Title: It's official ...
Post by: Julian on April 18, 2015, 11:12:43 AM
... I admit it, I'm a complete Muppet who shouldn't be allowed near engines in the future.

Yesterday, I took the vacuum and lift pumps off the Disco to try and find out why the level of rust inhibitor had increased on that side of the engine.  I think I may have found the problem ... the end cover of the vacuum pump is riveted on and it was that that appeared to be leaking.  Rather than drill all the rivets and muck about with the pump internals, I reset the rivets using the vice jaws and a lump of steel rod.  The gap between body and cover closed noticeably squeezing oil out.  Only time will tell if it's cured the leak, allowing most of the rust inhibitor to lubricate the engine.

Feeling quite smug I jumped in the car and set off for a near by town.  300 yards down the road the engine all but died.  It would only do about half revs in 2nd gear.  Yet another of my heroic failures!

This morning I discovered the problem ... I'd got the suction and discharge pipes on the lift pump round the wrong way!  So the LP was trying to suck fuel out of the filter and pump it back to the tank!

I'm amazed it ran at all.

you could do one of those videos where god told you how to increase your MPG to 1000 MPG by buying my carefully researched book. only 5.99 plus a free  gift.

Dam, I never thought of that before disclosing the secret!

Sounds about as far as I got when running only on the fuel in the filter :)

Horrible feeling that finding somewhere safe to pull over - quickly!

You'd better get the mrs to to put L and R on all your shoes to prevent further errors, while she's at it put back and front in y'pants.

I know exactly what you mean ... I drove into some bushes on a roundabout, but managed to keep the engine running for a short while and then when there was a break in the traffic limped home at about 10 mph.

If she did that I'd be looking for the steering wheel every time I looked down and saw LR.

And I don't wear any, that way I can never get them in a twist.

That is a common problem with the Britpart vacuum pumps. I have repaired 3 of them now by drilling out the rivets and using nuts and bolts instead.

Didn't know that ... so my summation was right ... that's a first!

I don't know if it was Britpart ... are the originals fixed differently?

Is there a gasket under the cover?

I'll keep an eye on it and if it's still leaking do as you've done.

They all look the same but you can tell if its Britpart when it starts leaking  ;D
There is a rubber gasket under the cover. It is safe to take the cover off. Nothing will spring out when you do.

Great info, thanks.  If it starts leaking again I'll try that.  Just worried that side of the chassis might rust now.

Hmm ... having read all of that thread, it seems that there shouldn't really be any oil at that end of the pump ... it appear it indicates leakage past the piston.

Need to keep a close eye on it me thinks.

At least it'll match the rest of the chassis and body work.

Did you see the use of that special LR word "common problem"

Cast your minds back to a few years ago, what make of car pulled most of the stranded cars from Chugs field.

I know my C250 was worse than useless.

Maybe the LR lot should wave as we leave the lawnrover bashers behind next time  ;)

Don't let those nasty bullies get to you ... just ignore them and they'll go away.

I did ignore them for a few months, but I came back and they were still here.

I just have to remind myself that I was once a lawnrover basher, then I saw the light and got one.

Now let me see if I remember correctly.

What was the vehicle that Jules spent most of a recent BBB underneath repairing? ???

Yeah that's it, a Lawnroamer.
