I was thinking of fitting an oil cooler before I head to the track again since oil temps were WAY high last time I was out there.

The thing is, I don't really have room or want to get a kit or relocate the filter as it just makes more failure points.

My question is since the oil cooler would be above the filter/sandwich plate, when you undo the filter, the oil from the cooler would also drain. This so all good and well for keeping oil fresh, but it means that the oil pump would have to fill up the cooler again before the rest of the motor gets oiling.

The only alternative I can think of is to relocate the oil filter to higher than the cooler (but then you never change out all the oil) or to take off the cooler and sit it lower than the sandwich plate so it doesn't drain out (hassle). Guess if I was crazy, I could always undo the cooler hoses and fill it up with a funnel before I filled the engine...

Thoughts people?
