constant steam from pressure release.
hi,
after receiving my mallard back from hornby for a second time this month it is still not running smoothly. however I just noticed that while trying to heat up, there is a constant stream of steam coming out of the pressure release valve rather than short bursts. also while running it seems to not have enough pressure to move properly.
I remember seeing a help guide on the old website about this but with all that gone I can't find info on it.
any help would be appreciated as this used to be a great loco but now it's just frustrating.
here is a video for reference. https://youtu.be/pq1v0IB_FcM

sorry forgot to reply. I took the loco apart like you said and checked the inside of the safety valve. it appeared to be all clean in there but since putting it back, it seems to be running much better.
thanks for the help.
