Probably melt. haha.

I don't like re-using washers, but I have in the past where I've been stuck and a friend of mine has never changed his originals, just annealed them every time he pulls them out.

Nervertheless, check them for condition, and you'll most likely be okay. The main issue with sealing, as I said in response to a similar question on here yesterday, is the cleanliness of the injector nozzle holder and the bore.

 

Search on ebay for 'freelander injector washer'

The 97-00 freelander diesel was an l-series.

 

Definitely not!! The injectors need to have a good seat contact to keep them cool (they get rid of temperature from the nozzle by having a good thermal "bridge" into the cylinder head). So the injector washers are more important than just sealing the injector to the cylinder head.

If you cannot get new washers, the best way to re-use the old ones is to anneal them - heat the washer up with a blow lamp until it is glowing a dull red, then let it cool down slowly in air (don't force cool it with a fluid). This will soften the copper again, and allow the washer to reseal between the injector nozzle and the cylinder head.

New washers are always better than re-use, because each time the washer is used, it squashes down a bit. The height of the washer is important for emissions - which includes smoke (i.e. MoT test) and is developed to the nearest 0.1mm in engine development.

 

Many thanks for your answers! I think I'll try annealing them, if I cannot find new ones.

 

rimmer brothers mate. less than £1 each

 

If you are desperate, you can reuse them if you heat them to red heat over a gas flame and quench in water which removes the oxide. This softens the copper and allows them to bed in again during which time they will work harden as copper does.

You are ok to quench copper it won't harden it, if you leave to cool slowly then the copper will be coated in a black oxide which is no big deal. Copper work hardens only.

 

Pretty sure you can get them from any Land Rover dealership?

 

OK, thanks! Just out of interest, as Skye_rovers stated, what does washer height have to do with emissions? That's interesting.

 

the positioning of the injector nozzle and piston bowl are quite crucial, deviations from the design can affect combustion which i think is the logic behind this.

ive never had a problem myself, but obv new washers are absolutely preferable

 

Annealing is a good idea. Had some trouble with my Deutz F5L 912. The original washers were aluminum and fiber and stuck with 30 years of dirt and I didn't have the proper tool and boogered the seats a little getting them out. Had to get a 22mm end mill and refinish the seats to get a good seal again.

Since then have bought some asbestos/copper crush gaskets that I'm hoping will work if it ever leaks again. Got them from Aircraft Spruce.

Had read about annealing, but for some stupid reason did not try it. Typically will rub used washers on concrete or emory cloth and reuse.

Ebay had a kit, from the UK I believe that had cutting tools for various injector seat refinishing.

Yeah, after cleaning the injectors I fitted them again yesterday using the old washers which seemed to be fine. Just cleaned them in alcohol and rubbed them a little on concrete. Actually, it was more difficult cleaning the bores as they are quite deep. Then put injectors on, drove the car for a while and there were no leaks at all. Hope it stays like that. The car now is a little bit faster than before. By the way, injectors came out quite easily, a little twisting with a 15' spanner and I could pull them out by hand. I know I should have ordered new washers but I'm not in the UK and it would have probably taken ages. Thanks for all your advice!

 

Although the car is more enjoyable to drive after cleaning, the mpg seems to have suffered. Apparently more fuel is being burnt now. Oh well, we cant have everything..
