B80 Oil leak

[jdwheelhorse 0]

I just got home and was thinking about cleaning the engine up and I noticed this...

If you look closely, what appears to me to be engine oil is running down the front under the carb. I noticed a seal thats there and maybe its bad?

So heres my questions/thoughts, It could be because I just put 5w 30 in it recently and maybe overfilled it a little (which i dont think i did) or its a bad seal. So does anyone have some numbers of the seal and would a toro dealership be able to get one?

Thanks

I have a 1974 B80 4speed 8hp

Looks to me like it is coming from the fuel pump gasket.

Is it available from toro? I can look on the master parts list later I guess.

Thanks.

yeah the green paint job is getting on my nerves. the genius who did it painted over all the engine serial numbers and makes everything really difficult.

I know that the fuel pump for the B-80 8-speed is the same as my B-100 (K241s).

The original metal fuel pump has been replaced with plastic, but the gasket is still the same. Check with Kohler.

But since I don't know what engine you have, this info may be bogus for you.

You might also have a leak in the pump itself. one of mine started leaking oil around the pivot pin the pump arm pivots on. Try cleaning it up then running it to see if you can isolate the leak.

Edit...the plastic pumps I have found use a red o ring like seal instead to the old flat gasket

JD,

The Kohler gasket pn is 2504110. $1.05 on the Kohler website. This is a flat gasket.

You can also get a gasket at local auto parts!,Rick

Make sure your crankcase vent is clear. I have had this problem and oil just poured out of the fuel pump.

where is that located? is that the mesh area on the crank case?

Look just above the fuel pump. There should be a metal plate about 1.5 inches by 3. should have a rubber hose coming out of it. Take the cover off. There should be a drain hole in teh bottom of teh unit to let accumulated oil run back into the crank case...make sure it is clear and that the breather filter is clean....
