Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Reported cause

As Sierra suggested, assuming it was the failed aos and you put a new one on the car, clean out the intake/tb and it will go away.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

My 996 has been emiting white smoke after hard drives for a while now, at first I thought it was my AOS, but I replaced the AOS two days ago and today I figured I�d go out on a backroad and have a bit of fun. A couple hours after my drive I went out and started my 996 and saw huge puffs of white smoke out of the exhaust. Could my car being catless have anything to do with it??

POST 2Original post

Pull off the throttle body ad look for oil in the tops of the intake runners. Did you check and clean them when you changed you AOS.

POST 4Original post

Easy to miss something. I just did a full rebuild and am breaking in the motor. After 400 miles the engine developed a bad rattle. thought I might have to disassemble it but it turned out the power steering pump pulley was not properly torqued and was the source of the rattle. What a relief it was something so simple. mark

Yep, when the oem Air Oil Separator fails and doesn't separate anymore, you get oil in every nook and cranny. The best is when you get oil in your exhaust and you get black smoke and flames out the tail pipe. Been there and done that. Consider the UAOS sometime in the future as a replacement. Sure, the oem AOS is cheap. But there is a reason it's cheap. As Sierra suggested, assuming it was the failed aos and you put a new one on the car, clean out the intake/tb and it will go away.

This is a source reference. Confirm exact model applicability in the original material.
