Hey Phill,
As you know, they are never done since you can always find something to change out or upgrade. In my case, I'm now having to get the oil cooler that handles the engine oil repaired. I've had a small previously untraceable (to me) oil leak for about four months and knew it only occurred while driving. Idling in the garage never caused issues so I was thinking it was an oil pan gasket or hole in the pan near the block. Turns out it was a leak in the oil cooler on the back side and it was dribbling down the matrix and then running beneath a panel where it dripped under the radiator. Part of why it took so long to find as I only knew there was an oil leak somewhere underneath everything where I couldn't get a light.
Already pulled and shipped off to a repair place here in the USA so hopefully it won't be costly. Certainly easier to fix than what I was dreading which was pulling the engine to look for a bigger issue.
Shot shows the oil cooler with a small line I put on it to cap it off. That allowed me to place it in a bucket of water and put air inside to see if it bubbled for confirmation it was the culprit and not a line.
These are a few pictures I shot while ratting around and tearing up the land on the other side of my house that day in 107F heat.
