A Lotus day

Recommended Posts

So I thought I might do the brake callipers too, but I couldn't get the pipe of, so I cut it, thought I might go braided hoses to replace the solid bit on the hub and the flexible bit to the chassis.

But I couldn't get that off either, I was working on the theory that if I went far enough I would find something solid and start from there, a good theory, I just didn't expect to end up back at the master cylinder. So I'll just bit the bullet and get some braided hoses made to to right from the master cylinder to the callipers. (suppose that's what you expect after 19 years on English roads)

Anyway, because I have the radiator out being re-cored I thought it wise to check other cooling components, that nice "L" shape of tubing between the radiator and the chassis, it looked a bit shabby and I wanted to check the rubber hoses anyway. After I cleaned up this nice piece of aluminium pipe it was much easier to see the pitting and pin holes in it! To which I reflected well I'm glad I didn't find out about that half way across the Nullarbor!

Some days are good, some days are bad, I'm still thinking about today.

Roger,

At least you're still thinking.

That's a good sign.

I've had my 88MY Turbo for 7 years now and I'm at last feeling happy.

Frantically searching around for a bit of wood to touch!

You have to look at it as a project without a project plan as it never totally achieves sign off.

Keep walking till your hat floats.

Kind regards

Alan

When I had the rad out on mine I found similar problems, I needed the car back on the road, no option. Red Hermatite coated the aluminium tube than covered in a rubber sheet with hose clips to hold it in place. You could see the holes by where the red pushes through into the pipe.

I must replace that one day.

Good find Roger.

After mechanically restoring my car, I have found that the only trouble I get is with the parts I have not replaced ie the head, rear bearings etc. It seems like it is just a matter of time...

i spent the day taking the rear passenger caliper off and stripping it down and rebuilding it, the handbrake plunger lever had stuck and i had no choice to sort it out, took a few hours to do, and all i have to do is bleed it in the morning , its as good as new now. put the piston in all the way and turned it so its locked to the push piston inside.

Speaking of callipers, I had the rear ones off today. When I bought the car, the guy gave me a stack of invoices one of which is for reconditioning the rear callipers, OK 3 years ago, but they're rubbish, boots don't split and fall off in three years, both inlet fitting and bleed nipple were just about frozen, again if they were freed up 3 years ago they wouldn't be in that state now.

Just plain bad workmanship.

I coat my brake nuts and bleed nipples in clear Waxoil now, that way it hopefully stops water ingress to the thread and makes the next repair so much easier.

I agree that boys shouldn't fail that quickly, maybe the person couldn't get the kit and simply stripped cleaned, greased them and put them back without new parts (bodge, but gets the calliper working)

Mechanical numptie question here - but at around 5 years old the main agent said the coolant pipe that goes through the chassis on Lottie had 'rusted' and he'd cut the end bit off.

13 years on, I'm wondering what's to stop the pipe through the chassis getting leaky with age - or is that a dumb question?

"Rusted"?

Rotted maybe, but as it's aluminium you don't usually use the term rusted.

The main thing is with aluminium, it's salts aren't water soluble, unlike iron slats which dissolve and so the metal erodes. Aluminium is more reactive than iron, but as the salts don't wash away it becomes protected by a layer of oxidised salts, so with the right anti-freeze it should remain good almost indefinitely. Ali pipes on the outside of the chassis aren't so lucky, things tend to hit and brush against them,so the payer gets worn away, a new layer forms, but that is more metal gone eventually leading to a water leak.

Inside the chassis the pipes should be quite safe, as long as the gear change mechanism and other things don't keek rubbing against them.

Where the ends of the aluminium pipes are covered by the rubber hose seems to be a huge weak point where the oxidation eats deep into the alloy....

It aint good and is worse on the pipes that have never been touched for their entire life....

Its a real problem and a real pain in the ass for it....!!!

I spent a fortune replacing my radiator for an aluminium one about 3 years ago, along with 2 big kenlowe fans. (much lighter, skinnier, yet more overall airflow than the original Ford Escort Popular plus fans that were on it before).

Since then, I try to avoid going under the front as much as possible in case I find something else equally expensive that needs replacing!

I only usually drive around the Isle of Man, so I should never be further than 32 miles away from my pal who has a trailer <_<

If it aint broke, don't fix it, in this case. I'll look forward to driving past Stewie when his pipes go!

Hey, nothing wrong with my pipework!

Actually, there's a lack of backpressure and inability to pee over garden walls these days, but the doctor said that's just age and not to worry. And the diagnostic check for THAT would be more pleasant using Freescan...
