Disco 2 Alternator Vacuum Pump Oil Leak

A new oil feed hose (YKL100120) is not cheap at all - c.AUD 250 for genuine L/R, so, if necessary, I might look at taping over the current hose with self-fusing silicone tape as a remedy if it is the source of the leak? Has anyone ever tried that? Any comments?
My guess, without any evidence to base it on, is that unlikely to seal against the pressure and heat. Wouldn't it be possible to replace the flexi bit with fuel hose (no problem with temp and pressure, depending on the type) and use hose clamps? I had thought of replacing the drain hose on mine using fuel hose.

Just a thought.
 
Be interesting to put up a poll along the lines of how we all learned.
I like you am mostly self-taught. but was lucky to have friends and neighbours with knowledge.
Did NOT come down from my Dad, as apparently happened to quite a few. And moved too far away from my Grandpas, who were both engineers, at an early age.
But the net has really made things a lot easier for all of us.:):):)

Yes, the net has made things easier - forums, YouTube videos, step-by-step guides and online manuals. On the other hand, vehicles have got more complicated with a lot more electronics, requiring specialist tools and knowledge in many cases.

Have to confess I think cars could be fixed by almost anyone with a bit of mechanical knowledge until fuel injection came on the scene.
And that only happened to me in about 1991 when I bought one of the first BMW 528is. ;)
This kind of coincided with the moment at which Haynes manuals started telling people not to even try stuff, rather than warning them stuff might be a bit difficult!:(
And also when you needed expensive kit to check your car would pass the emissions test. :(
So in some ways it is a wonder I am still playing with cars, especially ones as complex as Land Rovers!
Do love the way we have peeps on here who are so "up" in the electronics, as that is my massive weakness, though I am learning slowly.
And I've bought a Foxwell!
I always ask here first before looking elsewhere on the net.;):)
 
14.6V measured with engine running and no observable oil leaks. So, all good! The AUD75 alternator tested good (stator and rotor windings, slip rings, brushes and rectifier) before installation, so, I'm very happy with that purchase - reckon it'll last many years (I might need to change brushes in 3 - 4 years).

If someone can explain how to replace the slip rings I can fix my old alternator!

Gave this some thought, there is such a thing as an "olive removing tool" that plumbers can use. Not that I have ANY idea how slip rings are fitted. Can you not experiment on your dead alternator? Careful action with a junior hacksaw cutting at an angle, for instance?
Or if they are soldered on, a bit of heat from a soldering iron to loosen them?

Looking forward to your finding out!
 
Running for several days now with alternator/vacuum pump - steady 14.6V from the alternator and no oil observed - all good. The old unit was covered in oil, and so was the driver's side front axle area, steering box area, and the bottom of the battery box and intercooler hose. I cleaned all the oil off before I changed the alternator/vacuum pump and it is still nice and dry. I suspect the oil was being sprayed out at the banjo bolt on the vacuum pump; two new crush washers seem to have fixed the oil leak problem in that area of the engine (there is of course an oil leak somewhere else I have to fix at some stage!).

The mechanical seal, metal and NBR, between the alternator and the vacuum pump (Toyota part number 29341-64130 / Nippon Denso part number 081103-0080) - found it at local Toyota dealer (said he's never seen/sold one) here in Melbourne, Victoria, Australia - AUD41.40! - he can get it from the Sydney warehouse. Bit pricey for what it is!? Seen it on alibaba.com as well: https://www.alibaba.com/product-detail/29341-64130-Oil-Seal-17-30_1600119164193.html.
