So on the first test drive it decided to burst my bubble. When the car is warmed up it won't idle without throwing a "low oil pressure" warning.

Was hoping that perhaps that was because the oil pressure switch was faulty, or not plugged in. However I checked it was plugged in, and then I swapped it for the switch from the other block.

For future reference this requires a 26mm wrench. It's also easier if you move the crankshaft sensor out of the way (secured with a 10mm bolt). Pro tips: oil will come out faster than you expect; have something ready to catch oil; don't use your head to catch the oil; have the replacement switch handy to put back in the hole and stop the oil.

After cleaning up the mess I went for another drive but the problem persisted. Sad, but on the plus side I now own a 26mm wrench. Next I'll try to mechanically measure the oil pressure at idle to see if I can figure out if it's a signal error or a mechanical issue. Don't really want to swap the engine again as much fun as it was......

So I hooked up the oil pressure gauge. I got this kit from Amazon as I wasn't sure what size the thread for the oil pressure switch was, and I couldn't find it documented anywhere.

Easy enough to hook up. It used adapter number 8, but since there are no instructions with the gauge I still don't know what size that actually is.
The included elbow made it much easier to install as well.

Then before I started the car my eye caught the coolant reservoir, which was empty.

I checked the oil level and it was way over filled, which is odd considering oil leaked out while changing the pressure switch.

Was thinking that perhaps the head gasket is toast, but wondering if the oil cooler gasket is damaged. Perhaps related to the bent coolant hard lines. Going to try switching out the oil cooler and gasket next. Really don't want to change the engine again.

I'm leaning to oil cooler, as it could easily have been bumped during removal/handling/installation in a way that may have damaged the seal?
