Is the weep hole on a TR6 water pump supposed to face down or up?

Thanks Doc.

I'm the guy that would have ejected right over the area I just bombed - lol.

Wasn't sure if the weep hole was potentially used for lubricating the shaft or something.

It's there to evac the pump when the seal fails. And to alert ya you ain't spent enuff money yet. :smirk:

Most early auto water pumps used the cast iron surface of the impellor as one of the sealing surfaces. These were prone to sporadic small leaks. The weep hole is there to allow any coolant to drip (weep) out before it gets to the bearings. Modern seals use a ceramic or sintered iron surface which has virtually stopped that non-sense. Original Chrysler slant six pumps had a small trough under the weep hole to divert any drippings away from the fan belt that ran right under the pump.

Antifreeze, while a good freeze preventer, does not do much for metal to metal lubrication.

One sure way to wipe out cams, lifters and bearings is for antifreeze to leak into the oil.
