so I have a late model 302 with a reverse rotation water pump and serpentine belt. I read somewhere that if the water pump begins leaking out of the weep hole, it means it is going bad and time to replace it. Is that true?

If so, anyone know how long I have before it totally goes out? I have barely driven this thing since I rebuilt the engine..guess that is what I get for buying a cheap rebuilt water pump...and I am just not in the mood to replace the water pump right now and would like to get some miles out of it.

Yup, replacement time. It might go like that for years. It might totally fail tomorrow. No way to know.

If you try to run it longer, make sure the fan does not wiggle front to back at the ends of the blades. That means the bearings are also shot. If they let go completely, a fan can mate with the hood or other parts. Not fun.

Change it. It is an easy fix and not nearly as expensive as the engine. I had one do the same thing and it went from a little to alot in a hurry. I was in Europe at the time and had to wait. Glad it arrived when it did.

thanks guys...wonder why it failed, hope it isn't because I am running an early model timing cover with a late model pump...guess we will find out next time around. I hate changing these things out and i don't know why, they are easy to do. Don't think I am going to gamble in this 100+ degree weather we are having.

hey Pete...just curious what size tires are you running and do you have a lift in the rear, or drop in the front? I just put some 215/45/17's on and they are a really low profile compared to the 235/55/17's I have in the back. Don't think mine is as exaggerated of a lean to the front as yours, but I was just curious as to what you have done.

Yeah, sounds like new pump time.
You mentioned running an early cover with a late pump. How early and how late? Just curoius, in doing so you have a potential for mismatch.
Early timing cover example-

Later cover for a reverse rotation pump-

It's possible to bolt the the incorrect pump on if you ignore the two extra bolt holes. If you do then you will have overheating problems later if not immediately.
I'm not saying you did this but since you are going to change your pump anyway, it would be an excellent time to check.

I have 195/60/15 in the front and 235/60/15 in the back. The rear rims have less offset than is ideal but I never measured it. I would like a wider rim with the outer portion to sit as these do. The rear leaf springs have a 4" lift built into the arch. The bubble of the rear tire sidewall is even with the outer side of the body. Here is a better view of the rear tires. As far as I know, the front springs are stock.

I can't remember what year the timing cover is for, but for some reason, I want to say it looked different then that. I know it has a dip stick location in it, so I know it is for an earlier 302 though. I thought I had all of the bolt holes covered, but I will definately do some double checking. Thanks.

Ah, i see. Your stance is because of the 4" lift. I only had 2, which I guess is allowing me to get the larger tires under it, but not so much in the front. Originally I had some 14" wheels that stuck out like yours, but every time I hit a bump, they would rub, real bad, so I decided to go with 17"'s.

Don't buy the cheapo parts store pumps. Get a quality aluminum pump (Milodon, Edelbrock) and you won't have to worry about it again.
