Ok, About the stuff thats wrong with the car.

Dash lights are probably the reohastat (sp), its underneeth the button to reset the trip meter, it can be fixed, might also want to put in new bulbs at the same time.

- I have no dash lights, maybe once in a while they work but not enough to count.


- my left turn signal flashes like there's a short in it, it's got a new bulb, maybe relay?
Does it flash super fast, it might have the wrong bulb, try swtiching the bulb from the left to right side, and see if the bad flashing follows the bulb.

- a slow steering fluid leak
try to find where the leak is comming from, if its just lines it could be easy to fix.

- repair shop says I need all new belts and hoses
Just have them changed, good peace of mind.

- certainly need a new paint job and windshield
Get it done if your gonna keep the car, or just live with it.

- also, I'm missing some of those lug things that cover the wheel bolts, where can I get those?
ebay, or you could take them all off.

- the hood vibrates now on the driver's
Check the wheel balance on the driver side, any wheel wobbles, steering shakes?

Seriously start changeing your oil sooner, aim for like 2800miles, Use a good quality diesel oil.

The engine might be fine, then it would probably be worth keeping.

Do you feel like learning to fix the car yourself?
Still, the engine should not be burning oil at ALL past 3K miles if one is using at least a CF rated oil for ample soot suspension.

My 350SD began showing symptoms of burning a quart every 2500 miles.

All the problems are pretty typical W126 issues and nothing to major. Except the oil buring, that is a sign the end is near for that engine. If it wasn't for that it would be worth fixing all that stuff if you are able to DIY. If you are not then its probably time to move on. These are old cars and they all have a to do list, you need to be able to fix them yourself a little bit at a time to make them worthwhile driving. Unless you are just looking for a cheap beater to drive into the ground, then just don't fix anything.

If you are just looking for a decent daily driver you can get late 90's E320's for $10k these days in good shape, its hard to justify not getting something newer without the habitual "to do" list.

Heck yeah! I even considered taking a diesel automotive class at the local tech school, but I've since moved and can't do the commute.

I thank you all for your input - I think I'll give the DIY route a chance and lean on all of the knowledge here. My next project is learning how the change the oil I guess

It's saving grace to me, is that a 350SDL is rare.

Well, you can have a nice paint job done if you have connections for sub $1k. 3.0L blocks I can get easily, I have seen complete long blocks for under $1500 with warranty.

HVAC stuff to me isn't a big deal, if you farm it out go ahead and be ready to grab the ankles. Most of the other junk you listed (turn signal, power steering, dash lamps, etc) is typical old car. You could have that crap knocked out in a weekend no sweat.

How's the suspension?

If the seats are not cracked or ripped, that's a BIG plus in my book.

If the 603.970 in my 350SD goes, I know who to call!

Suspension seems fine to me, in my infinite wisdom regarding these cars. Interior/seats are fine too. Okay, so I'll try to do my own work on it until I reach my level of incompetence (I think I'm already there). So what kind of book do I need and where do I get it? I don't even know what the things in the engine compartment are called or where they are, i.e. where the vacuum stuff is for the a/c. I need the most basic guide there is. Or is there a web site with a schematic on it? Thanks!

WVO/SVO + 603.970 Hypothesis...

As I was driving the other day, I had a thought about the cursed rod-bender 3.5L 603.970 that some of us have in our 350SD's, 350SDL's, and S300D's...

In a previous thread about these motors, BC mentioned that a likely cause of the bent rods in these motors is high cycle fatigue - that after a certain number of cycles (that number being different for each individual rod in each individual motor based upon its construction, use & maintenance, environment, etc. but seemingly a lower number than the time-tested 3.0L) the connecting rod gives way and bends due to the extra power being too much for it to bear. Here is the post from that thread:

Quote:
Originally Posted by Brian Carlton View Post
While it's certainly possible that certain rods are defective from the factory, if they are forged (likely), the chances of them bending in operation due to running over the design loads are minimal. In any other engine, you can run the rods just about forever and never exceed a design load.

A far more likely scenario is high cycle fatigue. It's related to loading, however, is governed by the on and off cycling of the load. The distribution of failure in high cycle fatigue is huge. One rod may fail at 4,000 hours. The next rod in the batch may fail at 40,000 hours. It's not easy to define high cycle fatigue life. Jet engines suffer from this malady and all of the rotating parts must be scrapped before the very first one of the group suffers from high cycle fatigue.
Since the power that bends the rod comes from the BTU output of burning fuel, (i.e. #2 diesel) would it not make sense that burning a fuel with lower BTU output (i.e. WVO/SVO) could create less power and therefore contribute less to the potential bending of connecting rods in these motors?

Assuming (yes, I know what happens when we ASSUME) that the high cycle fatigue theory is accurate, and setting aside all other potential problems associated with WVO/SVO use, would it be possible to say that burning WVO/SVO in a 3.5L 603.970 might help extend the life of the rods and thus the motor itself?

Hey, call it wishful thinking if you like! I just like my car and I hope I can drive it for a long time. Therefore, I am trying to think of ways to help prolong its life, especially since it saves me a lot in fuel expenses.

Sorry - I now realize this probably belongs in a new thread.

If you fill the engine with the prescribed quantity of oil and you go nearly 3000 miles before it needs oil (as indicated by the dash warning light) I think you have a wholesome, but slightly tired engine. Find out where the oil all over the engine is coming from too. A clean engine is much more torlerable to work on, and frequently easier to work on as well.

I would invest in a bit of spelunking to figure out if the engine is wholesome or not before I would go the route of fixing all the easy stuff around it. If you get into the car and spend $1k on it and then find out you need a new engine you will feel trapped and be a bit less than happy with the advice offered here. Jim

Most of the people here are more than welcome to help, some don't mind lending a hand either! I have a copy of the Factory Service Book, but it's about 300 miles from me. I can try to copy it when I return if that will help.
