals as well?
