Either the coolant crossover on back of head or .. I do believe there's a freeze plug just above the oil filter on side of block . Might check that out .
Ed,ITS possible its leaking from one of the steam tubes that is attached to the back of the cylinder heads. Yes you do have the optional oil cooler on your car,but the oil cooler is not plumbed into the cooling system in any way. Get under the car with a good flashlight and see whats happening.Be sure to have it jacked up safely. ed
Yea, if you had a leak internal to the cooler part, you would leak oil into coolant or vice versa, which is why the stock oil cooler did not last long as an OE option.SNM, First off you may be correct,but help me with this. One type of oil
cooler system routes the oil to an external cooler and then back to the engine,so I dont see how the oil would mix there. The other system that you show,it goes into the radiator side tank,if there was a leak in that case wouldnt you have the oil and coolent mixing into milky white stuff,in his video it appears that the coolent is leaking from the filter unmixed! Watta think,am I still missing something? ed
This was a major help - Thank you!Gates makes a oil cooler bypass hose p/n 18959, any auto parts store should have it. I have one on my car. If you want to go that route.
