Dear Forum members. I am proud member of silver Tourer 2003, Executive with 240.000km on the clock. My first post was here asking if anyone could give me an opinion on two Diesel Tourers when i was buying but than after seeing 9 Accords (6X Diesel, 2X 2.0 and 1X 2.4) I have decided to take the last one. It was the least expensive, taken with care with history and most important the engine run the smoothest and much better than all others. Since i am the owner now for 1 month i have done some maintenance by myself, changing oil and all the filters. I have also cleaned very rusty rear pistons at the rear brakes. OEM service mechanic has changed oil in gearbox and changed brake oil completely. They have also changed upper front right arm and both lower ball joints on lower arms. Not to mention this is the last time spending too much money on OEM Honda mechanic... One thing to mention is that I have installed LPG from highest rank called Prins. I get 12.4 L LPG / 100 km combined and I tested my car before conversion and it was 9.6 L Fuel / 100 km. So that means now i have 10Eur/100 km which i think is very good. Prins has each injectors and each waxing / cooling per valve. I think this was the most important for me. I am absolutely aware i have to adjust valve clearance more often now, I was told every 20.000km. Now here comes the part I am concerned> Local mechanic told me today that his experiences so far with LPG gas conversions on Japanese cars are not so positive. He guaranteed me I will have to change all the valves around 150.000 km on LPG. He have seen many used Hondas on LPG without any compression measured on cylinders which valves were worn out completely because of LPG explosion. His statement was that Hondas have very thin valves which can be worn out quickly. Are here on forum any LPG converted Honda members with more than 150.000 km on the clock while on LPG? On the other hand I have spotted less power on LPG when pulling from lower revs. I know time will show but what do you guys think have i made mistake? I have spotted much surface corrosion from below the car when car was lifted. Is this normal? How can I remove this?
