Peugeot 406 oil cap blowing off

Car: Peugeot 406
Variant: HDi
Model Year: 2002
Categories: Leaks & Noises
The oil cap keeps blowing off and and dip-stick rises up by about 2"... someone told me it was a problem with the crank-shaft breather pipe but I'm not sure where that is. My mechanic doesn't know either(!) Any suggestions? We've lost 3 oil caps so far!
