Customer Question
Hi I have a...

Hi I have a Toro 421 QR. The engine starts ok but when running it blows all the oil out of a tube near the valve cover. I then checked the oil and there was none. No sooner had I begun pouring fresh oil in, when it starts running out this same tube. I'm guessing the tube has to do with crankcase ventilation. But why is the oil running out?

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Shut off value? Yes. Fuel is clean.

Mechanic's Assistant: Do you plan on doing the work yourself?

If possible yes.

Mechanic's Assistant: Anything else we should know to help you best?

Where is the shut off value and why is the oil running out?
