Hey Marvin.
This is almost certainly swarf in the Ally head. Jeremy Welch is aware
of a batch of heads with this problem and a fellow club member
encountered it earlier this year. Give Jeremy a call to get the remedy
method first-hand from the man.
Sorry about the mandatory disclaimers at the bottom, but I am in work
and felt this needed an immediate response.
