Oh, I see. That is unfortunate...

 Well, hopefully you get well soon...

Next year no Holland event. But I guess we will come to UK, maybe...

right friking oil surge.....

well measured up and no room by abs unit to get a natural fall for oil return....had a thought that penny washer may be holding oil up as well,,,, forcing through hole then draining back slowly and then forcing through some more and taking held up oil with it...theres just no room under the bonnet for a decent sized can.....
its gotta breath else gonna blow the sump sealant or summit in engine....

gonna strip oil filler neck off tomoz and stand and look at it and scratch my head and wait for an epiphany to occurr.... :violent1: bolt a catch can on roof would work....

Have you considered a vitron flap valve? You could easily DIY one to sit where the filler extension pipe bolts on.

Im seriously considering a check valve there....closes on reverse flow...so if lifted by surge shuts...plus i stared at engine today and done a little drawing of a catch tank i can fabricate out of dairy tube at work which will sit along my strut brace to allow a fall to filler neck...so if it does surge can then drain back.
Its gotta breathe as dont wanna blow out my new sump sealant lol....which is my concern with a check valve as exiting a right hander at combe on throttle surges closes valve and blow by pressure blows sump seal or summit else in engine...

I might look at doing this myself tbh. Though i'd be inclined to go real basic and sandwich a vitron membrane with stainless mesh above it at the joint. Drill out the centre of the membrane 5mm or so and segment it into four so it looked similar to a gun sight reticle. The mesh above will stop it opening up during blow-by and gravity will assist any oil that does bypass to open the flaps and facilitate a rapid drain.
