Hi there,
That has been out for some time.
Next bulletin will be a revised service procedure with Anerobic sealer, which should be out in Jan.
The seals noted there are made now out of Viton, however, did NOT totally eliminate the condition of leaks.
Now, from the factory, the 04s starting in mid Jan will have the revised procedure and the anerobic sealer.
Allthebest, c4c5
