[Spridgets] Sucking oil through PCV valve

[stargazer1 at cox.net (David Ambrose)]

We have a desmogged '70 Midget. It has the earlier carbs without the 
vacuum intakes for crankcase ventilation and has been fitted with a PCV 
valve. It's taken to pulling oil into the carbs via the PCV valve. The 
valve itself seems OK, but I can't think of any other reason for the 
problem. We've already been through the sealed vs. vented oil filler 
cap, and have a vented cap on the car.

Any ideas appreciated. I don't particularly want to order another PCV 
valve for no good reason.

Thanks,
Dave Ambrose
