Gear Selector Seal leak
 

Hi All,
I have a 2002 Boxster S, 6 speed manual. I've noticed a small oil leak coming from the gearbox selector shaft (selector seal I think). Oil then drips from the vertical bar (on the right hand side of the engine when viewed from the back) that moves when changing gear.
It's not a major leak, a few drops each time I park over night.

I took it to a dealership, and they are talking 10 hours labour to remove and refit the gearbox, the cost of gearbox parts kit and suggest that while they have the gearbox off that they fit a new clutch (with clutch clutch kit costs) and possibly new flywheel if needed too. All up over $6k Aussie.

My questions are: Do I need to worry about the gearbox leak, and if so are the dealership giving me the right info? Can the seal be changed withouth stripping the gearbox? Should I have the clutch changed at the same time if not, and should I have a new RMS fitted then too?

Sorry for the questions list, but I''m a Porsche newbie and it's my first experience with the dealership.
Thanks in advance.

Firstly welcome, its good to have another Aussie on here.

Get yourself a good workshop manual. I purchased the Bentley one from the USA & it was here 4 days later. Cost about $130 AUD and you will save that the first time you do any work on the vehicle.

Find an independent workshop who works on Porsche's and get a fault analysis & quote from them.

If it is not a major leak, can you live with it till you need to replace the clutch?

Thanks Pinarelloman, have ordered the Bentley Service Manual and should be here in a few weeks. Also booked my car in at a local Porsche specialist, so will update once i know what's happening.

If you are referring to where the selector shaft enters the gera box on the tail housing, I’m afraid you will find the dealer (while over priced) is correct: The gear box has to be removed and the entire tail housing must be replaced.

The shaft passes thru a bronze bushing, which has worn out of round, causing the leak (not uncommon). The problem is that the bushing is not replaceable due to the fact that it is pressed into the housing blind, and then machined in place to create the opening for the shaft to pass thru. Replacing the outer seal will only stop the leak temporarily; it will come back unless the bushing is replaced. As no one outside the OEM gearbox supplier has the correct tooling to do this, the tail housing must be replaced, which means pulling and disassembling the gearbox……
