  • Leakless Pump Follow Up

    I am so sick and tired of water pumps that leak! Just about to fire up an engine that I rebuilt myself (just rings, lap in valves adjust all clearances, rebuilt dizzy, carb and water pump). I filled with 50/50 yesterday morning and saw a very slow drip at the pump. But from every thing I can tell it seems to be coming from the pressed in bushing and the pump body. The drip only was about 1/3 cup in around 24 hours, and it comes right down the face of the casting where the bushing comes through. No leak on the shaft to pack nut, and if it was coming out around the threads of the pack nut I would think it would drip off the end of the pack nut and not travel along the threads to the casting face.

    Do you think I can either add a bead of RTV as a fillet along where I think this is leaking? Or is anyone a proponent of the leak stop additives to the coolant?
    I have already decided that whether I can afford it or not I am going to get one of the sealed bearing pumps for my Roadster, but was going to leave this Town Sedan with the one I rebuilt.

    Is there a crack in housing ?

      No crack. The pump casting on this car (had sat in a barn for 30 years) was cracked at the front of the pump, so I bought a body from Bert's and it appeared to be fine. Bought the double lip seal bushing from Bert's also and pressed that in. I did not check closely to see if the casting was scored where the bushing goes in. My thought is that maybe there was a scored line in the casting from removing an old bushing and this might be causing the issue???

        I'm not sure why your pump is still leaking without inspecting it, but which ever route you take stay away from the Technician in a can temporary fix or RTV. It would be best to fix it right instead of having an issue on the road, plus antifreeze makes a mess when it leaks.

        FYI
        The best leakless on the market are the extreme pumps by Rupert.

                My car came with a "leakless" pump and so far no leaks. How does one distinguish who supplied the pump ?

                  NO ONE seems to put their "BRAND" name on them. I once saw a rebuilt water pump, with a sticker inside the water part of it, that said, "WARRANTY IS VOIDED IF THIS STICKER IS REMOVED"! (I REALLY saw it, with my own eyes! I don't ever lie, except in bed---LOL)

                    I did some reading about the James Rupert pumps and I think he does about as much as can be done with that approach. I think they should be durable enough to justify the price. I agree, they are the best on the market.
                    I take a completely different approach and use a modern ceramic seal. They are pricey to make and there is a fair bit of work involved so they would be too expensive to market. Like the Rupert pump, they look completely original when fitted. I have made one for each of my Model As and won't have to touch a water pump again in my lifetime.

                      Frustrating Water Pump Rebuild
                      by Roadster Rich
                      This should be easy. I posted about two weeks ago about the bushing in the rear of the water pump. Replies were to use the dual lip seal bushing. I got info from Steve at Bert's about which bushing that was and I ordered two. I have a new shaft, impeller, front bearing race, and the cups, felts and washers for the front bearing. I also had a very good condition "leakless" pack nut....

                      by Roadster Rich
                      I have a "leakless" pump on my roadster that I assembled about 25 years ago. I have a pump to rebuild for my barn find town sedan. I ordered a leakless kit with the stainless shaft for the TS and had to get a new core from Berts, as the original had a bad crack. The question is whether the pressed in brass bushing at the rear of the pump is any different than an original bushing? I used...

                      Leakless water pump
                      by plyfor
                      Is the rear brass bushing with the seal supposed to be lubed?
                      Not sure what pump prior owner installed.It looks stock from exterior and shaft doesn't move laterally. Any way to tell without removing pump to see if it has modern components?

                      by Roadster Rich
                      Trying to fix a leaking water pump and I am puzzled. I made the mistake of taking apart the current pump and then putting all the parts I have accumulated together. Wouldn't be so bad except that the newest leakless pack nut has the seal taken out of the pack nut (me bad) and now I dont know which way it goes.

                      I hope I have loaded the pictures properly. I need to know which side of...

                      What Maintenance on Leakless Water Pumps?
                      by 29er
                      Since I've got to install a new head gasket and will have the water pump off anyway, is there any maintenance to be done on leakless water pumps? This water pump has about 5,000 miles on it and has functioned without problems. As far as I know, all the bearings are sealed, and other than cleaning it and adding a new gasket there's not much to do, right? How many miles have you guys gotten out of leakless...

                      Original and leakless water pump info
                      by Tom Wesenberg
                      When I rebuilt my water pump in the 90's I rebuilt it completely original, and it never leaked a drop in over 10 years. When I did the block and radiator flush with vinegar I had a real mess after the vinegar removed the grease from the packing rings. I then installed the new rear bushing from Snyder's with the double lip seal. The seal will help ensure the coolant and grease stay separated. I loosen...

                      Ruppert "Leakless" Extreme Duty waterpump leaking
                      by AL in NY
                      I bought a Ruppert leakless extreme duty waterpump in 2010 thinking it would outlast me. Well after eight years(warranted for 5) and 15.000 miles it's leaking. Has anyone had a Ruppert pump fail? I'm going to call them tomorrow and see if they will repair it (on my nickel) or if I have to buy another pump.

                      Attached are pictures of the water pump that was on my car when I purchased it. Is this an aftermarket pump? if so, will a rebuild kit work on this. I kind of like the idea of having a grease reservoir handy.

                      Water Pump Rebuilding, Packing Nut Question
                      by Kevin in NJ
                      Working on my water pump. While it has the leakless bushing, I am putting in the packing too.
                      The kit comes with an Aluminum packing nut. I have several old new pot metal type packing nuts.
                      Should I use the pot metal ones or is there a reason not to use them?

                      Thanks.
