Thanks in advance

A diy kit, 4 plastic bottles, (500ml coke) tie a piece of cord round the neck of each seperate bottle and hang in a line from bonnet above each injector, drill hole in tops to feed a piece of tube into, fit the other end of tube onto the corresponding injector, injector 1 to bottle 1 etc, run the engine on idle, if the injectors are ok the bottles will have an equal amount of diesel, if an injector is bad the corresponding bottle will have a different amount.

Search for posts by me Angelo - I posted a lot and showed a home made kit for doing it.
