Oil leak - any ideas?

*Oops, posted this in the Cayman board by mistake - Mods please move or close*

Hi all,

Last week after discovering a wet oil patch on my driveway, I took some pictures under the RH rear of my 1997 Boxster.



It’s soaked under there – and drops about a tablespoon of oil after every journey.

After popping the engine cover off, I found the middle oil filler pipe to be wet above the flexi section, which after reading online seems like a common problem, caused by a failing AOS sucking the hose flat and cracking it. Although I do not exhibit any of the typical bad AOS symptoms, I will most likely replace this along with the filler hose, due to the unit being a 97 original (flat top).

My question to you is do the pictures suggest anything more sinister? That to me seems like a lot of oil for a small crack fairly high up in the filler hose.

Thanks

It is possible you have a faulty AOS. Cheaper to change it out and see if that's the problem. Clean up the underside and see if that solves the problem. If it's the RMS, the trans will need to be pulled to replace the RMS.

So why did you post in the Cayman section?

This is my train of thought at the moment. I'll switch the cracked hose and AOS as soon as they arrive in the post and see if that makes a difference.

If it doesn't, the car needs a new clutch anyway, so it will be a full RMS + IMS seal + IMS bearing job while the transmission is out.

& no idea how I managed that! I'll ask a mod to move this into Boxster discussion.
