Injectors Leaking

Should the injectors on a 200tdi have o-rings. There is a grove about an inch up from the nozzle. I started the engine for the first time today and on two injectors fuel was spraying from around the injector. I put new copper washer in it when I cleaned the injectors some time ago and I don't remember any o-rings before.

No o-rings per the parts manual.

No, no O rings. just the copper washer. which can be a royal PITA to get to seal properly.

Best bet is to stick the new seal to the injector with a little bit of grease, then gently lower it down into the head.

Trouble is there's no real way of telling whether it's sealed/seated correctly until you start the engine.

Also make sure an old copper washer is still not down in the hole. Had a head redone and a injector pulled which was frozen in place. The engine shop left the old washer which place - it also needed persuasion.

Those can be such a pain, especially in #4. Did you replace the washers with the type that can be mashed or a flat just a flat washer?

I replaced with the flat ones. I think I have some crush type in the gasket set so I'll try those. The diagram in Microcat shows both, is it both or just one of either? Also I noticed some carbon buildup where the washer sits in the heads so I am going to figure a way to remove that as well.
