im just going to leave this right here

this is a tread in process

i did this as part of my engine rebuild. i swapped to the newer ev6 injectors because i had a set laying around and one of my older ev1 wasnt passing the resistance test.

i am in the process of building a bench cleaner and flow/test stand.

since step one of cleaning a injector is to replace the filters ill just post up a quick how to now, and when i finish the cleaner/test stand ill add that to this thread.

BTW THIS SHOULD BE THE SAME FOR ANY EV6 BOSCH INJECTOR

"rebuilding" is easy all you really do is change out the filter and the o-rings. you can order up a kit online. this is pretty standard on how to do but to cover my butt... this is a bosch ev6 injector from a 4.6 merc, same injector in the 5.0s and some 5.8s it is 18.25lbs/hr

step one: check resistance aross the coil in this case 11-18ohms. just run your mulitmeter to each of the injectors electrical prongs. all of my EV6's checked 14ohms...

step two: remove the old o-rings and cap

step three: wipe off all the dirt you can find

step four: remove the old filter

step five: install new filter, o-rings and cap

step six: finish beer and start a second... or third... or fourth cus your DONE

the next step would be to flow clean but that'll wait till im done building circut cards -more on that later

 

But is it worth all that doing when new ones are affordable enough. Yea it's something cool to tinker with though.

 

Thanks for sharing the illustration. I'm sure it will help some guys out.

I've heard of people soaking them in Berryman's or similar cleaner. I wonder if thats a good idea or not.

 

affordable yes... but the kit (for 8) is $25 bucks... and i dont see the need for replacing with NEW for more money when these check good. and like i said this is the begining of a bigger tech thread for cleaning/flow checking injectors to this can be done with about any kind of EV6 bosch injector like the 30lb injectors that are stock in some turbo volvos that ARNT as cheap. I had these "new" EV6's in the garage from a previous tear down.. but out of pull apart they are $3ea? or the pocket discount price of $free.99

i am hessitant about soaking anything that has a electrical connector in any fluid expecially a solvant
