You should be running coolant (anti freeze 50/50 solution) in your exchanger.<br /><br />Anyway, a heat exchanger leak will not show up in the oil unless you have an oil cooler running through there too.<br /><br />Typically, oil and water mixing happens one of several ways.<br /><br />1. Head gaskets.<br /><br />2. Intake manufold and/or gaskets.<br /><br />3. Exhaust manifold(s).<br /><br />If you can, put some dye in the coolant and see if it ends up in the oil. That will eliminate your heat exchanger.

If it's Freshwater Cooled...<br />The Heatexchanger is Water to Water.... No Oil there....<br /><br />My 1st Guess would be the Intake Gasket has a Problem..........<br />Could be a Head Gasket..... But the Intake come off First.... Inspect it Closely.....<br /><br />Depending on How it's plumbed, an Oil Cooler Might be a Problem.........

The block might be cracked? Does the temp gauge work? Have you had it at a very high temp? Is the thermastat sticking?
