I’m glad the Darracq has only oil and water to leak as it seems I have plugged the former only to uncork the latter.
This morning being the second Sunday of the month was the local club’s coffee morning and as it was white with frost the perfect time for taking an open car for a spin. Apart from a touch of exposure the trip to Warragul went well with no oil leaks although in the past it needed something more than 12 km to really show.

The real problem appeared on arrival back home and on inspection the radiator had sprung another leak.  This is the third leak the first being when the fan pedestal broke and pitched the fan into the radiator, fixed with epoxy chewing gum, the second on the same day as the first but from natural causes fixed with stop leak in a bottle and now this one, it may be time for a new core. Not sure how to finance this one as I’ve already sold the children.

The Darracq has always leaked copious amounts of oil from the rear main, particularly after a good run usually depositing a 6 to 8 inch puddle on someone’s pristine driveway.
So today as I’ve already put one car off the road and the weather is a bit shitty I might as well disable another.
Darracq has Paris and London on the badge so the London part would explain the multitude of bolts holding on the sump and still not managing to stop the oil weeping out. Otherwise the sump came off easily and everything looks ok. The “slinger” is in good nick however I don’t know what the clearance is supposed to be between it and the sump/crankcase so will have to do a bit of research. Something that I could not see with the naked eye but shows in the photo is a bit of maybe gasket material in the groove between the slinger and the flywheel flange. Whatever it is didn’t work.
After consulting Andrew I might try a mod where I will drill a hole in the oil pan at the back of where the slinger bears diagonally into the sump to act as a drain.
