Hey guys I need a little bit of expert advice. My new to me M20L has developed a leak. Under pressure the water comes from between the lever springs. Do you have any advice on how to fix this? Also where the best place to find a new spring would be?

I am guessing that to repair the leak you need to replace the piston seals.

So others know what this is, it's a vintage La Cimbali one group commercial lever machine. Here's a thread on H-B about one:

La Cimbali M20L - First Pull

Thanks for the attached link! The group looks exactly the same as on my 75' LaCimbali M15. Although I'm still in the restoration process, it kinda sounds like some water is leaking past the upper piston seal(s). I'll take a look at mine in the morning just to confirm, but I think that's it.

+1 on drgary's post. After looking at mine, I definitely think water is slipping past the piston seals.
