oil cooler cleaning?
I just recently spun a bearing and now I just got a new 2.3 stroker. I was wondering if just cleaning the oil cooler out in a parts washer and then running some gas through it and then finally rinsing it out with water is good enough?

You won't like this answer but you should throw it out. You will never be sure that everything is out of it. Replacements from the factory are expensive so it might be best to consider something aftermarket and do AN lines from the filter housing. It's simply not worth the gamble.

I still find it unusual that people will risk several thousand dollars on a motor build to run a used, possibly contaminated, oil cooler and get the old metal particles that no one can guarantee that they got out of the oil cooler in their new engine. The size of the particles and the nature of the oil cooler make it impossible to clean all of the contaminants out of it. The practice of looping the oil lines to route the oil back into the motor and bypassing the cooler has been done for a long time on built motors with no ill effects. This is much better than risking the motor on a "cleaned" oil cooler.
