Well there is another thing I was talking about 20pages ago:
You test it on cold engine, right???
So..... You got the point
It might show smth, but 105 vs 10C is a huge difference, that's why you see your pressure ok in the morning.

I think rear plate is super important bc it pumps coolant into the heads!
And if it has same exact crappy profile gasket as valley pan, so why wouldn't it fail??
