Re: Points box Russell wrote: Why's my points box full of oil? Because the front oil seal is leaking..... It may just be the crank case pressurisation issue rather than a terminal seal.

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.
