Injector crush washer centers missing? 300TD '85
A couple of months ago I replaced my injectors with new crush washers. Now, after a compression test & valve adjustment the centers of two of the washers were missing (and one was broken, about to fall out!) The injectors were torqued with a true torque wrench to the right amount. Where did those centers go? Did they simply disintegrate like happened in my '78 diesel VW or are they destroying my engine? Unfortunately I also have a new noise at certain RPMs and when shutting down.
