Engine oil leak diagnosis
On a 2.7 engine I have a major oil leak somewhere from the upper front passenger side of the engine. The thermal reactors and the air pump were removed years ago and this car has the external oil cooler up front. I have absolutely no compression loss or blowby between the heads and cylinders. This leak only appears sometime after the car is shut off and parked for a while, like over night. No leak is apparent with the engine running. I can drive 300 miles with no loss of oil.
When the car is parked what amounts to a pint of oil can leak into a catch pan after a few days. Any ideas? Oil tank hoses?, hoses for the external oil cooler?, valve cover gaskets? What else is on that side of the engine up high that could leak that much oil?
Thanks for your thoughts.
