 piston rings I'm changing the piston rings on my visa engine as well as trying to eliminate the usual oil leaks around the cilinders.
Could any expert give me some advice?
Thank you.

Re: piston rings Hi Vitor
I wouldn't call myself an expert, but first off, what are you hoping to gain from doing the ring change?

Re: piston rings Stop oil consumption, mainly

Re: piston rings So, are the pistons and bores ok?

Re: piston rings It's not me who's doing the job. It´s a friend who is kind of 2cv mechanics expert. He showed me the parts and said everything looked OK (until now  ) but the piston rings showed some signs of wear, which I/he guess(es) is normal after 160.000 kms... aggravated by the fact that the engine has been running on LPG for maybe 100.000 kms.

Re: piston rings That sounds plausible.  I would not have thought LPG would affect the rings, more likely the valves.

Re: piston rings As far as I could see the valves don't look worn out, but they weren't disassembled yet...
Anyway this is the 2nd engine (the 1st one was a 602) I've been using running on LPG, and I'm not so sure that gas is a bad option.
Besides, it is supposed to be not so pollutant as gasoline...
My aim was to use an electric kit for the 2cv (like they do in Paris) but I couldn't find it yet.

Re: piston rings An electric 2CV sounds cool.  I was running my Bedouin on LPG for a while. It wasn't set up correctly, and I eventually had running problems with the engine. Back on petrol now, but I hope to go back to LPG but with an injection system soon. Regarding piston rings, I guess you can change them and try it.

Re: piston rings How are the cylinder bores? (Visa engines had a Nikasil coating).
