Anyone have any opinions on whether this Tap and Drill Technique would work on the plastic oe t-valve if I were to grind off the socket? I have ordered a new upper hose set already, but then I came across this so was really just interested! Thanks

 

What's wrong with yours? Not a good idea when you should be able to pick up a BMW PN 17111712788 to use unless your T threads are bad. There's also a risk of cracking a brittle T when taping.

The vertical side piece of the socket has a tiny crack from over tightening. Today I put some epoxy on the sides and around the socket, unfortunately, after a test run around the block I was getting a small coolant stream out of the microscopic crack. All threads are solid and streamline on both bleeder screw and T-connector.

FYI, sockets have been traditionally referred to as female due to having plugs inserted into them.

Glad to know new hose assembly headed your way. The male bleeder plugs have an o-ring and once it needs replacing some folks over torque them causing the cracks. Always a good idea to have a spare plug, they can be hard to find if dropped or o-ring slips off.

That is brilliant. I think I'll try to do that this weekend.

 

The Bleeder screw isn't the issue.. the socket is cracked so no matter what position the screw is set to I still have a small stream of coolant flow...

I think when the new upper hose arrives I will put the Brass Bleeder screw and not mess with it. I'll bleed by raising the reservoir tank. Thought?

 

Hi Jomandm
Do you remember what size tap u used?
Thanks
Micko

 

The drill size for 1/4"npt is 7/16". Be careful how far in that you run the tap. They are tapered and if you run it in too deep it won't get tight. I know there is a joke here somewhere. D*

Ok Jomandm here is my effort.
Works well so far
