 Points box
Why's my points box full of oil?

 Re: Points box
I assume there's an oil seal on the end of the cam behind the advance weights? Nothing too involved or owt?

 Re: Points box
No seal on the camshaft, only an oil return scroll like that on the gearbox input shaft... Crankcase vacuum test? ken

 Re: Points box
No seal Russell but a oil sling cut in to the cam shaft, keeping the oil out. Sound the crankcase ventilation is kaput (oil breather)

 Re: Points box
I still haven't done one of those. It's had a new breather this week since the one I rebuilt had a hole in it. I'll stick a new set of points in it and mop it and see what happens.
Thanks guys.

 Re: Points box
There's a seal on the crank that can dribble into the point box. I'd check the easy stuff first though. Gasket on the reniflard, crank case pressurisation..
I have a new (pattern Cassis) reniflard that's been put together incorrectly; it's twisted and hits the fan housing. You're welcome to it if you want to cut it apart and fix it.

 Re: Points box
At least I know where to come if I need a spare...
Thanks 2-fiddy, I'm going to re-flap this one at some point.
