Coolant dripping down from just above the oil filter.... was my first
sign... the oil cooler is aluminum and was corrode with a small (pit)
hole.... but I was NOT getting oil in my coolant... it could be yours is
pitted somewhere the two fluids exchange heat, allowing a cross
contamination... only a suggestion.
