300 se 1991
Hi all,
Just purchased a 1991 300 se 126 series with 114,000 miles up for 7,000 euro. The colour is navy blue. Seems to be in vgc. Just wondering what your opinion would be. What potential problems should I look out for.

Check for oil leaks from the cylinder head gasket at the front and rear of the engine. Annoying, but probably something you can live with for a while. Keep an eye on oil consumption. Valve seals on these engines start to leak around 100K-150K miles. Not difficult to replace. MB supposedly used better valve guides in later M103s so that shouldn't be a problem for you.
It's common for serpentine belts to fail around 100K miles. The belt tensioner indicator will be spot on but the belt will be loose. Doing this job yourself will make you wonder if MB engineers have a conscience. Not difficult, but certainly needlessly complicated. If the shift lever is loose or squeaks, it's time for new shift rod bushings. Doing this job yourself requires creativity more than technical expertise and special tools. Search the archives on 300SE for other things to look out for. Sixto 91 300SE 87 300SDL 81 300SD |

You may also try searching the archives for M103, which is the engine you have. In the U.S., 86-92 300E's also shared the same engine as in your W126. There are probably thousands of posts with questions relating to your engine.
You can spend more time reading these posts than sleeping, so be careful!
