AIR/OIL SEPERATOR

[machjim]

Can a backyard mechanic like myself remove and replace the oil /air seperator.?? The dealership wants 100 dollars for the part which I am sure can be purchased cheaper elsewhere...

My Boxster has just a little oil smoke when you start it..I have read that is a sign that the seperator is on its way out...when it does go it will billow smoke in a big way...

Here is a DIY on replacing the AOS on a 986.

After reading it, you should be the judge of whether or not you can perform the procedure - since you are the only one who knows your abilities.

Also I encourage you to spend a few minutes with the search feature on this forum to locate some posts about how to properly diagnose the AOS.

It could be that your problem is not the AOS, and in those posts that you can find with the search feature there are plenty of definitive methods to validate whether your AOS is bad or not.

A little oil smoke can be common in these cars. The way I understand it, the horizontal configuration can allow oil to seep into the exhaust and cause smoke on an initial start. A bad OAS will cause poor performance of the engine in general.
