Mk4 Golf Injector Replacement

[dom]

The injector seats are threaded so would need to be twisted off. Ideally you need a huge hex bit to get them out.

  I ended up having to shave a 21mm wheel nut in order to get them off. I tried every (shoop wise) to get one without any luck. I think ebay have them tho.

Okay cool, i'll do that, so do you think it is the injector seats that are causing the over pressurising? my problem is that even if i can fix this problem, I still have a misfire that is being caused by something to do with the injectors.

thanks for all the help! it's much appreciated.

A leaking injector seat would cause a fuel leak from the injector area

right okay, i can't see any fuel leaks anywhere around the injector, it only leaks through the electrical connector :/

Here are some photos, In this photo: http://i1372.photobucket.com/albums/ag332/jamieisafish/Mobile%20Uploads/image_zps9dd30ce2.jpg
you can just about see the fuel in the electrical connector.

This photo isn't great but again it's of cylinder 4 where the misfire is: http://i1372.photobucket.com/albums/ag332/jamieisafish/Mobile%20Uploads/image_zps886d854a.jpg
Cylinder 1 also has fuel in the connector as well. The injectors aren't leaking from anywhere else

Did you replace the little rubber 'o' rings on the top and bottom of the injectors?

[jamiesgolf]

Yep the replacement injector came with new o rings so yeah I replaced them.
