[W126 Coupe] Engine replacement

[Gerry Van Zandt]

Oilpan isn't the only difference between the R107 560SL and W126  
sedan/coupe versions of the M117 engine, but yes they are different  
and the SL version MUST be retrofitted for SEC duty..

The oil filter assembly on the 560SL is "traditional" benz whereby  
the canister is dropped from below the car by means of a center bolt  
that goes up through the canister from below, into the housing.

The 560SEL/SEC version of the motor has the more modern oil canister  
lid that is removed from the top, via a bolt that goes down into the  
housing from above.

Both versions use exactly the same oil filter, just different housing  
designs.

BTW the SEC version is MUCH preferred -- less messy, can be done from  
above (particularly in conjunction with a topsider or other vacuum  
oil removal system.

The only drawback is that you don't have to get under the car, so you  
can't see what's going on under there unless you make an effort to.

If you've ever had an oil bath from a bottom-canister-removal setup,  
you know what I'm talking about...

To me, the 560 in a R107 chassis is not as glassy smooth as it is in  
a 126, but that's just my opinion.

Cheers,
Gerry
