I feel your pain. This was a multi week ordeal for me. I went thought the metal pipe URO crap and then went to brass. I also learned about filing down the square corner. I posted a pic of that I believe. I took a razor saw to the timing cover as you mentioned. Having that slight extra seal is not worth the pain. Besides, where I live, it hardly ever gets bad weather so there no dirty water or slush being flung into that area. When I took the belt cover off, everything looked practically brand new.

The final frustration for me was the length of the straight brass pipe. Another user used a shorter piece but I couldn't get that to work. I had to get a 1/2" longer piece before I could complete the job. I took off the housing at least 3 times.

I'm glad to say that several months and thousands of miles later, everything is holding up wonderfully.

Bought one of the metal replacement bleeder fittings from e-bay. When received found it was too small to make a tight seal. Cannot remember how much smaller than original, but enough to not seal. anyway I scratched my head for awhile, and came up with a solution. Used small piece of 1/4" shrink tubing over the metal nipple to compensate. Greased it before installing, and all is well. Cannot break the metal one installing/removing the timing cover

Interesting idea, but I'm wondering if heat shrink tubing will provide a watertight seal when the joint is under pressure and it heats up in a hot day? You'll have to let us know how it goes.

The heat shrink tubing is still providing a watertight seal after 2 months. I know it sounds like a hokey fix, but it worked.

Also want to mention there is not much pressure at this junction due to the small size of the hose.
Hope this helps someone with this issue. Was a quick and easy solution.

Thanks for letting us know the longer-term result, sounds like a great fix for this sub-standard URO part, hats off to you!
