Sir, Would you know if there are nozzle tips available in the market for Rover's 200TDI? They only sell whole injectors and someone told me it is only the tips that are needed to be replaced to make it efficient again.
Thanks for the help

Rover 200TDIs use two types of injectors, depending on the year model. Bosch has nozzles and service parts for both types, and you don't have to replace the whole injector.

Most common we see here are the '96 to '98 Rovers, which use the 2.5L 6 cyl. BMW turbodiesel. Do you have the same car?

See copy attached pics of an Isuzu 4JG2 VE rotary injection pump, and it's various accessories.

Pic 1: Pump mounted on the diesel test stand
Pic 2: Throttle potentiometer on the left and turbo boost compensator on the right
Pic 3: Idle-up device and cold idle device
Pic 4: rpm sensor

I do hope these pictures help you. And if you have any questions, just ask.

Bye,

Dieseldude

Vehicle is a Land Rover Discovery 91 model using a 200Tdi 2.5L 4 cylinder engine. Hopefully you guys have a replacement!! I heard there is a Denso nozzle that is similar but hearsay lang siya - I have to research on it pa. Thanks a lot for your reply.

Bosch nozzles and parts are available for your injector.
Denso will not have replacements for this.

Our ESI shows that your Discovery used two types of engines which again have two different injectors. Parts are also available for both. Send me the parts numbers inscribed on the injector itself. Or you can bring your car here.

By the way, why do you want to replace your nozzles?

You can call me at 411-3711 to 13, ask for Jake.

Actually I want to have it checked first to see if it still atomizes the mixture well. Well if it is worn na then I would want to have it replaced na. My disco blows black smoke na and there is a bit of power lag when accelerating. I'll give you a call on monday

Checking your nozzles will entail dismounting, injector testing, and injector re-installation costs.

Inspect / replace your air filter element before considering injector repairs as your engine may just be starved of air. This might cure your black smoke and power lag problems.

Good luck.
