Either put your parts back on or have a "TRUSTED" MB indy do it for you that maybe someone on the forum in your area can provide.

And dont feel bad alot of us have "played" the lets just see how this thing drives with this stuff game. (myself a very long time ago

)

I don't think it's had pure soybean oil, as it had about 1/4 tank of diesel when I put the first 5 gallons in, then tonight, after reading some of the comments, I went and put 5 gallons of diesel in it.

So now what? If I need to eat it and chalk it up to experience, I'm okay with that, I messed up, I learned. But is it too late already? If I just don't run any more vegetable oil, is that enough, or should I remove the system and put the original parts back in the original places?

Yep, I'm really beginning to think I made a big mistake.

Definitely a mistake, but not too costly a mistake at this point. If I'm in your shoes, I get all traces of that veggie oil outta there ASAP. Find a very local mechanic, guys here can refer you to one, which area are you in? ..and get rid of the lovecraft parts, yes, try to get your $$$ back but don't be afraid to eat the loss and chalk it up to experience. good luck

Not trying to kick you when your down, but did you do any research on this forum regarding the engine in the 300SD model you purchased? Hopefully the rod bending nature of that engine has been addressed by the previous owner.

For what is is worth, if they installed a Davco 234 fuel filter that you can replace the element and live in SoCal. Then you could run a blend of rug and veg and should be fine. Do a search on Blends on this topic. But if they installed that "lifetime" fuel filter, change the unit out for a replaceable element type and run the blend, or just remove the whole system and run straight diesel.

I think there's probably a snowball's chance in you know where that I'll be able to get my money back. In addition, when they did the conversion, they took a part off the front of the motor and replaced it with some sort of machined aluminum thing. I believe they called this a heat exchanger. Anyway, I was dealing with a bit of pain that day, and completely forgot to ask them for any parts they removed. I'm pretty sure that they only removed that one part, but I have no idea what it was now.

I live southwest of Portland oregon, and at this point, I know I'll need to take it somewhere to "put it back" the way it's supposed to be, if for no other reason than I don't know what part(s) are now missing. Yes, I was that stupid.

Now, it might be a bit of time before I can get the system removed and the car put back to stock, can I drive it on regular diesel 2 until then, or is the system so bad that I can't even do that safely?

It's all right, if it needs to be said, it needs to be said. Anyway, I bought the car last week, and didn't find this forum until last night. I read some about the rod bending problem, but thought that was in the six cylinder engines, not the five. How would I know if I have the problem? Are the symptoms obvious? Do they happen over time, or is it an "all of a sudden" type of thing?

I'm waiting for the other shoe to drop now, hopefully there isn't one, but who knows?

I am very happy that I found this forum early on, instead of after my IP and injectors got completely hosed, and I'm looking at my car on the back of a tow truck.

$!#%&

It has a six. Dang it. When we bought the car, we'd been looking at quite a few others, including some 300Ds that had the five cylinder engine. Man, it just keeps getting better.

Cetillim relax, it'll be alright. You have found the right place to get your car running like it should. Hang in there. These guys on this forum can help you do stuff to that car you won't believe. Good Luck.

#**204** 07-04-2008, 05:07 PM

You can drive on diesel fine until you get the new parts but the stock filter is much better than the sock zip-tied over the mesh water strainer they installed.

The 1992 300SD is the six-cylinder. You have the problem if the engine consumes about 1/2+ quart of oil per tank of fuel. Nobody knows the actual cause so how sudden or gradual it happens is not really known.

Thanks a lot to all of you. Part of my issue is that I really don't buy a "new" car all that often, this one is to replace my 1993 Toyota pickup that I did buy brand new, and drove until this year, to 308,700 miles. To say that this was an upgrade would be a grand understatement; I don't believe anyone in my family has ever had a car as nice as this one, and I want to have it for a very long time.

When I purchased the 300, it was more or less to have a dependable, reliable car, but yeah, there was a bit of "ahhhhh, now this is a car" in there too. I did buy a diesel partly because I believed the stuff about the S/WVO, but also for the better efficiency of the diesel and the reliability. I commute 30 miles each way to work, so I'm always looking for a way to make that more affordable.

At this point, the money spent on the conversion, as well as the money spent to put it back the way it was, to me, is something I'll consider a learning experience.

I'm reminded of the saying: It could be, that the entire purpose of your life, is merely to serve as a warning to others.

Probably not, but I find it to be somewhat of an entertaining phrase.

crashone · #**206** 07-04-2008, 09:52 PM

nah my purpose is to be a good example of a bad example of how to do things. See I'm not completely worthless!

Chadahar · #**207** 07-04-2008, 09:53 PM

Remember the saying "May you live in interesting times." I think we've all had "Interesting times." Some more "interesting" than others.

I just acquired a 300SD myself and am reading and researching a lot about WVO/SVO, Biodiesel, and the like. I know not to use Lovecraft. Right now I'm just flat tickled with the mileage I'm getting on #2 diesel. A good 11 MPG over my 560SEC in town and I like that a lot.

cetilim · #**208** 07-05-2008, 03:58 PM

I've been looking at what Lovecraft did to my car, and it doesn't look all that complicated to remove. I do, however, seem to be missing the filter at the front of the motor. When I look in the service manual, on page 157, it is designated as number 604. Is this a part number, and if not, does anyone know where I can translate this into a part number?

And I imagine I'll get a great big "duh" over this one, but after looking at the car a bit closer, and taking stuff off and putting it back, I am amazed at how easy this vehicle appears to be to work on. I'm already trying to find another one to buy for my wife, I really am impressed with these vehicles.

Chadahar · #**209** 07-05-2008, 06:20 PM

DUH!!!

OK! You asked for that one!

Once you get into them they are a pretty straight forward to work on. I'm just learning the diesel too, but been into my two gassers since last Sept. and knew nothing of them before that.

Lots of help here too. and in the DIY articles and in the Search this forum area too.

There is a possibility thet M-B has already replaced the engine. They would probably have the records if they did. There have been no reported failures of the #1 rod on the replacements to my knowledge.
