zcacogp Posted March 29, 2022 Share Posted March 29, 2022 Guys, Small but annoying one here. My 987.1 2.7 Cayman had a note of 'slight oil leak' at a recent MOT. It was annoying, in part simply because I hadn't noticed it as I haven't used the car much. So I jacked it up and had a look. Firstly, the oil filter housing wasn't screwed all the way home which explained some of the leak. But there was also a noticeably oily pipe in the top of the engine bay. Here's a photo viewed from underneath. When viewed from above it seems to be this pipe. For reference, this is stamped with part number "987 107 064 01" and a brief google search suggests that it may be part of the AOS. However the oil filler cap can be removed easily with the engine running which suggests that the AOS isn't failing. Having tightened up the oil filter the oil level is still dropping slightly (a recent 350-mile trip caused one bar drop on the dashboard gauge) so I presume that the problem is still there. Has anyone any experience with this? Is this pipe a regular candidate for causing problems? Or is it likely to be something else? All advice welcomed, thanks. (I posted this on boxa.net yesterday but no one there has come up with an answer, hence this post.) Link to comment Share on other sites More sharing options...
