I just receive my parts, UVC harness, valve cover gaskets, and glow plug and injector harness. The out side harness has the seal but insides (UVC harness) does not, the ones on there now are worn and done. I called the part guy and he say ford stopped putting them on as they were not need. But I like the idea of having them on to help keep oil out. Will it be alright to install with out the seals or, and where can I buy the seals? Has any one on here run the parts with out the seal on the UVC harness?

 

I just put a bead of die electric grease around all my plugs
