Oil Leak

Hi all,

I have an oil leak on my GTI near the gearbox and would like to identify the source. It is not coming from above.





Is this likely to be the driveshaft flange seal ?

Thanks for your help !

Yes , it seems to be the problem , but not a pain to do.

When ordering , do no forget the green part  , and be careful to choose the correct flange seal .


Cheers.

Can it be done without removing the gearbox ?

For sure.

Drain the gearbox ,  

Just remove the alen bolts , and you'll be able to change the flange seal ,
There is a clips a bit boring to remove/install
But doable .

The flange has a big spring behind it and you to to make some sort of tool to hold it in or you will never get the circlip off and if you did the flange would fly off and possibly damage something or you…

Guide here to changing the flange seal, it can be done on the car but access is a little tight.

You will need to drain the gearbox oil so a good time to upgrade the oil to fully synthetic.

Here's how I dod it on the car using a Slightly Modded ford steering wheel lock tool, and a 3 finger pulley remover.

Thanks,

Is there anywhere you can buy the removal tool ?

 

Have a look at this thread for some home made tools.

The 2 or 3 I have done have a F-off big spring behind them that sends the cup whizzing past your head… the PITA is getting them back on which needs some sort of threaded bar contraption

Finally starting to plan to do this job.

Does anybody know the correct part number for the seal ? There seem to be a few options. I will change the gearbox oil but should anything else be done at the same time?

My car is a standard 1983 1.8 GTI

Many Thanks !
