Motor replacement 1994 E500

Hello I’ve had a 1994 E500 for two years now I bought from a Mercedes shop I worked at when they closed down. The previous owner put 168k miles on the car and the chain snapped. I’ve been thinking of getting a replacement m119 from a 94/95 SL500 does anyone have recommendations on m119 variants as I’d keep the original motor but would like the car to run again since it’s been sitting for almost 15 years with a bad motor.

Timing chain breakage is almost unheard of on the M119. Have you pulled the valve covers to confirm this is accurate? Or confirmed the exact damage to the engine? it may be fixable, which would be the preferred option of possible.

If you do need a replacement engine, and can't locate one from another E500E, then yes... a 119.972 motor from a 1993-1995 500SL/SL500 is 100% bolt-in (need to swap the ETA though). It MUST be those USA model years and MUST confirm the engine serial prefix is "119 972". The earlier 119.960 and later 119.982 engines will not work.

If you buy a spare engine, take the time to do ALL the preventive maintenance prior to installation. All external seals including front & rear crank seals, replace ALL upper chain guide rails (not the chain or tensioner though), replace/reseal the cam advance solenoids, drop the oil pan and replace the oil level sending unit O-ring and oil sump pickup rubber boot, and more stuff I'm forgetting. You will not want to do this with the engine in the car. Also remove the transmission and re-seal that as well (every single external seal, especially the front pump and converter seal). Check/replace the reverse clutches while it's apart for the reseal.

BTW, welcome to the forum!

@zmcgee,

It’s a shame to see your E500 setting there next to whatever that red car is w/ the flat. A timing chain snapping is almost unheard of. Take gsxr’s advice he knows these cars well.

It would be nice to see your E500 back on the road. There great cars.

Good Luck😀

The red car is a SAAB 900!

I had need (don't ask me why, it's too embarrassing!) to replace the motor in my early 1993 500E - and followed excellent guidance from gsxr in installing a low mileage 119.972 from a 500SL.

It's a few years ago now, but if I recall correctly, the installation is completely "plug and play". However, you'll probably need to swop the fan clutch on any replacement 119.972 with the fan assembly from your existing engine? This is because I think the 119.972 assembly stands a little more "proud" than that from an original 500E engine - and as a result can foul the rear of the radiator? I haven't checked any differences in the part nos. for the two fan assemblies, but I believe them to be different?
 
Yes! The fan clutch must be from the 500E. The R129 clutch is different and will not fit in the W124 chassis. The engine and fan bracket are the same, the clutch has different dimensions.

I was going off this as a 900 which has different door handles and no 3rd window on the side:

I probably shouldn’t argue with a Swede about Saab car identification 😀
The car that replaced the old 900 in your picture was named 900 for a couple of years until SAAB changed its nomenclature just like Mercedes did, changing the 900 to the 9-3 while being the exact same car.

The five door variant of the car in your picture also have the 3rd side window btw, it only disappear on the coupes for both generations.

Confusing indeed, especially since there was an old SAAB named 93 decades before.

Sorry for the off topic but I do love a SAAB discussion. 😊

Awesome glad to hear!! I know the timing did jump but I’ve yet to take the timing cover off. When pulling the motor does the trans and motor need to come together or can they be pulled separately or which route is simpler as there’s not much room to work with thank you!!

They can be done separately, which I prefer, as then the engine does not need to be angled severely (or, lifted as high). However this will add some slightly different challenges. If you have a lift, dropping the transmission first is less of a chore, but without a lift this could be difficult.

I have a low mileage ( 53000 Miles) 1993 500E motor complete that I would sell for $3000 if you are interested.
