When I did the first oil change at 525 miles, I cut out the pleated element from the filter for a look-see. I saw only a few pieces of metal shavings, but was shocked at how much orange and blue paint-like flakes were caught in the filter. I've no idea where where that all came from inside the engine, but it was quite the colorful arrangement. Also, several bits of the silicone sealant Honda used to assemble the engine. I shudder to think that all it would take is one tiny piece such as this to partially obscure an oil passage to cause all sorts of damage over time. Does all the oil the engine receives pass through the filter, or is it a partial bypass design? If the filter were to plug up entirely, is there a safety by-pass valve in the engine, because I don't see one in the filter?
