leaking injector om617
The overflow lines were for sure leaking but I think that it also leaks out the sides. Like from the threads where it would separate into parts, not from where the fuel is fed in.
What's the treatment to remedy the leak? Do the separate halves of the injector need to be torqued to a certain tightness? Or is locktight in order?
Must I have a new heat shield on hand it I pull the injector off the head?
Nice body, tons of ridiculous mechanical issues - 300d turbo 82' /motor 85'
On the new car it seems like the #5 injector (is that the rear most?) is leaking.

You should replace the shield, but its quite possible to bang the center back into place and re-use it. The inner diameter is almost at the same height as the top surface (looking at the profile) when new.

Over tightening can cause Hard start cold,noise,rough idle,poor performance.
mbz says 50lbs. Distortsion of barrel occurs , this causing pintel to over heat,begins to stick, renewal will become necessary.This does take some miles to happen. (Leak) Caused by uneven mating surfaces in injector. Repair, Remove inj. separate, hone all mating surfaces (600 grit) wet /dry on flat surface, using figure eight motion,clean all parts ,blow off,lube, retorque 50lbs install in head also 50 lbs. Careful not to lose shim under spring in inj.
