LT1 water pumps and weep holes, what gives?
I have had 3-4 water pumps on my 95, they all end up leaking from the weep hole. Why does this happen, and what is the purpose of the weep hole accept to leak on the opti!!! ? These don't last very long...

Every mechanical water pump I've ever seen has a weep hole. It's to give an early warning of failure. If there's any other reason for it, I've never heard it.

I wouldn't have anything else on an LTx engine. Where the hell you been, Tom?

The other purpose of the weep hole is to allow the leaking coolant to drain out before it gets to the ball bearing.
Old mechanical fuel pumps had weep holes.
If the oil seal was leaking, this allowed the oil from the crankcase to drain before it got into the fuel -- usually, you needed a diaphragm leak too for this to happen.
Or, if the fuel diaphragm was leaking, it allowed the fuel to drain before it got into the crankcase.
Sometimes the leak was so severe, it didn't work too well.

This last one was a Carter made by Federal Mogal, and I thought it woudl alst longer, but I think it is only 2 years old. This went on to replace the new one I had put on that leaked as soon as it was put on.
This one seemed good, adn I didn't notice any leaks, but when doing head/cam swap, the current pump looked like it had dried residue around the weep hole, so figured it is leaking, and should replace while easy to get to.
What is an acceptable "small amount" for one to leak?
How do you attach a hose to it, it is only a very small hole? What if it was just pluged?
I am not convinced on the E-pump for a daily street driver, plus I would have to send my Camber-brace in to have converted too. If it goes out again, maybe I will try one.

Get a vacium hose fitting and epoxy it in the hole then connect a piece of vacium hose to it and route it down pass the Opti. Next time it leaks it wont take out the Opti.
