Can AOS leak oil?

[sasha055]

Some more information

Car is 2000 base Boxster, 80K miles, runs perfect, no signs of AOS failure, I can pull the oil cap really easy and it runs a little rougher with the oil cap off

Thanks

the oil filler tube assembly is actually 3 pieces - the tube that bolts to the block, the main tube between this and the bulkhead, and the bulkhead fitting. i am assuming you only replaced the main tube in the middle?

two things - when i replaced mine i still had oil weeping at the join between the main tube and the piece that bolts to the block. also, the piece that bolts to the block can also fail, especially if you get tugging on it during the replacement of the other pieces.

Thanks,
I indeed replaced only the main one.
I'll check the other two.

Is there a write-up on how to access/change the other two?

Thanks

It's ugly for the first hose and how you get to it is through this write up: Pelican Technical Article: Boxster Coolant Tank Replacement - 986 / 987

So you might want to consider doing the coolant tank while your at it...if its old.

Advise is to remove the clam shell as it will give you more room to work around if your going to dig in deep. When you replaced the main tube did you remember to install the O-ring back on the end of it?
