Was just down stairs working on the oil cooler (found out it DOES need a gasket between the cooler and the block like I assumed from the start but is not listed in TheMan's instructions)... and noticed that the little port that comes from the block, and the port that goes into the oil cooler are on complete opposite sides of one another when the cooler is oriented the way the lines fit to it... thought that was odd!!! Would think you would want them lined up for least amount of restriction... but apparently not quite! or it is to force it through the cooling vanes etc.. so dunno.. but odd.
