Engine number - How can I tell?
How can I tell which model engine I have on my 4 cyl., 2.3, 1991, 190E? It is Canadian spec., and I see when looking at manuals that there are at least two models (102 and 103 if I am reading it all correctly).

The things you should probably have checked out on your car are:
Front and rear flex discs, front and rear engine mounts (these make a huge engine vibration difference), belt tensioner assembly (you will find out when changing or replacing belt), all cooling/radiator hoses, spark plug wires, spark plugs (non-resistor type), rotor, distributor cap, vacuum hoses going to and from the Idle Control Valve (they become hard and brittle and crack).
As a newbie to the 190, when doing your first oil and filter change, I would also change the differential fluid and coolant unless you know for sure when it was last changed.
Since you are looking all over your car and checking things out, you might want to check out this website for future troubleshooting:

Have fun,

Thank you!
Thank you Tgor and Dave!
The front one has a little play (± 10º), but I've been told that is OK, for as long as there are no ripped bits. (I am assuming that is the same as the "Drive Shaft Flex Joint")
These have been checked and/or replaced! The car was from an MB mechanic and he told me that if there were any (of that type) of problems I could bring it back
These where done too, thankfully, and as well I had it "winter oiled" (read rust proofing)
There's where they are! I actually posted a thread on another place in the forum about it. Great resource!

BTW, there are several flavors of M102 motors, so when ordering parts, make sure you have the right model M102 and know the serial number. Significant changes were made over the years to the valvetrain, the ignition system and other parts, so some pieces for earlier engines may not work on yours.
You will find the complete serial number for your engine stamped into the metal engine block on the intake side of the motor, near the location of the first cylinder. It should begin with the numbers "102"

Mercedes, like most car makers, make production changes in mid-year and therefore it's important to know the serial number. Most of the time the mid year changes were due to parts suppliers, either being changed or a redesign by the supplier when old inventory was exhausted. In a few cases, there were actual design changes to reflect product improvement based on real world experiences.

OK, so here's another stupid question... A previous 190 owner offered me his Haynes book (1983 to 1993 A to L registration). What the heck is the "A to L registration" referring to? Do I even care?
