Pictures of IP Weep Hole?

[ZWilson07]

Im pretty certain for sure that my IP is leaking out of the weep hole but I want to actually see how bad before just forking out the money for one. Ive tried over and over to find a picture that actually shows where it is but search results and google never really helped me much.

Ive asked before and had a few give me descriptions of where to look while the trucks running and all that, but just curious if anyone has a picture to go with it that is very specific. That would help me greatly as the picture is worth 1000 words.

Ive tried to find it over and over but its usually kind of dark under the hood, even with a light in my hand and trying to feel around and look with the truck running and that fan right next to me and 3 v belts spinning around, isn't the most comfortable or easiest thing for me to do yet.

Thanks

The weep hole is right behind the pump flange. Not all pumps have it. Older pumps had a bronze bushing instead of a needle bearing on the input shaft, and those did not have a weep hole. You don't need a picture, honest. Just put your finger down there. It will be wet if it is leaking.

Yes, what he said. I have had them leak there and while standing on the drivers siide of the truck I could plainly see the drip coming from the pump flange.

Here is a pic of the bottom of the pump, weep hole is circled.

Thats a really nice picture as asked for. In that pic you can clearly see the two other locations of a possible leak. On the bottom left side is the plunger cap. It has an 0-ring there. On the right side is the actual plunger shaft. That has a seal keeping it from leaking. Its not very often they leak but a possibility anyway. The inlet end of the pump has an o-ring seal too as does the distributation end of the pump. Mine leaked there many years ago but was an easy fix by trained hands... Not mine thats for sure...
Looking at the drive end you will see the o-ring that keeps the engine oil from leaking out of the gear drive. Also see the drive flange notched area. That fits into the drive gear so you can not mess up the gear timing like some gasser distributaters can be installed backwards.

Any other differences between newer/older pumps? The guy that helped me recently install my pump pointed out to me that my pump going in was an old one. Is there any downside to these?

Thanks for the quick response and helpful pictures.

Any certain date or year when they switched to newer pumps?

Mine is the original 1990 one so I dont know if that would be considered the older one or newer style?

Also like rockbender asked, any pros or cons to each one if replacing it?

Thanks

Interested in knowing how the bushings compare to the needle bearings
