Montblanc Meisterstück 149 Making "hissing" Sound When Being Filled

[Siguchi]

Hi everyone,

I noticed that when I'm filling my Montblanc 149 (either with water when cleaning it or with ink), the pen makes a hissing sound (like if the air is escaping from somewhere) when I'm retracting the piston (i.e., drawing ink into the pen). Is this normal behavior and do you experience the same thing with your pens?

On a maybe related note, I noticed that sometimes I get ink on my fingers when touching the collar like as if the ink is leaking from the space between the collar of the section and the barrel. I sent the pen for repair two weeks ago (and it was quickly repaired) so I wonder how they couldn't notice if there was a leaking problem when inspecting it (if there was one).

It is not notmal. Souls like air leaking in. It could be the barrel I'd tou have one of the two piece barrels from after about 1985. You can see a seam just after the ink window. It could also be a leak due to the piston seal not completely sealing. Could be rough edges or a flaw in the barrel surface causing this.

 

Of the pen was serviced by MB I would get it looked at again. This should have been noticed.

+1 on getting it back to them.

I agree with Zaddick,likely a crack in the lower barrel or the seal not holding a vacuum.
