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. |

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

Stop oil consumption, mainly |

So, are the pistons and bores ok? |

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. |

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

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. |

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. |

How are the cylinder bores? (Visa engines had a Nikasil coating). |

But I assume it costs more than you want to spend on that . https://www.mehariclub.com/fr/eden-electrique/ |
