Does anyone know if a frontal impact that puts pressure to the plastic intake can cause a water leak into the engine?
Replace core support, rad, a/c condenser etc and after one day of driving, overheated and I found the engine oil to be milky (water). Are there water passages in the intake? any info is appreciated.

 

maybe a cooling system pressure test would be the next step to isolate the problem.

 

no way.... that is not posible. I have removed several intakes on ecotecs and they dont have any connexion with the cooling system.... if the car overheated is more likely that you have a bad head gasket. Autozone has a tester on their loan-a-tools program OEM/Block Tester (27145) | Block Tester | AutoZone.com_ Good luck.

 

Need more info... How bad was the front impact? Any motor mounts broken? Was your cooling fan running? Was the cooling system purged of all air before you drove it?
