'82 300TD - Common problems? - PeachParts Mercedes-Benz Forum

I just bought an '82 300TD. It has 234,000 miles, and seems to be very nice. What are the weak points of the W123 diesel wagon? For example, at what intervals should the timing chain be replaced? I hear it has a specific life.
Thanks,
Kirk

The stretch of the timing chain can be checked. Many people believe that with adequate oil changes, the chain should last the life of the engine.

There really aren't alot of weak spots provided the engine hasn't been abused. With 200,000+ miles, as you might expect, you may have some maintenance issues pop up once in a while (weak starter, rear axle shafts, vacuum line leaks, etc.) but no really major areas to worry about. If the prior owner was good about maintenance many of the above wear items may already have been done. Sometimes they last the life of the car. The best advice I can give you is keep the valves adjusted (every 15,000 miles) and change the oil regularly (preferably as hot as possible). I've had 100,00 largely trouble free miles on my wagon and am looking forward to at least 100,000 more. It's a great machine and pretty easy for a DIY to take care of. Enjoy it.

as said, not really a lot of weak spots. but regarding wagon versus sedan, search this board for rear suspension knowledge. plenty of tidbits in here...

If you are talking about the wagon (300TD) you should check the rear hydropneumatic struts. They tend to leak and need replacement (alot of $$$). Make sure it sits level and bring your friend, make him sit in the back and the rear should pump up back to level. That's really the only weak spot with the wagon. It's drivetrain is damn near bulletproof.
