I posted this in the 6.5 forum, but didn't get any definite answers, so...

I just noticed that the ports for the oil cooler are plugged on my block. I know that the company I purchased it from had test run the engine before they sent it. This brings up a question about the oil passages in the block.

If oil circulates without an external cooler in place (plugged ports), that means the oil can bypass the cooler. With a cooler installed, does all the oil go through the cooler, or just a small %? Can anyone tell me how the oil passages are routed in a 6.5 (1997 with the piston sprayers, if that makes a difference).

Thanks!
