OIL INGESTION washer solution question of 'ringmiester...
The washer solution is as follows:
Take the vacumn line that runs between the intake and the oil separator.
Remove one end, find a washer that fits into the hose, insert the washer and re-attach the hose.
I have been told that it will reduce the smoke and oil getting into the intake. But I would not call it a "solution" more of a "patch".
But, I would wonder if this will increase the crankcase pressure at all?
Make sure the washer is too big to get sucked into the inlet!!!
I have found that keeping my oil level topped off increases the likelihood of smoking on startup at de events. I now leave the oil level down two notches and rarely have the problem.

It is truly a mystery to me how this would make a difference. I'm not saying you're incorrect, I'm just saying that I can't visualize it since we're discussing the PCV system.

Just a swag since I've never seen exactly how the internal 'dry sump' reservoir is accomplished. Perhaps a full tank provides a little more back pressure to the air/oil separator making the breather line to the intake manifold the lower resistance path. This would divert some oil going through the breather to the intake manifold. Maybe this is why putting a washer in the breather line reduces the oiling since it would increase the flow resistance to the intact manifold.
Lowering the tank level a tick or two could lower the resistance to oil flowing back a bit giving the separator an easier task.
I've read glenn's article about the need for a Motorsports air/oil separator for track cars running race tires and generating high lateral g forces. I assumed this would not be relevant for me, as I still have my OEM Bridgestones. However, I had a LOT of oil smoke for a LONG TIME after my AX runs yesterday.
The circumstances: each AX session was 3 flying laps on the Redwood Region's (Zone 7) AX circuit at the Santa Rosa airport. This particular circuit is more like a short track than a conventional "cones in the parking lot" AX setup. Between each 3 lap run, I sat in the idling car awaiting my next run. After my 3rd run of 3 laps, I slowly motored over to the parking area and shut down the car. I probably ran the car for less than a minute after the final lap before I turned it off. Note that the final turn was a right-hand sweeper, with the lap ending in the middle of the turn.
When I restarted the car 5 minutes later, there was A LOT of white oil smoke. So much so that the other AX participants were alarmed. The smoke persisted for quite some time, and finally diminished as I drove away. Note : my oil level is exactly FULL.
Does anybody think this could be caused by the same problem glenn (and mooty) have experienced? What other explanation could there be? Should I let the car idle for 5 minutes after my last run? Do I need to do the air/oil separator mod? Maybe I should just drain some oil out to get to the middle of the range... Help!
to avoid start-up smoke simply leave the engine running for a couple of minutes after your run. no more smoke.
Wow. Am I disappointed in Porsche. If they claim the car will 'take it and is built to race'
Why didn't this problem show up in testing. Or have they decided to copy the US car industry and test the car on the public! My old 911 smoked every time, if left to sit more than 2 days, regardless of how it was driven.
Love my C car and hope they come up with a solution. I have a scheduled DE with the dealer. Think I will put it on hold for now!

Unfortunately people are reading too much into this petition thing. The vast majority of tracked Caymans have not experienced this "issue".
Like a lot of stuff on the internet, "issues" get blown out of proportion. Of course, those who haven't had a problem (or are not unduly scared that they might have a problem) don't post anything.
While I've signed the petition, I've never had any such problem on track. And I've logged as many track miles as most anyone here.
So JDHC7, my suggestion is don't blow this out of proportion, and don't let it keep you from enjoying your car on track.
I got this issue today at the track.
Did 10 laps chasing my friend in his new M3, he will pull away in the straights and I will catch up braking and turning, mostly left turns in this track.
Went to the pits rested 20 minutes and when I started again , huge smoke , that lasted 3/4 of the lap .
Sacred the hell out of me , thought the engine was broken.
