Was at the Biggar Vintage Rally on Sunday and noticed that I seemed to need more correction to the steering than I normally expect. I could see that there wasn't play in the box so crawled underneath and jacked up each side in turn to check for play in the track rod ends. Found none but when flexing the NS front wheel noticed that there was a little relative movement between the wheel and the drum. Yes, it needed the spinner tightened up better.

That's scary! I am sure you had thoughts about what might have happened. _________________ a car stops being fun when it becomes an investment |

It did worry me when driving. In fact the additional half turn of the spinner still required a fair whack with the soft hammer so I think there was a fair amount of resistance to further slackening.

Peter. What do you think caused the spinner to undo?
I thought the way they are tightened (with left and right hand threads) prevented it from happening...

I probably just didn't tighten it up enough the last time I had the wheel off. They don't tend to slacken off for the reason you suggest.

Cleaned one of mine ready for Tatton Park tomorrow, popped out to get some fuel, all ready to go home, started the car and no oil pressure. It sometimes takes a bit of time to build up (oil pump is in the top of the engine, so it has a lot to suck) but it just wasn't having it this time. So I swapped all the stuff into the other car, started the car briefly to turn it around to push it back into the shed, oil pressure comes up just like normal.
There's obviously something wrong, though, and I can't risk taking it somewhere and finding that it goes for good. Pity, really, as this is the last show I've got booked for this year. _________________ 1976 Vauxhall HP Firenza, 1976 Vauxhall Sportshatch (x2), 1986 Audi coupe quattro, 2000 Audi TT |

If the oil goes to the gauge it may need bleeding due to some air in the pipe
Disconnect or loosen the pipe at the back of the gauge and turn the engine over on the starter only, until steady flow of oil and then reconnect/tighten the pipe to the gauge. |

I can’t see how air in an oil gauge line would affect the reading? |

It's not a problem that I've encountered myself but the theory is that they need to be bled like hydraulic brakes need to be bled because the air is compressible while the oil isn't. |

My TC may be old technology but I encountered a situation that means if I drain the oil then the pump need to be primed. While there is a plug for the purpose when oil may be used, if the pump has been disturbed (new gears etc.) it has to be packed with petroleum jelly to get sufficient suction to get the oil to where it needs to go.
I didn't believe it at first ....but it is common practice if you don't want to 'run' the bearings. |

In a straight pipe, there can’t be any pressure difference between either end whether it contains air or fluid or both, oil gauge pipes are so narrow that even if completely full of air, the pipe volume compared to whole oil system is so small that any air would be instantly compressed with negligible pressure loss.There is far more air in higher parts of the engine like tappers that needs to be shifted when the engine has started.
Unlike brake hydraulics, where the volume of fluid movement is limited by the master cylinder swept volume, the oil pump keeps pumping oil, raising the pressure until the relief valve kicks in. |

Not posted for ages!
Had a starting issue with the Singer last week, took a hunch that it was the fuel pump failing due to the diaphragm rotting with the newer fuels.
Bought a rebuild kit and sorted it today. Starts very well indeed so it may have been on its way out.
Gearbox sump leak to sort next.
