drysump pump on xflow lubricating my driveway

[janolesen]

The car 1968 Lotus Seven with a 145hp 1600cc dry sumped xflow.

Oil is dripping after blats, it comes from the 5 port dry sump pump, apparently it comes where the metal tube(scavenges oil from the sump) is attached to the pump housing.

The metal tube feels loose but how do a tighten it? There is no nut and I cant see how it is fixed to the housing.

without pics, who knows.

Maybe its threaded, bonded, welded, fractured ???

[janolesen]

yes, a picture would be helpfull.

and here it is:


All the other ports are with threads and nuts, this one I don't get.

Looks like a push fit or crimp of some description...

I guess the only we to do anything, is to take it all apart to investigate.

It's a press fit but by the looks of things it's not a very sturdy housing it's pressed into. Side loads from the hosepipe and vibration have probably loosened it off. That corroded bit doesn't look too clever either. A better solution would be to have an aluminium pipe stub made up to suit on the lathe out of a bit of bar end, pushed in at a light push fit and then TIG welded into place round the top. The corroded bit could be ground out and welded back up at the same time.

At a pinch you could just remove the existing stub (heat the casing up with a propane torch) and loctite it back in with something like Loctite 638 high strength retainer.

BTW, I do hope there isn't as much silicone sealant inside your engine as there is outside it. It's meant to be applied lightly not trowelled on.

Alternatively, thoroughly degrease it externally then gob up around the joint with a nice, thick layer of chemical metal.

Clean with wire wool then with acetone, and doggie it up with epoxy. It's not under pressure so all it has to do is cover the hole, more or less.

Thanks for the replys.

I'll do the quickfix with expoy now to fix the pain.
Removing the pumt is a engine out operations, so I'll find find a more durable solution this winter when the engine is out anyway for maintanence.

Thanks
