Any Major Problems with 300Ds?

Are there any common problems that are big ticket? (anything over 200 dollars?) Are the turbos in these long lasting, or do they commonly break. Also heard how awesome these engines were on alt.autos.mercedes. If treated right, how long should these engines last?

It all depends on oil changes and how well it has been taken care of. 500k miles on the bottom end and 250k miles valve guides and seals. Timing chain/guides around 150-200k. The trannies will go a long time too with regular fluid/filter changes.
You will need to replace suspension parts once it gets over 150k miles - tie rod ends, ball joints, etc...
I just replaced the valve guides/seals on mine at 230k miles and I am sure it would have gone longer, it was not using any oil but the cooling system was remaining pressurized over night (a sign of a weak cylinder head gasket in my opinion but there are different thoughts on this).
These engines are worn out when you can't keep oil in them because it is going out the tailpipe but they will keep running. You are just putting the "fuel" in the crankcase instead of the fuel tank. One thing I have noticed about Mercedes is that they will give you plenty of warning before they leave you by the road.

Turbo drain seals. Royal pain in the a** to change. $2.00 part, dealer wants $700+ indy wants $500+. Do it yourself for 6 hours of labor and some tips from this forum.

I dont think I will ever get tired of it

I love the classic styling of the W123 chassis. The reliability, ease of repair, and safety all seem like a good combination for a first car for my son. I am willing to pay up to 3k for a good one, but will prolly get one from dealer friend up the road for 2500. Thanks for your input. BTW, what do you mean turbodiesel when you say there is something wrong with all of them?

It was just a joke, that there is something wrong with them referring to you getting tired of driving them.

PLEASE specify if you are referring to early 300D (W123 chassis, 1977-1985) or the later model 300D (W124 chassis, 1987-1995)! They are TOTALLY different cars with TOTALLY different "problems", and they're both "300D".

But for either, the turbocharger itself normally lasts forever. The engines if cared for properly are usually good for 300-500kmi. The later OM60x engines are more fragile due to the aluminum head, but will last just as long IF they are maintained properly (particularly the cooling system).

If I listed all my benzes in my sig I think it would take up 1/4 of the page I got my first diesel, an 83 300D in June of 2000 with 179,000 miles. I still miss it, buy "car54" here has it now and I get to hear all about it often
