So I think I have found the oil leak. It is from the pressure side of the oil system.
I checked the transmission fluid and I was almost bang on with mt guess at 25ºC mark.
This morning I placed all the hose, wires up top that needed to be finished off, so with the transmission level close enough to road test and bring up to 80ºC figured it is time for a test drive.
The drive went rather well about 20KM total. For the first bit of the drive I drove it like I was driving Ms Daisy. Smooth steady acceleration and not going over 50KPH. Then I drove it like a normal person would do in a city drive with little traffic and finally I used the paddle shift and kept it back a bit not letting it get into fourth.
The temperature gauge needle was at the top of the 0 at the 80º mark on the gauge. Stayed there most of the time.
The engine sounds quiet, runs smooth and seems to want to go from my short little test drive. The car idled smooth at the stop lights.
I even used the AC on the last leg of the test drive. Once I get this oil leak solved I will get it up to faster speeds and be a little more aggressive on the throttle.
So it is leaking a decent amount. There was oil pooled up where the head bolts to the timing cover, down the front of the water pump and along the bottom of the pan. On the way back to my place the warning message came up low one litre of oil refill at service station. This is why I am sure it is on the pressure side. So about one litre of oil from driving around my parking lot Sunday, today's test drive and all the start/running trying to get the ABC working.
The picture of the oil cooler housing is my old one from my engine.
