I found this W124 300D at Pick-Your-Part yesterday, and saw a new way to keep the injector return hoses from leaking!. It is also another use for epoxy putty. It appears that some of the return hoses were missing, and some ingenious person molded epoxy putty around the top of the injector, including the tube nut and return nipples. It obviously worked good, as there was no sign of leaking Diesel anywhere around the injectors. Of course all the injectors rearward of #2 had no way to leak off (nipples plugged with epoxy), so no more leaking return hoses!
