Whats the best way to clean Injectors??

Post by joolie »

Injectors are looking a little red on the outside. But they functioned well when the car was running.

Im changing a split camshaft, maybe the head too, might as well clean up the injectors too, whats the best way?

If you have the cash, and there does seem to be something wrong with them, take them to a specialist to be reconditioned. If there was nothing wrong with them, leave them well alone and use "italian servicing" or the standard injector cleaners in your tankfull.
Occasionally constrained by geography. When not driving, can rely on ferry, two wheels and musclepower when a couple of miles as the crow flies would become a round-road-trip ten times the distance.

Be vary wary of the caps supplied by the aftermarket. They are no longer available from Bosch so you have to buy others.

I bought some and after a problem with rough running took them out to find 2 of the 4 caps had fallen off.

If theres nothing wrong leave well alone, thats my advice after trying to be clever.

Diesel injectors are not considered a home serviceable item and are always either done professionally or replaced.


This page is primarily devoted to Land Rover workshop manuals (Complete manuals for download) but there are 2 references to CAV diesel pumps and injectors. The overhaul information is primarily the same for Bosch.

There are many independant diesel specialists who will overhaul injectors for you but currently I think you will find that the price for new from places like GSF are very good.
