I have a '82 240D automatic that I'm trying to find out the engine number to order parts. The PO told me that the engine was swapped for a lower mile (no idea what happened to original engine) unit. I found the location where the engine number should be, but it looks like everything after 616 was ground off. There are marks consistent with a wire wheel on the number area.

According to this post there is also a plate fastened to the block with the number, but doesn't specify the location. Where is the plate usually located?

I'm the part I'm stuck on is a thermostat. Going through both engine number selections, it seems the part number is the same. Is there a different in thermostats, or is it just a opening temperature difference?

You have an OM616.912

Put your VIN into this place and it will tell you.

There is a different seal for the two different types of thermostat. If the thermostat is mounted vertically you have a later type engine, if it is mounted horizontally you have an early engine.

Sometimes an acid etch can bring out the numbers.

I had tried that and couldn't get to the site, now it works. Must have been OpenDNS burping up.

Definitely a vertically mounted thermostat.

I'll have to try that. I cleaned the area with degreaser and it just brought out the gouges better. Its quite clear where the numbers were ground off.

If it makes any difference, the number cast into the block forward and below of the stamp site is 616 011 28 011. Which I believe just states that this engine was mated with a manual transmission originally.

The Russian site no longer seems to run US type VIN numbers.

Works on both of mine.

Don't why but this the error I get:

Datacard for VIN WDBAB33A9EA06835 is not found
1) VIN was misspelled in the request form;
2) VIN was erroneously read from vehicle body or documents;
3) VIN is not of an original vehicle and was forged by criminals;
4) The vehicle was produced in late 2005 or 2006, and is not included yet in our database

I used to be able to run it before.

Drive that engine like you stold it. Even if just an accessory after the fact. Some engine rebuilders ground off the block serial numbers. On the otherhand..............
