Thanks, I think they are all lined.
After some races the car looks like it's been on a loose rally so needs a mega clean down. I do this and add a drop of oil.
I feel like a steam engine driver...

That oil smear then attracts dust and dirt which will contaminate the joint.
I've seen so many cars at the hills with red rust joints, dry as a bone etc.

The WD40 at least leaves a thin coating but I thought it was slightly abrasive?
Probably me just worrying too much....

With the Lola all done for the 2018 season I'm busy on the old 911 keeping it up to scratch and the Lola is all covered over.

I have had a few thoughts about it (oddly not including selling it), but as the car is, it is just so nice, but needs an FT200 gearbox!

Anyway, thoughts go to the festive season and one of my Xmas sketches.

May I wish you all a Happy Christmas, and above all a very health New Year for 2018!
Graham.

Seems to have been a very long hibernation!
Have been doing a lot of work on my first hill climb car, my old 911 and messing with an old 1950 Frence motorcycle that drives me mad...

Car is all checked over and nearly ready to race.
The first practice day is March 31 at Loton park, good day to clear things up and get back to the race weekend routines.

Have been given a permission for a new set of slicks!
This would have been the 5th year for the current set, but I think they are past their best.



Going to try an A92 compound on the front, A15 on the back.
Previous set were A15 all round.
The A92 is softer so good for front end grip, esp in the wet.


Carbs need a tune up but other than that ready for 2018!

There are 2 new cars with fast drivers coming to the class this year, and Nigel, my class mate for years says he is jacking it in, so I'm not sure this year will be mine, but time will tell with my demon tyres.
One new comer has a hard running Saker with 400 bhp and likes to go fast, and the driver is 10 years older than even me!
Other car is Nick in his turbocharged Jaguare V6 engined Lotus Esprit who will do a full season this time.
He was really fast even on road tyres....

There has always been a slow leak in the one rear wheel but last year it was getting worse.
This was the tyre or the wheel, and I suspected the wheel..


Put 15 psi in the offending wheel. Dabbed soapy water on the obvious places and then on the outer rim surface to be met with a very fine stream of bubbles and the discovery of a 20mm crack in the rim.

I was worried that these 1970's mag alloy rims had a pin hole that was progressing and I was right.
For now, the rim is scrap. (though I might have a Plan B)

When I first built he car I had huge width rims on it as the chassis came to me with them on, 10" wide fronts and 14" wide rears. Looked good but restricted the turning circle such that getting off Prescott at the top was nearly impossible.
With the new Blue body came the narrower wheels, 7.5" Fr and 10" rear.

I kept the 'big' rims as a set and today massaged those rims from the front for the rear to substitute for the leaky rear as a pair.

Bit of careful drilling and such like and all it well, the old wheels are the same size/off-set as the current rims, so everything lines up.

I obviously checked for leaks and they are air tight.

So, every cloud has a silver lining and I saved the cost of the new slicks today avoiding a set of rims for the rear @ 1000.

Of course, the rims on the rear are still 1970's magnesium, so the search goes on for a set like the have for the fronts.

Where would you get wheels like yours from?

Indeed, Dymags mostly have all gone back into the melting pot long ago.
The current fronts are ATS centres (cast alum) with MB Wheels' spun rims and BBS inside spun rims.

They themselves are hyper rare it seems, so much so I think I have the world's only pair..
No point looking for another set, so it would mean a visit to MB Wheels or Image wheels to replicate geometrically the dymags..
Cost is 816 for the pair.

This means they will have to wait a bit.

The re-fettled rims from yesterday's frantic recovery to get them to fit all seem ok, they have held 15 psi for 24 hours, so presuming I can get through the snow we are promised I can get to BMTR for the new tyres.

Need to 'time' my approach to The Boss for the MB wheels.

Err....
x 100 for the right Brownie Points and I'm in with a chance, or just sell my old 1950 French motorcycle.

With rac cars there is always a last minute glitch!

I contacted Ian Jemison in York to repair the leaky Dymag and it is on its way there (slowly) using DPD.
60 + 35 in postage seems a good deal.
Wife happy.

Fuelled and started the engine from dry yesterday, and after a splutter it ran on all 6.
Thought I would warm it up and check the flow rates on each choke as it was not quite a clean as usual late last year.
One throttle was down on flow, 7 were giving '5' and the other remaining on 4. Could not get the '4' up to '5' so suspected a leak....

With it running I gave the manifold/head gasket are a little whetting of carb cleaner spray and the note changed.
Repeated 3 times, note change every time with the spray in one spot.
A leak!

This engine uses a phenolic heat spacer between the carb manifold and the hot cylinder head, a paper gasket each side to seal things.
One is breaking down.
This has happened before, 3 years ago when several gaskets failed due to them breaking down with fuel contamination.

I always use Shell V Power 97 ron which I think has ethanol and maybe this is why they fail (?).
So, just ordered some gasket paper for the job and will make some new ones.
None are available in the UK and to get spares from PMO in the USA you have to FAX them!

Things always come in sets for me, brakes on the 911 and the Lol at the same time, air leaks on the Lola carbs and wheel at the same time..

I have 4 weeks to fix things, so easy.

When new they look like these. Material is paper impregnated with a graphite-like coating.

No response from the USa supplier, little response from the UK specialists bar one, so have decided to make my own gaskets, all 12 of them.

Today I pulled the carbs off.
The gaskets had indeed started to break down, all 12 of them, so all now removed and all mating surfaces clean.

The plastic heat spacers are not really flat enough to simply re fit using Blue Hylomar, so waiting on the gasket material to arrive.

Everyone I've contacted to ask if they can make me 12 gaskets have failed to respond...except one who wants to discuss things first, not a good sign.
So, making by own.
I hope the paper arrives tomorrow so I can get the job done and the engine tuned using my air meter and trusty Colour Tune. (remember them?)

Here are today's gaskets showing rather clearly the degeneration of the gasket material from the side that was leaking air.

If you have trouble getting gasket paper contact me and I can send you some. I have loads of sections cut from making outer gaskets for Imp engines fitted with wills rings. The inner section is waste and although I use them for making other gaskets I have loads which I can't bear to throw away. Approx 350mm x 80/100mm.

Thank you Pete.
The paper was ordered 2 days ago, so should be here tomorrow.
If it goes pear shaped, I'll let you know.
Graham.
