Thanks for all who joined the conversation about the Ipad and which software for flight planning was best. I have taken the 30 day trial for Foreflight and we will see what happens.

I have another subject I would like to bring up about engines. Yesterday, while going through my conditional inspection at my local AP shop, we found aluminum shavings in the oil filter. With that I elected to pull all four jugs to have a look. What we found was wear of one of the piston pins and some scoring of the barrel. One was very noticeable the other three were slight. Not wanting to take the chance of further damage, I have elected to take them into Penn Yan Aero for work. I dropped them off today and Penn Yan said that at least one of the pistons would need to be replaced but he thought the jugs would mill up OK. Now I have a decision to make. I have always wanted to put in high compression pistons to get that additional 20 HP, if that is true. I am told that the increased compression will not put any extra stress on the engine. What I don’t know is what other concerns I should have before making my decision. Would it have any effect on cooling? Do I need to use a different plug? Does the higher compression have any effect on starter? Any education from you engine guys would be appreciated. Thanks
