I'm getting ready to put my 1.7 back together and am wondering what you people do to insure that the push rod tubes don't leak. From what I saw taking it apart this is where most of my leaks came from. Is it possible? or were the tubes designed by the British? thanks.

In the VW world they now have spring loaded ones that always have tension on them - I have used 2 sets and no leaks 2 years later. About $100 for 8

About $100 for 8 Maybe for a T1 but that won't work in a T4. My biggest trick is I use a 1" flap sander and give the bores a quick once over and I also debur any sharp edges before the final cleaning and install of the tubes. I use the dow 55 Oring lube slight twist as I install. Once done be very careful installing the retaining spring and Bob's yer uncle. |
