1999 C4 AOS Quetions
Could the oil and water mix in my engine actually be caused by a bad AOS unit ?
One tech article mentions disconnecting the coolant pipes and hooking them together to by-pass the AOS as a test Anybody have any additional info. on this procedure ? Are there coolant pipes (hoses) connected to the AOS I am not sure that I see them in the diagrams of the AOS Need some sage advise on this one thanks |

Before even thinking about trying to by-pass the coolant lines, you need to know that even getting at the AOS on a 996 can be a bear, so if you think it is leaking, just change it out rather than try to jury rig a by-pass. It can be done with the engine in the car (http://www.renntech.org/forums/tutorials/article/238-air-oil-separator-replacement-aos/), but it is easier and quicker to drop the engine if you have the facilities. That said, judging by your other thread about the oil cooler, you may have to seriously consider that you have a cracked head, which is more common than and AOS intermix.

Wishing, Hoping, Planning, Dreaming etc... Dusty Springfield was on your side. Maybe it is the AOS.
