Craig,

That would be a question to ask EBS how they determined they were in spec. To be honest, I've only had a very few sets of pistons and cylinders come back for eval and the pistons usually look like new and are easy enough to measure without much, if any, cleaning. And usually, if it's something like a recondition job - say a set of 4-cam piston and cylinders, I ask the customer to check everything first before sending to me.

If anyone has any suggestions on cleaning the pistons, don't be shy. I have a can of the old non-epa friendly parts cleaner in the gallon can with a basket in it that has to be a million years old. Just leave in overnight and the parts come out easy to clean with nothing more than a toothbrush.
