Help! What is making the oil leak?

[Berco 13]

I have an oil leak on my Kohler CH22 in my Toro 522XI (see video). I put in new head gaskets to remedy low compression. Then upon first start i had a large oil leak. It seemed to come from the aft oil seal. So i pulled the engine again and replace the seals. I re-installed the engine again today and the leak is still there. This is the leak now: https://youtu.be/pi382fXVXPQ What could cause it? I did blow out the air line from the fuel pump with compressed air into the crank case to clan out any debris. Could that have caused a leak this bad on the oil pan gasket? or another location? thank you all in advance!

have you done a compression test maybe the piston rings need replacing.

I have. I get 110 and 120 psi for the cylinders. It is not bad but not great. But it starts right up. The previous reading was 60 and 90. There is not any smoke when running and the oil level doesnt drop, so i feel the rings are good for now. I do not think bad rings could cause oil to pour out as seen in the video, but i am def a noob.

Not over filled with oil?

Depending on how much pressure was applied you may have blown out a seal or gasket.

Hard to tell from the video, I don't own any CH Kohlers but they do have a pressurized lubrication system and are OHV engines, is the valve cover gasket the point of the leak?

It is not. I filled it up slow and checked often to ensure no over fill.

I cannot determine exactly the location of the leak. It is not the valve cover. It just replaced both oil seals and head gaskets, so maybe the oil could be leaking from the crank case seal. I am running out of options of where oil could leak from so rapidly. I do have a new breather valve on order and will be replacing that ASAP as that is the prime suspect now.

Why order a new PCV valve before inspecting the old one, when a simple reed adjustment might cure the problem..

This engine has 1000 hours on it and i do not really want to pull it out again if the reed needs replacement shortly after. More of a do it while i have the engine out kinda thing.
