Bad luck! Hope to see more of this car and your work on it.

I had something similar occur on the Ford 100E sidevalve engine in my Dellow, some years ago.
Although the cam driven gear shaft was fine[so the distributor continued to function...which was not fine, pretty much?]....the bottom of that gear driven shaft had a peg, which drove the oil pump!
This peg snapped off, severing the oil pump drive.

Luckily I was not far from home [ less than a 1/4 mile]....I just happened to glance at the oil pressure gauge, to see zero pressure.
So I did the quickest handbrake turn the thing has ever done, and chugged back home solely on what was in the bearings, and getting splashed around, oil-wise.

A replacement drive gear was fitted [which involved engine removal, as I couldn't get the sump off..it was 'blinded' in one small spot by the chassis tube.
Now I am not sure whether the shaft was a weakness waiting to break..or whether it broke due to the oil pump being more 'difficult' to drive?
The oil pump itself wasn't original in design.
Someone in the distant past had modified a twin lobe type oil pump [possibly from a Renault?]....to no doubt ''up' the oil pressure, when the thing was supercharged [in the 1980's]...Maybe the 'effort needed to drive the thing was beyond the capabilities of the drive, I know not.
It now has a brand new oil pump of original spec [ A Chinese-made item, or thereabouts, the sorting of which is entirely another tale]....a gear driven pump...

The oil system had been modified to include a full flow{?} externally mounted oil filter [Aquaplane valve cover]....with a take-off to lubricate the supercharger, when it was fitted [it no longer has one] The output oil passage has been modified [ a blanking tube] to direct oil into the filter first, before being sent to the centre cam bearing, as a normal Ford engine did.

My Cannon trials car, which had a variety of small engines fitted, had fitted a huge amber light on the 'dash'....[ a bit like those huge 50's trailer wing lights?]...with quite a brightbulb, fitted tot eh oil pressure switches.....so if pressure dropped, a huge orange light pierced the gloom of my foggy brain.
I'm thinking of doing likewise on the Dellow.....as well as the gauge....Better than a teeny weeny glow bulb?

At least with the Talbot design (or should that read Hillman Minx design?) if the oil pump drive fails it also stops the distributor, so a useful self-preservation feature!

I have finally got the engine apart to confirm that the drive-gear at the top of the oil-pump drive has stripped four teeth. Frustratingly the oil pump that the Sunbeam Talbot Club can supply is completely different. The Hillman Owners' Club don't hold spares and are unwilling to help a non-member anyway, so I need to find another source for parts. Speedy Spares recently closed down, does anyone know what happened to their stocks?

I suppose these people are known to you?

Thanks, Ray; yes, they are looking to see what they may have.

I found these people. No idea of cost though.

Could be expensive for a one - off. If you had a small batch made perhaps you could sell the others and recoup some of the outlay.?

[mikeC]

Thanks, Ray. That's an option I may have to consider.

Well, eventually we are back on the road! It took four oil pumps, all supposedly correct for the car, but all different in detail, to make up one good pump. The idler gear had seized on the original, and one of the other pumps was missing that gear, which suggests there may be a fundamental problem there. A friend who specialises in racing Formula Vee cars confirmed that it is a known problem with air-cooled VWs, so he has engineered a similar mod for my pump - a machined groove in the spindle and cross-drilling of the gear itself.

We now have 50psi hot compared with around 20-25psi before, and hopefully no more problems with the pump! After nearly a year off the road, a 70-mile round trip sees it back in action.

Excellent news Mike. I goes to show it's not just what you know but who you know that counts.

[Rootes75]

Yes, very good news and a great bit of advice.

Lovely to see her back on the road.
