No worry all will be fine, the air cooled engine is a good boy, not really powerful but reliable. In your case there is not much weight to move.
I read that you had to clean your car several times after racing in the wet. I'm quite convinced you can manage to keep the breather away when cleaning but not when driving. Unless you have it in your pocket! Talking in the pocket, enough for now you have laurels waiting for you!
Have fun, be safe and win!!

Yes, makes you wonder:

Maybe the particles were finer than the filter - unlikely?

Does the oil circulate fully, is there a way it bypasses the filter?

Then where did the particles come from - external or internal source.

If internal what could it be - as you said little ends would seem most likely, in which case it's slightly less critical than crank bearings.

Did wonder if it could it be from the oil pump itself - does that have any brass surfaces? Or similarly distributor drive?

But I'm sure you've already been through these kinds of thoughts.

Even if it's something like crank bearing failure I imagine that given the length of hillclimbs you're unlikely to destroy the engine, more likely to end up with knocking sounds or no oil pressure than internal parts ending up external?
Then the break in the championship could give you time to rebuild it.

The filter being super clean did you check the drain pan first?

Yes, I drain the oil first, put it in a can for the tip, then unscrew the filter using a chain type grip to unscrew the can without puncturing it.
Once free of the engine oil pours out and the empty catch pan is used to catch that flow and the filter that I put in there quick as a flash.

The new filter goes on empty as it is near impossible to fill it on the bench.

The engine is cranked over until good pressure shows on the gauge before switching the ignition and further cranking to fire.

The pressure does not change during this procedure.

Here is the filter set-up, all Porsche 911 from the 993 engine.

Thank you g.

It is bad when you have a bit of time on your hands and a race car sitting in the garage...
As some will recall, I have been bugged by the gear change quality in the car for years, and when it works it is a surprise at 70 mph, so my intent wondered off to improving it.

The layout is in the diagram below, and the major inefficiency is in the 45 deg short link from UJ2 to UJ3.
1/2 the effort I put into a change is lost in that link, so the effort to select and change gear is quite high and contributes to the quality of the change, negatively.

Tried before but with far more determination was to make a much longer and 'straight' angle between UJ2 and the input shaft of the box right at the end of the car.

After some tedious fabrication and welding and such like against all odds I have managed to sneak the new link just under the one silencer but not hanging down under the belly of the car, vulnerable to attack should I go off-roading in the car (it has happened before...)

All done and painted and my right knee decided to tear a bit of ligament, so stopping all re-assembly!

So we have gone from all ready for the year to the car is not ready for the start.

I've had the knee thing before so some rest is called for and all will be fine.
The Members Practice Day at Loton Park will prove this effort one way or another.
Everything I've done is reversible, so I can go back to the last layout within an hour using a few spanners.

Got all the new parts back on the Lola today, shift feels a bit better, not the radical improvement I expected, but difficult to tell in the garage.

Driving will be the real test.

Next step will be a new gear lever that will give far more leverage but that needs a bit more work.

Still have my knee problem, so decided to 'motorise' the trailer, a mover for the axle and a bright new winch.
Could save further damage in the months to come.

I'm getting old!

Would it be possible to fit a 914 gear selector to the gearbox?
Apparently they fit early 911 boxes and would give you a forward facing selector to connect to but no idea how much the boxes have changed over time.

Hello Peter,
The 914 cars box is quite a different design, and some had a side shift which is a good thought, but the torque of the engine would kill it!

Hi
That's what I wasn't sure about - the 914 main casing was apparently a 901 (e.g. early 911) one, but with the forward facing shift.
I guessed they have evolved the 911 gearbox over the years to cope with the increasing power/torque.

Well it's intriguing looking back at all these different mechanical designs. It makes you think when you see all the different chassis that were used which was best

Might be called all part of the fun, but a few duff gearchanges in hill climbing and it is 'Hero' to Zero.

It is truly the only bug in the car, the chassis by McClurg's is perfect, engine good and strong, wish it revved to 7800 though, and it is very nice to have.
People occasionally offer money for it, but my immediate response is no, so I must still be in love!

A box that cannot be rushed, I have the same box in my ex hill climb 1973 911, can't rush that either, but with a well defined gear shifter and H pattern it is better.

All I can do is to try to improve it, hence this exercise.
I will find out if my demon tweek is good or simply another 'demon'

A swop of drivetrain to a modern Porsche Boxster would kill several birds with one big stone. That box has a cable shift and is very good and fast too.

To make things worse, I am lucky enough to have a Boxster so I know what it could be!
7800 red line, bags of torque, fuel injection, big clutch, but...
Not air cooled!

Luck ran out!
Found out last week I had forgotten to enter the Member's Practice Day....
Over subscribed, I had no chance to get in, so went to see who and what was there today.


Surprise was this car could be in my class this year, a Pilbeam MP42, HART engine and a very experienced driver.
Ran Loton hill today in 55 secs, my best is 56.
Also have a Metro 6R4 V6 turbo, a real one....

Might not get the Trophy this year. Time will tell.
