hi would injector cleaner harm injectors as i want to get rid of noise so i can sell car.

hi i borrowed leakback tester of mate and done 2 tests and both had diesel in number 3 bottle and rest were empty so does this mean faulty injector and should i take them to specialist

[nicko500s]

IDK anything about leak off tests so cant help with that but I have used injector cleaner that you add to the fuel tank, I was recommended to use millers, I think I read somewhere that euro car parts sell it or perhaps ebay?
My friend has a garage and he has a little tool for testing injectors, you put some fuel in and set the pressure then turn a handle which builds the pressure in the injector till it fires, hopefully at the right pressure and you can check the spray pattern as well as it fires, I wonder if you could borrow one to check your injectors?
Some people use a sonic cleaner thing that vibrates the dirt off of things to clean the injectors as well.
Hope this helps.
Found this.

hi what make are injectors on my mgzs td on 2003 plate thanks

They are bosch 2 stage injectors. Leakoff tests won't usually tell you anything on these injectors as they aren't electronic.

Testing them at a diesel specialist may cost less than you think. I used to get charged under a fiver an injector when I last had them done. (with this refunded against any work needed).

If one injector is different to all the others however then this isn't a good sign.

thanks etv n03 injector was releasing more diesel than the rest but when i took them out 2 of them did not have copper seals so have took them to diesel specialist and he spotted no1 was black so was leaking through the seal but said he would test rest will let you know how i get on he said cost was £6 an injector

Check that the copper washer isn't still in the hole in the head. To remove simply push a pencil into the hole and the washer will stick to the end and can be lifted out (its a simple trick but a really really useful one!)
