Hello,
i would recommend a simple compression test of every cylinder first. So you'll see if there is a cylinder that is out of specs, which will be a good indicator.
If you have a endoscope camera you can inspect the cylinders. But it is difficult to inspect the heads with a cheap one, because for that you need to direct the camera into the direction from where you put in the camera. Also you need to interpret what you see there.
The combines oil & water cooler is on top of the engine. There are round rubber seals below the cooler. Sometimes they fail. So if it is oily or wet there, this can be an indicator that a seal failed. Also the cooler can fail internally.
