Wondering if I’ve finally seated the bleed valve correctly.
Popping up tab on bleed valve reveals a burbling sound which goes away with tab down. System still holds pressure and does not leak out overflow valve.
Despite having an .04 cap I think that is now the culprit.
Off to dealer to grab new cap. Fingers crossed!
Many thanks for all of the great suggestions.

With things working correctly you should be able to pump the pressure up to around 14 PSI and it should hold the pressure.
If you do a search on the forum someone has probably listed the spec for pressure but 14 PSI is in the ballpark
