A new way to keep injector return hoses from leaking - PeachParts Mercedes-Benz Forum

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!

Looking at the photo again, I realized the culprit's fingerprint is cast into the epoxy!

Hey, I see what you were talking about. I would say those nozzles holders are done for. Not worth the risk or effort to try to clean them up.

Somewhere there's a "I fixed it" website showing off more wonderful solutions (can't recommend using the energy to look for it though)

🤣🤣🤣

Reminds me of a car I bought as a teen. The unorthodox fixes made the car harder to fix than if the PO had just left it broken. On top of that, he marked every fix with a splotch of nail polish to document that he himself had done the deed

Apparently he took pride in his work. We got pretty deep into the car and were very disappointed to find his marks indicating he’d beat us to it. We’d literally pull a cover off and see the paint mark and scream “oh no!”

His favorite materials were JB weld, safety wire, fiberglass, duct tape, electrical tape, wire nuts and white lithium grease for everything that moved.

A Propane Torch will easily deal with the Epoxy with out damaging anything except the rubber hose. Keep a Fire Extinguisher or a connected Water Hose handy.

The injectors were already out when I started the thread. However, I may heat up the nipples a little to get the epoxy out of them.

,.....Is the name of the site and here's the hyperlink : https://failblog.cheezburger.com/thereifixedit

Bodge repairs are a pisser for sure but often they are good teaching tools as to what can and should not be tried .

On a long trip somewhere in the middle of nowhere a hundred miles North of Bakersfield driving my 300TD with '85 OM617 turbo I started smelling diesel fuel quite strongly, buzzing along at 75-80 MPH I noticed a car came up close behind me and instead of passing he backed way off, and strangely on a dry summer day he had his WS wipers going then it occurred to me I was losing diesel to a great degree as my back windshield was getting covered in the mist of diesel that I was dispersing behind me.
I pulled over on I5 with other cars whizzing by at 70+ I raised the hood and saw fuel spurting out of the #5 return nipple at the firewall

The short hose with that small metal plug that was supposed to be on the last nipple was nowhere to be found.
I searched around and found a loose screw in the glove box that came from who knows where (hey I never throw anything away!) and it was just about the right size so I cut a section of return hose off the long one going from the filter to the IP and stuck that on with the small bolt screwed it into it and no more leak!

I'll bet the other car had a heck of a time trying to clean off his windshield
