Lotus Elan

Oil Pressure tube and Mouse holes.

PostPost by: vincereynard » Mon Jul 24, 2017 9:54 pm

I'm slowly getting there with the rebuild.

One oil leak source was a tiny nick / crack in the oil pressure plastic pipe. Which then split in two upon applying a bit of pressure. Wouldn't that have made a nice mess?

What is the pipe specifications? Anyone know where I can get some?

Presumably I'll have to get the gauge out of the dash to change the tube - that looks fun.

Another problem is the state of the footwell seals , specifically where the column / handbrake pass through. The gap around the column is big enough to allow the entry of small rodents! (Or presumably large spyders.) Perhaps this was sold to the PO as an early form of air con.

Are these column seals unobtainable?

The seals and grommets should be available from Sue Miller or others.

The tubing should be available through Sue Miller or Miles Wilkins. You will also need new olives for both ends unless they are already furnished. An alternative is AN-3 braided stainless hydraulic hose covered with heat shrink vinyl and AN hose ends and adapters. Also available through your local Lotus specialists. You may be able to access the gauge fitting from behind the dash.

The column seal may be available and In theory the hole should be central but the vagaries of elan bodies can lead to needing something bespoke.
It's easily enough made a piece of 4mm rubber sheet. I used a piece of 15mm copper pipe to cut the hole and provide space for the cover countersinks.
To fit you'll have to loosen the column or slit the seal depending on how keen you feel!

Interesting routing you have going on there Vince. Don't know if yours is finalised, but on my Sprint the HT leads are 180 degrees from yours and point towards 8 o'clock.

Also my heater pipe is the footwell side of the fuel pump, not next to the block.

Just my twopenneth

Hi,
The hole where the steering column fitd through the bulkhead uses a now obsolete Triumph spitfire bracket/grommet assembly. What you have looks a bit of a home made job. Go onto the Rimmer Bros website and take a look.

cheers
Mark

When I rebuilt an early S4 to me ages to find a good one, thats how I know..

Good point about the 'plate' - a specialist dismantled will probably be the best source.
Try 'spitfiregraveyard' - he's very helpful.

I got my oil pipe from SJ Sportscars. As already mentioned, your dizzy seems way out in position.

Thanks for the replies chaps.

Sue Miller a braided hose for the gauge so I'll probably go with that. It's ?40+ (!) but not much more in the overall scheme of things.

She can also supply a bulkhead grommet so I'll see what it is like and maybe make my own if necessary. (Or another to make it double sealed.)

The heater pipe is too short to go to the other side of the pump and also interferes with the input pipe.

That how the dizzy was fitted when I got the car, so it would come as no surprise if it is in the wrong place. (Rather expected in fact!)

P.S. Upon reflection the distributor cannot be turned 180 as the dizzy / coil leads (red/black) would be too short. So it must have been set up like that. Not that it matters as long as the plug leads are correctly numbered.

I phoned round a few Triumph breakers and managed to get an ex Vitesse steering column seal.

So long as the dizzy leads are not fouling the underneath of the carbs. On my Sprint I run NGK resistance leads which have a much thicker outer layer and they would be interfering with the front carb, if they we prientated like yours.

There's not a lot of room down there, given the amount of plumbing, plus a steering column.

I've just had that heater hose perish where it's been rubbing the steering column clamp in the footwell.

There's always something !!

You don't have to use AN hose ends on your braided line and then adapters. Goodridge has proper ends to make up a proper replacement hose. I've used their products for over 25 years.

p.s. I would rotate the distributor & cap 90 degrees so as not to put a strain on the leads...
