Having a problem with a leak around fuel injector on a D7 3T. Could hear leak and looked up in parts book to see if there was a seal between injector and pre combustion chamber. Ordered seal and I have tried twice to install. Did not see any evidence of old seal. Both times seal has flattened out and tore.
Anyone have any ideas, is there really supposed to be a thick seal between the injector and chamber. Seals look like thick cork. Could I use maybe a copper washer as a seal?? I am sure to be losing power because of this.
