Engine Oil Cooler Gasket Weep and Oil Seepage
ModerateEngineOn both 2.0-litre petrol and 2.0-litre VCDi diesel engines, the engine oil cooler assembly and its rubber sealing gaskets are prone to degradation. After prolonged exposure to engine heat cycles and oil pressure, the elastomeric gaskets harden and weep engine oil down the side of the engine block and oil filter housing. If neglected, oil seepage can contaminate nearby coolant hoses, degrade auxiliary drive belts, and result in gradual oil starvation.
Oily burning smell entering the passenger cabin when stopped in traffic, Oil dampness and wet grime coating the oil cooler mounting flange and engine block, Small drops of fresh oil visible on the driveway or garage floor beneath the engine bay, Oil level dropping on the dipstick between scheduled annual servicing
- Inspect the oil cooler housing adjacent to the oil filter assembly for damp oil trails and pooling
- Check that nearby rubber coolant hoses have not softened or swollen from direct oil contamination
- Verify that the engine undertray is free from pools of leaked lubricant
