Hi guys,

I'm still not convinced my delivery valve project is a success just yet. I replaced them last Sun on my 87 300D and everything went well and I kept everything clean. I swear I hear a slight hammering and pinging sound at idle and you can often hear it right around 1k rpm. I replaced them because my small leak grew into a small "river" and I couldn't believe how much diesel was sitting in the lower plastic pan. Now, the car idles just fine, has relatively no smoke and has lots and lots of power! Oh, no leaks either! What gives? Do you think I should re-check my torque on the holders or simply start with injectors or just live with it since everything else is fine. I thought that improper torque or a warped pump body would offer lots of smoke, vibration and a rough idle... I have none of this. Do you think one of the seats isn't sealing properly and I'm seeing the effects or maybe I have a bad injector? It has 215k on it now and I believe was quieter and "leakier" prior to my project. Please let me know your thoughts as I haven't found anything "definitive" in my search efforts.
