However, not one single manufacturer requires the residual oil to be flushed out during oil changes. Trust me, I've looked. I've been on google for the last 30 minutes searching for something. (if anyone does find something, please post it)

Then again, its your car. Do whatever makes you happy I guess. If I had to put my best educated guess on it, I would replace the oil cooler entirely with every engine rebuild in a race car (race engines typically last 1 season) and every 50,000 miles on a street driven car.

I more so feel better about it being I track my car and I feel that all fluids should be changed in full before and after my track days. Minus maybe the transmission and diff. But more than likely I would still empty all oil after two or three cycles when DD. So I guess we'll leave it at that.

I recently, last fall, switched from the modshack fittings down cooler to Z1s fitting up 34 row. I'm not going to worry about the tiny bit that gets left in between oil changes. minus the lines, its probably 8% of the oil in the system, and I really don't think its that big a deal to mix slightly dirty 8% with clean 92%.

But then again, I'm just waiting to blow the engine to do an LS swap.
