No, seals are cheap, engines expensive.......
Hi, The float valve is leaking through. The fuel can leak in the intake and down into the crankcase, where it dilutes the engine oil.
Dirty or stuck open needle valve in carburetor.
Inlet needle in carb sticking open; it runs in through the carb.
All oil senders can leak. Make and model makes no difference.
yes
when you drive with an oil leak the oil drips onto the road and makes the road surface slippery for motor cycles and other vehicles.
depending on what type of mower and who makes the motor it can vary. if it is a standard push mower you can either remove the dip stick/oil fill and dump the oil out there or look at the base of the motor for a plug or under the deck with the blade for a plug. if it is a riding mower there will be a plug at the base of the motor that can be removed to drain it
Float is bad in Carb or needle valve not closing causing fuel to leak into cylinder
There must be a crank case leak, or the oil pan plug is gone.
What makes you think it only leaks while parked. -
regular push mower oil
