Hi all
I have a couple of leaks on my Sprint, its up on jacks so I've noticed a puddle of water on the floor its not a huge amount but enough to be concerned
I am almost sure its coming from here (this is a previous pic the engine is back in the car, but that orifice is obscured)
Does anyone know what might cause this?

The second minor leak is gearbox oil and it seems to coming from here

If I take OD sump off to change the gasket does it dump all the oil

That's a failing water pump seal. If the car hasn't been run for a while it may 'bed' itself back in again, but you'll probably have to refurb the pump.

You'll lose a little oil taking the filter plate off the overdrive, but not all of it by any means.

Hi Steve, Yes my 1850 wasn't used much over last winter and it was dribbling a bit from the cast-in slot. That was quite a surprise as I use EWC ( no water content ). As Alun says, run it for a couple of days and it may stop; mine did.
Keep in touch on this,
Cheers for now,
Tony.

Thanks Alun and Tony

I'm going to leave the water pump alone for now but at least I now know what to address if it continues or gets worse
The OD leak I'm going to have a bash at over the next week

Hi all,
I have the same problem with my 1850, I`ve just run the engine after a lengthy lay up during which I replaced the Pump housing top cover with
a `new` recon unit from Rimmer (std 6 vane), with gasket thickness selected as per specs in thew manual.
Water drips out of the slot under the pump when stationary and at a considerably faster rate when the engine is running & system is under pressure.
Judging by the amount I don`t think I`m going to be lucky enough for it to bed back in.
Which seal has failed? do I need to buy the whole refurb kit and does the pump drive shaft need to come out to fix this leak?
Thanks,
Ian

I`ve just spotted on the Rimmer Website a water pump water seal pt no 148322 which lists under stag parts but not Dolly for some reason
I guess this is the culprit and I just need to get the impeller off....?

I had a bit of a mare with mine, but most of it was of my own making
Once I realized that it wasn’t going to bed back in, I bit the bullet and decided to take it out and rebuild/Refurb

I got the water pump repair kit for Paddocks (JPS128) taking the pump out was no drama and doing the rebuild was surprisingly OK apart from I broke the brass cage!! I didn't seat it properly in the press when pushing the impeller off, I used the press because I have one, but I don’t think it would be too bad to take the Impeller off without the use of a press, I’m sure there’s a few folk on here that have.

I had a mare trying to get the old bush out, but got round that by a piece of luck, I was lent a M16 taper tap by Mig Wielder (Tony) and although I couldn’t quite use the method Tony suggested, the thread perfectly fitted my slide hammer, so I just screwed in the hammer and popped it out 😊

I managed to get the impellor faced, I found a friendly machine shop they are not a motor factors operation but they had a lathe so I walked up there with the dog and they did it while I waited, he wouldn't take any money no matter how hard I tried
With the impeller faced, the pump back together and the bush fitted into the block the pump went back in OK, I had other issues after that but that was more Sprint inlet manifold to Sprint head related
