While checking the oil on a 1650 with the Kohler K341, I noticed the dip stick/oil fill tube looking like a 20 year old dryer vent. It had a lot of dust and fine plant debris stuck all around the inside. This motor was recently overhauled, and all the internals including the fill tube was spotlessly clean. The only thing I can think of is it's very loose around the crimp that holds the handle to the measuring stick and it's leaking there. The O ring is new and tight, but the piece it's on flops around a bit. It's mostly dirty to about 1/2 way down. I'm pretty sure the crankcase breather is OK as that was all clean too including the foam demister and hole in the tappet chamber.
