    Guess I got some problems then.

    Cylinder 1 : 100
    2 : 95
    3 : 100

    Recently played with my prop pitch and was hitting 8550-8600. Was ripping up the river here racing a buddy and just held it pinned for a little too long. Right after that noticed a lot of oil puking out the breather. Can see smoke comming out it and when you pull the dipstick comes from there too. Funny thing though, it still feels like its running strong as hell.

    Most engine manufacturers (automotive) won't even give you a spec now, they just tell you that all cylinders must be no further appart than a certain number. If yours are that close, you should be good.

    All motors run good loose. Problem is that loose is just before KABOOM. I think your experiencing excessive blow-by. Likely culprits are low oil pressure and/ or running lean.
