what are these valves for

I think you forgot to add the picture

Are they under the rear bumper ? If so they are the valves for pressurising the hydrolastic suspension . It has a mix of alcohol and other bits in it under very high pressure and requires a hydro pump to increase the pressure . Do a search on hydro pump and you'll get some designs for pumps .

errrr....Which valves?

1977 Leyland Mini LS - Project LS-T

which ones?

the ones that keep the air in your tyres, and let you put more in, or the ones in the engine that go down and up to let petrol/air in the motor, and let exhaust gases out?

they change the note in a trumpet - or a french horn. You can replacements from any good music stores

yes i am on the music site.
pic on now

Woohoo , I win

Yes , Hydro valves for pressurising and depressurising the suspension . Don't try and pump it up with air , much too high a pressure for it , around 250-300 psi (from memory , anyone know for sure ?) .

_________________

Leyland Black book says with new displacers, pressurise to 350psi early and 400 psi late models, for 1/2 hr. Then let down to pressures shown on chart in General Data for different models.
Helpfully, this essential? hydro information was omitted from General Data- in my 1976 book anyhow.

Typical Leyland....

It's in the Scientific Publications #64 I think. Will search and find...

OK here we go-

Early 263psi
Late 282 psi

No dates or car numbers given for Oz made cars.

Don't you just adjust to prefered finger height..rather than a Number Specifiec by the Leyland


more of a question...why is one exhaust rusty and the other black with oil...is that a fakey

nice spot!
looks like a fakey to me

I reakon its a fakey

Yes that's what you do, height is more important than exact pressure.
I just use 3 fingers between the 165/70-10 tyre and the front wheel arch.

I was only using the pressure as an indication of it being very high and way above a compressor (and not air ...) .

_________________

whatever height you want to set it to, i would still do this bit. it is the pressure test at higher than operating pressure to see if you have any leaks. although, i am guessing that this is not explicit in the leyland book, and it does not tell you how much the pressure is allowed to drop in the 1/2 hour to pass the test

It was a pleasure ausmini. I'll miss all you misfits and reprobates

That test is only if you fit NEW disdplacers, must be to flex the internals or something. NOT for normal pumpup of s/h ones it says.
