sandwich oil cooler adapter and oil cooler questions Options

[type47]

After track sessions this past weekend, oil temps as indicated by a dipstick thermometer (Mainely Custom item) indicated temps of about 252 F after 20 minute sessions (ambient temps in the 60's). The engine is a Euro D-Jet with 20-50 Brad Penn. The engine that was in the car when I bought it (not the same engine as in the car now) has a sandwich oil cooler adapter and the oil cooler is still mounted on the car and I think I will hook it up again. Two questions; first is the indentification of the outlet and inlet on the adapter; which is which or how do I figure out which one the oil should exit from and which should the oil return. Second, on a radiator style oil cooler, do you hook it up so that oil goes in the "top" and filters/goes down the coils and exits out the bottom connection or goes in the bottom and pressure feeds up the cooler and exits out the top to return? TIA

This morning I removed the adapter from the engine that was in the car when I bought it and identified it as (possibly) an Earls sandwich adapter with thermostat.

If you recognize it as something else, please let me know. Before I removed it, I tried to determine the tightening torque and got between 25 and 30 ft lbs. A little ball, spring and "stay" (for lack of better description) was lying in the groove and looks like it came out of the filter stand. Any ideas what caused the ball and spring to be pushed out of the stand?

I'm trying to determine the inlet and outlet connections of the oil cooler. The cooler looks like this Hayden but is about 13"x5.25"

the cooler is mounted such that the inlet and outlets are pointed upward, that is, the cooler lines are connected above the cooler (cooler is mounted inverse from as shown in pic). Best I can figure is it doesn't matter which is inlet and outlet

Without that ball check valve in place you were getting zero oil filtration.

Then I guess it's good it's sitting on a dolly in the garage and not in the car. I removed the engine 'cause my car wouldn't pass PCA track tech because of oil leakage. I removed the sandwich oil cooler adapter from the engine and installed it on the engine currently in the car. Not finished as on start up there was alot of oil leakage (IMG:style_emoticons/default/dry.gif) gonna go back under and tighten things up a bit. Need to repair before July 13th-ish; track weekend July 20.
