    I'm finding oil on the top of the deck any ideas?
    No visible leaks.

    Craftsman 21 inch only gets used on one property every ten days around customers pool.

    Thanks in advance.

    they usually use a tecumseh motor and the oil seal (from the dipstick to the sump) is usually the reason that these leak.

    more info is needed though

    what engine?
    where does it look like it is coming from?

    Motor is Eager-1 6.25HP Not smoking on start up or while running.

    First place I looked was the dip stick tube in the sump no leak there. Also went to tightened all bolts they were not loose.

    I figure over the weekend I'll have a go at it a little more in-depth inspection.

    that is a Tecumseh engine not Eager-1
    there is also oil seals on both sides of the crank and the breather to check

    Does it have a foam air filter element? If so, could the oil be coming from it? I know this may sound strange, but I've had it happen - on a 2 cycle mower no less. Until I figured out what was happening, I was really scratching my head over an oil leak from a 2 cycle mower.

    Bottom part of crank would be below deck.

    Yep figured that one out tonight.
    Any ideas where the breather is?

    GeorgiaGrassMan: Standard filter in a plastic tube of sorts no oil leaking from there.

    I'm thinking the last time I loaned it to a friend he overfilled it with oil. That being said I have changed the oil in it. No visible leaks as of yet. But we will see over the weekend. I'm going to let it sit.

    you can still have oil get on the top of the deck with a bad bottom seal.

    the breather is under the flywheel

    Basic oil leak locater maneuver.
    Clean top side of deck, engine, etc, not with soap and water, just clean dry rags/towels.
    Clean enough so there is no build up of any kind visible.
    Run it for a while, keep checking for signs of leak, there you go.
