We converted the mercedes a few years ago. We replaced a lot of the parts, unfortunately the engine died. The grease kit and fuel pump pay for the car itself. Will even throw in a few cubes of oil.

haha, I love that

Use Water-Injection on it....

That'll curre the loss of compression--IF that is the cause by Ring-Gumming...

Run WI for 50 to 100 miles, will remove the gums and restore compression fully!

My thoughts are:
If you have to modify the engine to make a fuel type work, you shouldn't be running that fuel.

Man that is a shame. I wish people would do conversions right the first time. I do more work on repairing peoples poorly built kits than ever before.

Yah, but Rudolph didn't design our engines

Our honorable members here who hate alternate fuel - Does this post imply engine using diesel will run forever? Any diesel engine will bite the dust at some time.

Only the ones sold on Ebay last forever

I am not against alternate fuels. Just saying that in an unmodified engine (water injection ) wvo will shorten the life of that engine. Can you drive 20,000 miles between oil changes? Yes, but engine life will be reduced.

That shouldn't be a hard and fast rule. The use of CNG on a standard gasoline engine is an excellent modification.

Gee, I've never seen any non veg oil dead MB diesels on CL before.

Here are three dead cars in two post from a quick search of CL.

People choose to pay attention to the facts that support their opinion. And don't always look at the whole picture.

But modifying a turbo or an injection pump, or injectors, or various other things to get horse power is okay. I've haven't modified my engine at all, I have stock injectors, and haven't touched the IP timing. I've modified the fuel system and added some heat. After 45k miles of VO use I'll take you on in a cold start challenge any day. My VO 240 fires right up, idles smoothly, doesn't smoke, and drives great. And my engine has 305k miles on it.

Now, I'll repeat what I alway say. If you do it right it will work fine for a long time. If you skimp and do a shotty job when tweaking the IP or turbo, or injectors, you're gonna pay for it. Same goes for VO. If you put together a subpar system your gonna pay for it down the road. People skimp and don't maintain their cars all the time. Not only on MBs. The newest 123 which people love to convert, are 25 years old. Any car that old has issues despite the fuel type. And most cars that are 25 years old, if they've made it that long are far beyong their prime, Mercedes included, and probably well on the way out. It all comes down to how it was taken car of. Some cars definitly have a better chance of making it a bazillion miles but they have to be well cared for, but even then they don't live for ever.

Might be, but I was talking about Mercedes diesel engines. I loved these cars for a long time and it just pisses me off seeing people screwing them up with bad conversions. Use VWs for that

I'll even let you pick the car, check my sig for the challengers.

I agree 100%. I have seen about 15 conversions and all of them looked half assed and cheap. I would guess about 85% of them are not done correctly. I'm not saying that a well designed and built system will not work, I am saying that using any fuel that an engine was not designed for can and most likely will shorten its life. Mercedes designed these to run on diesel, the ultra low sulfur crap we have today will even shorten the life.
