Sourthern WI | When you go to your dealer, pull up the lubrication circuit schematic in the service manual. Notice how there are 4 head bolts which have pressurized oil that go around them. Pull those 4 bolts, clean the holes out really good, pressurize the cooling system with shop air regulated down and let it sit for a weekend. Come back and look to see if those holes are filled with coolant. Typically leakage there results in oil in the coolant instead of coolant in the oil, but there's a chance coolant could be weeping through with the engine off. It's an easy thing to check and is a not so intuitive place to look. | |
