Requesting some advice...may look at a vehicle today
Hi everyone,
First post here. I am new to the world of diesel Meceredes, but excited about getting one. I may go look at a vehicle today. It's a 1981 300D (non turbo), 182K miles, owner has records that among other things show a transmission rebuild and AC service (works). Asking price is $3000. I am most concerned with reliability. Is the 300 non-turbo any less reliable or more maintenance intensive than the 300 turbo or 240? I've heard some say the 300 non-turbo is not as reliable. Also, is power on the 300 non-turbo a big issue? And lastly, being in California how much of a concern is a trap oxidizer (I don't know if this one has it). Here are photos of the vehicle described above. I welcome any thoughts, advice, and answers to my general engine questions. Thanks . |

Doesn't the 300 and the 300 SD use the same engine, only one is turbo and the other isn't. I think the reliability issues are in the 300 Rod Benders and not the one you are looking at.

I'm no w123 guy, but it looks nice, and in Cali with those miles for that price, it sounds like a reasonable deal.
I would think that if it didn't have a turbo it would at least be as reliable, if not more...at the very least, there would be less to worry about under the hood!

Having had both, to some extent I prefer the non-turbo. Or at least my 1980 300TD had a lot of pep. In addition, you have one less part to deal with (the turbo). I would say their reliability is the same. Maybe even better for the NA. Check for blowby, vacuum system all working (central lock works), condition of axle boots and flex disk, tranny shift, ball joint and tie rod end condition.

Reliability is about the same, NA is simpler so less to break but turbo is not usually a problem. NA engine makes about 85 HP, turbo has about 125. Fuel economy similar. Only 1985 has trap cat in California cars. 300D and 300SD have same engine for same model year.

I have owned a non turbo and a turbo
I owned a 240 non turbo manual and satisfied with it and its fuel economy. I owned a 77 non turbo which is the same engine that you are looking at in the one you want to buy. it only got 20 to 22 miles to the gallon highway and very little power. If you are going to spend 3000 on a car that has almost 200,000 on it...i would say have the turbo. And no there is a differenc between the turbo and non turbo as far as the engine goes. The cam is different and is marked at the end of the cam on the fire wall side by a number to indicate what type of cam it is. I believe for the non turbo is a 08 and the turbo cam is a 05. I am not quite sure about the numbers but the cam is different for a turbo vs. non turbo.

Depending on where in California you live, you need to consider the fact that there is a significant difference in power between a turbo and non-turbo at altitude. Reliability is a non-issue.

We have owened quite a few 300D NA and Turbo, here is a break down
300D NA: THE good: Idles smooth, More engine space to work in, smooth highway ride The bad: 21 mpg, Rpm @ 70 MPH is @ 3500 RPM, Slow pick up. 300D Turbo : The good: Fast, Better Fuel economy, Lower rpm @ 70 MPH 3000 rpm, AND an awsome turbo sound if is straight piped exhasut and intake changed into a K&N style intake (K&N filter not reccomended) The Bad: Loud & A little rought Idle, turbo LAG, engine runs a little rough in high rpm (highway cruse) So there it is... IMO GO for a 300D or 300SDL with a OM603 engine is way smoother, runs better,very smooth, LOTS OF POWER!!!, and SUPERB MPG but be careful for these engine are prone to have CRACKED CYLINDER HEAD... Unless if head is greater than #14.

I really like my '81 non-turbo. I get about 24-25 MPG on the highway.
I think when buying your first MB diesel the biggest thing you have to allow for on these cars is the noise. It's not quiet like a GM car inside. If you're OK with that it's a wonderful car.

If the service records go way back and verify the claimed milage I would tend to buy it. The front seat condition does look like the car has under 250 k if taken care of.
Too many examples with this cars claimed milage have a worn out drivers seats and not many accessories are still working. .Take care of it and you should see your money back. If you are mechanically inclined a rear end change would drop revs on the highway. The revs on the highway do not hurt the engine though. Some people just like a slower turning engine at speed. Great starter diesel. Really good true fairly low milage examples like this one may be pretty scarce in reality. This total milage accumulated is up to you to establish again as the majority of 123 diesels are not indicating their correct total milage. Again if all features like air conditioning and cruise control etc are working someone has taken good care of it. Of course if turbo 300ds are available in your area in this condition for this kind of money you should grab one of them. The yellow spotlights on the front of the car are replacement units or the car was garaged a lot in it's lifetime. The yellow usually fades with the years in my experience especially with a car sitting outside all the time. |

Are you sure 123's have cylinder head problems? I thought it was only the 124 with the aluminum head. 123's have a cast iron head, right?

My opinion:
If the car has decent service/repair records, passes a pre-purchase inspection without any major problems and is not a victim of extensive rust or previous accidents then I say go for it.

What kind of GMs are you talking about?! My 300SD is way quieter than any GM I've ever been in, but my 240D is LOUD (a combination of removing the sound-deadening material from the floors non-stock exhaust and the limited sound-deadening material that came on the 240D from the factory.

All W123s have a 61x all cast iron engine. The 603 is the one with the head crack issue.
