Title: d.i.y. petrol-injector cleaning
Post by: vinny on 10 September 2008, 21:52:59

hi all,
        is it possible to clean the petrol injectors at home? it could be powered by a small compressor, i`m sure i`ve seen some gizmo on an american website

What makes you think they need cleaning?

Ideally you want to suspend them in an ultrasonic bath and exercise them by feeding pulses through the solenoids while they are cleaning. I would also rig up some means of observing the spray pattern and flow rate so you know if you've improved them. An old fuel pumnp and FPR, rail and a circuit to actuate the injectors. Ideally you want to find a fluid as a petrol substitute with a similar density but not quite as likely to turn your garage / shed, etc. into a fireball. :o

Perfectly do-able on a DIY basis but not sure it's worth setting up for a one-off job.

I've used these people before: http://www.injectorcleaning.co.uk/. Very good service. Injectors come back clean with a before and after report on flow rate and spray pattern. Rubber seals, finger filters and pintle caps replaced with new.

I went to the trouble of getting a second set of injectors to cover me while they were away. Needn't have bothered. The morning after I fitted them to the car the cleaned ones came back. They were away well under a week and I sent them bog standard first class post.
