I also have a thermostaticaly controlled cooler. the thermostat is loacted in one end of the oil supply fittings of the cooler. i got it from mr cool. looks exactly like the hardin marine one. anyways i just want to make sure it is all plumbed correctly. does it matter how oil flows through the thermostat?
This is the bible of oiling system plumbing-

post 5 has a pic of the exact cooler i just bought. but all of my lines are 1/2 inch not like what he was showing above.
If you have any 90 degree right-angle fittings, take this opportunity to replace them with sweep 90's. Also, there are lots of different AN/JIC (37 deg) fittings. I've seen 3kpsi and 10kpsi fittings on fuel lines and oiling systems. They look great and they're durable. But the internal restrictions are engine killers.
The line on the left is your standard low-pressure AN. On the right is 3kpsi. Note the the difference in the internal passages. Although the same size, the line on the left flows less than a third of the one on the right. And your system will only flow what the smallest restriction allows.

there are no elbows or anything. the hoses are formed for the angles and look to be 5/8 I.D. there are two straight fittings into the adaptor into the block. the hoses are formed and they have a bend and they go upward to the cooler and filter adaptor. mabye i have a beefed up oil system before hand. but yeah, no elbows. just 4 fittings i need to work out. the one from the engine to the cooler... and from the filter housing back to the engine. just wondering if it makes any difference in which way the oil flows through the cooler. due to the fact that the thermostat is in one side. i should post some pics of what i got. i hink you will be surprised. the thread that you refrenced was really informative but all the things he was showing on the factory gen 6 looks nothing like what i have.

Ok, i ran the line fron the center (pressure) to the filter and then ran the return from the filter to the side of the cooler with the t-stat. i ran the other line from the opposite side of the cooler without the thermostat back down to the return to the engine. i thnk i got it right. i was priming the engine and this time the drill would slip on the shaft of the tool. must be a big load on the drill or something. there is oil in the filter and all looks good but i am not getting to the point of seeing it after the cam to the distributor.

The center is the return and the outside is the pressure.

Flow the oil against the flow of water.

The flip side is to protect the engine from the cooler if it fails or releases anything.
