Hi Mac, I don’t have the exact one I bought to hand but I’ve just looked on eBay and this is what you need . You will also need a slide hammer for removing an injector plus a bit of patience. Took me an hour of tapping with the slide hammer . I presume you don’t live close to Kenilworth? Happy to lend you both tools . https://www.ebay.co.uk/itm/356481194608?mk...media=COPY

Thanks pal - Had a look yday - not a lot of room for my fat fingers lol

Getting my front lower arms changed at another garage tomorrow and one of the older chaps there is an ex mechanic - mainly engine rebuilds on old defenders! Might ask if he can have a look at swapping the washer out for us for a couple of beer tokens.

Also just on this point is it easier to take the bonnet off so you can get more room looking down on the injectors??

lol 😂 the beer tokens sounds like the way forward and hopefully in your case you can simply change the copper washer 🙏 . If you take the clips off the bonnet struts , the bonnet will then go completely vertical allowing plenty of room …Not a difficult job to be honest . How old is your car, is it a L494? Mine is 2014 with 90k miles and all good now . Please let me know how you get on 👍
