[RICE RACING]

This is VERY COMMON on cars not running oil metering pump but even on cars fitted with them.

I have seen this mostly on Bridge Ported cars, both Weber fed and also fuel injected. The problem is that bad that the sump smell like petrol, and always raises in level.

This happens on well cut side seals too, its mostly to do with the excess overlap period and other factors seen in these engines.
