Radium King's suggestion is very interesting. It is not a regular catch can.We have already discussed that idea and concluded it was a good idea but space is so limited,it is difficult to execute well.
The part Radium King links is quite different to say a JAZ catch can. It is much smaller.
This may solve the installation/space issue .
It does not solve the problem of the diaphragm splitting? However,if the AOS no longer gets 'swamped' that may prevent the diaphragm getting stretched and soaked in oil.
So this may by a vital part of solving this problem.
Of course it is not Smog-Legal but what Smog Tech would see/know?
There is no need to empty the Grimspeed because it is not a catch can it is an AOS.It is less than $300.
The big question is -"Could you use a Grimspeed AOS to completely replace the Porsche part?"
