Posted January 12, 200421 yr comment_63882 Just trying to brainstorm here,I get a new msa clutch master cylinder, it's been installed for about 2 years. The black res. cap has never really fit well, and will just slide out if you pull up on it, without any twisting at all.Looks like a design defect.I would like to make it seal better.......has anyone solved this problem?Thanks in advanced,Dog Link to comment https://www.classiczcars.com/forums/topic/9696-help-with-a-msa-clutch-master-cyl/ Share on other sites More sharing options...
January 12, 200421 yr comment_63903 I've had a couple that had loose fitting caps. Try a different diameter O-ring on the cap and it should tighten up the fit considerably. I had one that had an O-ring that was so thin in diameter you could barely notice any difference with or without the O-ring.
