740 & 760 230 Oil Sender and Oil cooler
Hey guys, just a few of questions regarding oil supply for red blocks.
Easiest question first: where is the oil pressure sender in regards to flow - is it before or after the oil filter?
The stock air oil cooler mounts long ways vertically - one fitting at the top and the other at the bottom. So after cool down when the thermostat is opening, does that mean majority of the oil drains out of the cooler back to the sump?
It seems to me that way. Thus every cold start the pump needs to fill the cooler and lines? What does this do to supply delay for start up? Furthermore, I assume in the oem sandwich plate the thermostat in its open position does not block of either direction, ie flow is allowed to the filter or cooler. If this is so, wouldn't majority of the oil go in the direction with least resistance - the empty cooler and lines?
It all works fine obviously... But I'm trying to add in a relocation and cooler setup so these questions are coming to mind. The best orientation I'm finding to mount my cooler is the same as stock, but according to 'correct' cooler orientation, the stock setup is a big no no. I've considered including an anti-drain back valve but I think that's a little convoluted and would add a small restriction...
