^ good looking lift...

Z Fever Racing identified two primary causes of engine failure

1) the in/out were backwards on the sandwich plate adapter for the oil coming off the block, resulting in minimal oil passing that point and thus passing along to the oil cooler core and returning to the block... this explains pretty much EVERYTHING including a dead-*** engine... as it turns out, I have the mfgr of the sandwich plate adapter to thank, as the correct flow was opposite of the indicated flow... there will be pictures of this soon

2) normally the ECU would shut the engine down in the event of no/low oil pressure... if this happens correctly then item 1 above would be unfortunate but not catastrophic... unfortunately, a prior installer in the process of modifying the cooling system built a DIY wiring extension to provide more room for wiring going to the oil pressure sensor and another sensor next to it... one sensor gets +5V the other +12V (or something like that)... the two were swapped, thus eliminating the oil pressure signal to the ECU and thus bypassing the normal safety shutdown sequence involved with no/low oil pressure

Ah, the little things!
