Hi. Thanks for asking your question and requesting me. I will try and help you out.
Yes that is a little low for this engine. It should be up around 40 minimum at that RPM. There are several things that can cause this. They are:
Engine oil level is low.
Engine oil is contaminated with fuel
The engine oil bypass valves are open.
The engine lubrication system is open.
The oil pickup tube has a leak or a restricted inlet screen.
Please reply back if you need more help or have more questions. I am happy to assist.
