Vanguard creed leak

[sl2ai]

if you have 2 (and 1 that works) cant you just swap the parts over till you narrow down what the issue is?

 

[funder]

1 is a v1 and the other is a v2 .

If the leak is on a V2 Creed follow @Big_jim advice and also look to see if your schrader valve is loose or damaged.

If the leak is on the V1 look at the valve body and check the poppet, I assume it's a plastic poppet?

 

[funder]

Yes it has a plastic poppit.
What part is the valve body

 

[foot]

The valve body is the internal part the poppet sits in, in your case the valve body is black.
If you have a spare poppet swap it over. If you haven't put up a wanted thread as see if someone has one.
