E92 oil filler cap

[foresterlad]

Last month there was a thread on M torque(RIP) which dealt with a problem of blow by through the oil filler cap. This seemed to be cured by a service modification which consisted of a modified cap
My dealer is unaware of this. Has anyone knowledge of this or re-calls the M torque thread
Thanks

It was asked last week, i looked into it, and the part is infact the e46 m3 filler cap.

It'll be in one of their technical service bulletins they haven't got round to reading yet.
