swiftstu Posted July 13, 2019 Share Posted July 13, 2019 (edited) Hi all, Can any club members offer any advice on what may be causing a a leak from the pipe in the attached photos. It’s quite a bad one, but I can’t work out what the pipe is. It looks like it’s just press fitted? I can’t find any tech Info searching the forums, but ahead of taking things off I’d like to order any parts / gaskets I might need. Thank you in advance! https://1drv.ms/u/s!Aq0iXwZ_BEW7lFsd1ndXaJWQ6kxq https://1drv.ms/u/s!Aq0iXwZ_BEW7lF19zQzm8e_9VSCC Edited July 13, 2019 by swiftstu (see edit history) Quote Link to comment Share on other sites More sharing options...
swiftstu Posted July 13, 2019 Author Share Posted July 13, 2019 Ok so there’s nothing I can do to attach images at the moment they all fail. Apologies. Quote Link to comment Share on other sites More sharing options...
Tyson Posted July 13, 2019 Share Posted July 13, 2019 Ok so there’s nothing I can do to attach images at the moment they all fail. Apologies. It is most likely the image file size is too big try uploading to an image hosting website then copying the img link. Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted July 13, 2019 Share Posted July 13, 2019 The pipe that is leaking is more than likely from one of the two rubber o-rings that hold the water neck to the bypass tube. To fix this you will need to drain the coolant from your car. Remove the distributor, then you can access the waterneck. Waterneck is only held on with two m6 bolts. Once those are off you will need to remove the bypass tube. Depending on how corroded it is, this could be as easy as pulling it out, or getting a set of molegrips on it and trying to rotate/pull until it comes free. Assembly will be the reverse of this, using your new O-rings. Be sure to grease the o-rings slightly on install, as if they have no grease they can tear on install, causing a leak.

I can’t find any kits of those O rings on ‘tinternet. Do you know if generic O rings would do? I have one of those massive selection boxes.. Thanks for the responses!!
