Engine Swap or Re-Build on a 300TD

Ok,so I got alot of oil blow by,but it runs great! And eventually I understand all things die, so seeing that Im at the begining stages of engine death, I was wondering, which is the better route to go. Engine swap out or a Re-build. I have a 1982 300TD. And where in the world do I get a re-build kit? Thanks in advance James

Too many variables

I don't think I can tell you which is the better way to go because I don't know your situation and there are so many varibles ie, your budget, your mechanical experience, do you have a good machinist, the availability of a good replacement used engine (which are getting harder and harder to find), how much time you have, access to tools and equipment, etc. A proper overhaul is very expensive, and if not done correctly can be worse that putting in another tired used engine. Overhauling a Mercedes diesel is not like overhauling a 350 chevy. Mercedessource can get you any part you would need for a complete overhaul, but don't be fooled by generic overhaul kits. The engine needs to be completely disassembled, inspected, and measured before new parts are ordered. Every diesels wear patterns are different and some will require a lot more parts than others. An old school machinist with Mercedes diesel experience can prove to be your most valuable asset if an overhaul is attempted.

I would highly recommend you don't overhual unless your Mercedes has an exceptionally nice body, suspension and interior and you plan to keep the car for at least another 5 to 8 years. In many cases you will be better off financially to sell your current diesel and go find a better one.

Is it too great of a sacrelige to install a chevy 350? :) I've seen several older Jaguars with this conversion due to the difficulty in obtaining parts for the British engines. Not to overlook quality the Merc diesel, but the Chevy smallblocks have a long lived quality of their own. I have often thought that a TBI 350 and a 4L60E would be a killer powertrain for a Mercedes with a worn out engine. Just playing the devil's advocate, Chris
