Hi Folks. Looks like I have oil leaking at the bottom end of the dipstick tube. I've wiped it off and will run the mower again to confirm it is the seal. I'm in Sarnia Canada and it looks like a replacement seal (part # 692296) is a whopping $25 which sticks in my craw. Briggs and Stratton sell them for $3.50 but won't ship to Canada. There is an industrial supplier in town and I am tempted to drop by and see what they have in the way of O-rings. I need to ensure that the material will take the high temperature but am not sure what that would be. Also needs to be oil resistant.

Your thoughts would be appreciated.

Sincerely Grouseman

I google part # for OEM part & best price.
HAPPY FATHERS DAY! https://www.partshouse.ca/oemparts/partsearch/briggs_stratton?partsearch=692296
$24 now in Canada to resolve an oil leak with OEM B&S part, drive across the border to B&S parts store or wait 6 months & recheck price which will likely double like gasoline, groceries, & all consumer goods. I fully understand your frustration & have been there many times, try taking measurements of old o ring with caliper & look on Amazon for heat & oil resistant “o” rings your size.

Thanks but with shipping it still comes to $24 for a simple $3 O-ring

It doesn't get that hot. A harbor freight o ring will work.

I'll bet the existing red one is high temp silicone but still a good idea.

find a friend who has an address across the St Clair river from you in the USA. Lots of Canadians keep a PO box on the American side for that reason. It is the shipping that makes it so expensive. The river is only 1200 feet wide. Surely you can travel that far.

If you ask nicely there are several workshop owners with a paypal account who would be happy to put 1 or 2 in an envelope & post it to you
Parts suppliers like Jacks Small Engines will ship via USPS which should be a lot cheaper .

A standard -115 Viton or Silicone O-Ring will work ... you can find these at any industrial supply house or amazon.

My B&S on my 1996 Lawn Boy 10517 was leaking at the same spot.

We have O-Ring stock where I work, so I matched up the original O-Ring to a -115. We have both Viton & Buna-N, but the Viton is higher temp so that is what I used. The Viton we have is 70 Durometer which seems to be a little firmer than the original silicone ... whether a firmer seal is better or worse for the application I don't know. Leak has stopped so that is all that matters to me. It is not too difficult to replace so if I have to change it again sooner than an OEM B&S seal would last, no big deal.

He is only a couple miles (literally) from Wadham's Equipment on the US side, or Mikes Small Engine Repair on his side.
