The M104.980/981 were twins that had VERY few problems. M104.981 was in the 300SL.

The headgasket problem compared to the 104.992/994/995/996 was NON-existent.

I liked those engines as the fuel system was virtually the same as ALL previous 6 cylinders.

CIS-E can be a pain to those NOT familiar with the concept & diagnosis.

Wasn't LH-SFI, only the 1992-93 M104.990 used that fuel system(300SE/S320)
