Who said it was going to be easy?

This will form a problem:

One solution Region. Admittedly it was a bit of a faff, but ohh the noise (I have not yet measured noise which may be an issue given your track use)

[rj]

Can't do that due to noise restrictions. 95dB at drive by and the meter is at the entrance of the long straight, just where I hit max RPM.

[Paul Mason]

Ah, I was 96 or 98 I think (IIRC) with the airbox on at 5k rpm....so my help is no help

[rj]

Paul,

Is the underside of your bonnet polished?

[Paul Mason]

Yes, I did it when I first got the car about 18 months ago. Mainly spattered now though

[rj]

And where's that backplate from? (And the filter?)

[Paul Mason]

Back plate was from Jenvey (second attempt which still requires a bit of a modification to not foul the chassis leg after my first flat backplate purchase was miles off) filter direct from Pipercross, though they have a different name on the internet. I'll see if I can find the invoice

Thanks,

That looks very tidy. I'm not much of a polisher. Every five years or so it get a rub with Scotchbrite.

Could the oil connection be moved to the front?

[rj]

It looks like the tank is dual-walled so that the space between the to walls is used for deaeration. Regardsless that's what I'm going to try. I will move it far enough to make the hose connector clear the air filter, which I also have to replace as the big and long I had on the car has too big a major external diameter and will foul with the side of the tank.  Please cross your fingers.

[Wrightpayne]

Would an easyclean in the footwell be an option?

Or perhaps a belltank :-p

Ian

[rj]

Neither of those Ian.

The belltank won't accept my clutch release bearing and would require some thinkering and they are hard to find.  I don't like the easyclean tank. With a little welding I will like the Brise tank.

[rj]

This is better:

Tight but doable. I will probably offset the tank 1/4-1/2" to the left (in the driving direction) to make sure everything clear. there'll be a lot of hoses (or is it a can of worms given the nature of a Caterham?) behind the radiator, but I think it'll be OK en the end. The new connection is an elbow to throw the oil against the wall as the original inlet did, so no worries there.
