As these guys have said chamber lube is a big no no…

I've had several Diana's through the years that had damaged piston seals from the factory and another often overlooked problem with them is the rather cheesy breach seal set up on them.

The way the breach is angled and the main reason for barrel droop on a lot of Diana's 

Often they need to be shimmed for a proper seal. I've heard of some using dental floss but I use steel shim material and make my own. The seal should sit at 8 to 10 thousands above the the breach. 

It has done wonders for me in the past especially on the 34s.

Just my 2 cents …
