Oil Coolers

[jondee86]

The 4AGE has a relief valve built into the oil pump to prevent the oil
pressure becoming too high during high rpm operation.

The factory oil cooler is a bypass type with its own relief valve. At low
rpm the oil cooler relief valve is closed, and no oil goes to the cooler.
At high rpm the oil flow increases, the pressure rises and the relief valve
opens. Excess oil flows thru the cooler and returns to the sump.

An after market full-flow oil cooler will be more effective. A new
sandwich plate that returns all the oil from the cooler to the engine will
be required. Remove the factory plate and block off the return to the sump.

A system that includes a thermostatic valve to restrict oil flow to the
cooler at low engine temperatures, would be nice
