Have a 5870 (999cc engine) has less than 5 hours on it with an oil leak between
the engine and generator only when running. Any ideas? cover? seal?

rear seal most likely

Here is the follow up. The engine is being replaced under warranty since it's not the seal. Apparently the crankcase is cracked. This unit is less than one month old and has only done weekly exercises. It's been apart 2 weeks now going on three. Not leaving me with a lot of confidence in the Generac product.

You should have confidence in the fact that they are taking care of the issue and stand behind their product. This was probably a casting issue and I am sure they produce millions of these engines with out problems. Generac pays their dealers well to assure good service for the customer. There are a lot of companies that do not. You could have bought a more expensive brand but they have their issues also. For the price point Generac can not be beat, even with their flaws.

Millions may be an exaggeration but I would put money on a million units in the field.

Updated information
The new engine is installed and the unit is now operational. Starts better and sounds better than the original. NO LEAKS I am happy again

Glad to hear. Those engines built on the 990 platform are the most reliable generator engines you will find. We have thousands of them in our service area, and the only failures we come across are from SEVERE lack of maintenance, or the occasional cracked block, or other odd failure.
