    Hi Everyone

    Oil leak? on my Toro! Please help. Of course I didn't think to write down the serial number or anything (at work now). It's a 22" Recycler with a tecumsem engine, probably 2 years old. The valley of the top of the mower was full of oil last night. Cleaned up the oil last night and took photos this morning. I didn't check the oil level. It's probably been 10+ days since I've used it. I did check the oil last time/maybe time before I used it and dipstick indicated it was low so I added some to get it to the right level on the stick. It ran fine the last time I mowed...

    So what did I do wrong? Did I fill it too full? Should I empty the oil out and start over? Am I OK to mow with it?

    Either you have a carburetor float problem and the gas is getting into the sump, thinning out the oil, and leaking out -


    The square-cut o-ring at the bottom of the dipstick tube is cocked sideways, loose, or too well-lubed. If this is the case, remove the fuel tank, take the tube off the mower, clean the o-ring and put it back on. Hit the top of the dipstick with your palm to really seat it good on the o-ring when you put it back together.

    Spray it down good with engine cleaner and hose off, then dry it. See if you can tell where the oil is coming from.
