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

I have noticed an oil leak from the rear of my 3.2 boxter, when inspected there is a great deal of oil all around the oil seperator, on close inspection it looks like it spraying oil all over the left hand side of the engine. Can this item be replace or cleaned out, is it blocked possibly. It looks difficult to get of. Anyone had this problem, does it need fixing urgently Thanking you in anticipation of a quick rely. Megan

POST 2Original post

Replacing the AOS is relatively straightforward DIY job. Takes about 1 hour, working both from on top and from underneath, with the right rear wheel removed. You should also replace the "J-tube", although there is a different version of this tube for later 986's IIRC. Take a look at Mike Focke's Boxster pages for a better idea of what is involved, here: http://mike.focke.googlepages.com/airoilseparatorreplacement In some instances, a faulty AOS can cause major engine damage if oil gets into the cylinders and causes "hydrolock". If yours is only leaking externally, it may not be as urgent, but tread cautiously. Regards. Maurice.

POST 3 / ORIGINAL POSTEROriginal post

Just what I needed, husband had looked at the problem and there was a great deal of oil around the seperator, and the smell. Will now source replacement part. Thanks again for your help Best regards Megan

POST 4Original post

If you clamp a small pair of vise grips on the spring clamp at the bottom of the bellows it will make the hose easier to remove as it holds pressure off the stock spring clamp. Leave the small vise grips attached when re-installing and the bellows hose will slide on easy, then remove the vise grips from below and spring clamp will hold again.
