We cleaned a 1500 Dolomite block off with a solvent prior to fitting a new gasket and must have left a residue of the solvent/thinners in the hole, as when the engine was run up to temperature the gasket blew at the edge of the mystery hole?

Original part number 141357 Did anyone find a supply for the correct 19mm bearing or a satisfactory way of overcoming the replacement 15mm item that seems to be on offer?

My car was a Mk1 2lt and what happened was a tooth had snapped off the pinion due to worn bearings allowing the pinion to move up and down and there wasn't room between the crown wheel and the casing. The tooth punched a similar sized hole to yours in the casing. 500 yards later the diff started making whining noises and I stopped. I traced the streak of oil back to its beginning and there was the piece of casing and the broken tooth laying in the road.

Years ago(too many if I'm honest) fairly sure it was an article in the Courier ,you basically remove the ash tray and its housing that is held in place by knob mountings either side (choke control and master light switch ) then make up a blank same shape as the ash tray but a bit bigger to carry the gauges.

Some cars have a line fuse to the rear lights that lives in the left corner of the glove box.

Try resetting the trip to zero and give it another go. I had a similar problem and it was just the tumblers had got stuck. This maybe useful https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=2ahUKEwia4vjDjo3mAhWP-aQKHa1-ATYQFjAAegQIARAC&url=http%3A%2F%2Fobswww.unige.ch%2F~wildif%2Fcars%2Fdocs%2FSmith-jaeger_speedo_repair.pdf&usg=AOvVaw33d-onw9QrtuVptkc8F_SJ

Im not climbing into a freezing loft to search 42 years worth of club mags but that's how I remember the club name being decided on.

There was possibly a small amount of oil laying in the cavity between the block and back plate pressure washing the engine has possibly pushed and amount of water into the cavity, as oil floats on water it has raised the oil up higher where it has now escaped . The oil must have come from somewhere so as Pete says it needs investigating.

My Marlin has been running around for over thirty years with a Scalextric motor magnet Araldited to the original sump plug.

Thanks for the links and pics all food for thought .
