I have a Grasshopper 616 with a Briggs Vanguard engine Model 356442 Type 0224-B1. I am not getting oil on the top end. I took the valve cover off and ran the engine I did not see any oil. Could you tell me what it might be the cause. Also what I need to do.

Sounds like you might have an oil pump failure.

Depending on the date code if the original oil is available or not. Pumps before 07101500 are NLA and you have to change both the pump and the closure plate.(crankcase cover) along with the associate gaskets.

I cannot find the oil pump in the parts list. Do you know the part number for the pump? Where do you find the date code.

Is there any specs. on the pump that I could get so I can check the pump? Is there any way to check the pump before I order a new part?

If the pump was dead, the motor would burn up in no time. Air cooled can only go so far.

There isn't a lot of oil in the valve cover like in a car engine for example. Especially a valve cover that is up high on the engine. Am I missing something here?

From the parts list it appears the engine has plain flat tappets and not hydraulic. It will not be pumping oil up through the lifters and pushrods like a car engine. The engine lubricatethe valve train by splash and mist. If the engine is running fine and not seizing the rods on the crank pretty sure the oil pump is working.

I have a oil pressure gauge and it shows 0 pressure.
