690 injector cut open.
« on: February 20, 2015, 10:09:50 am »
Had problems with an injector, read on the net how to clean it with a car valve etc, works temporary because its actually impossible to get the dirt out once its in. Would last a couple days then start with a back fire then splutter. So i cut it in half to see how it works. Everything including the movement is miniscule. So i took my spare injector that had also given the same hassle to a professional, he explained the only way to clean it is with ultra sound machine for 4/ 5 hrs. costs R250.
Both inj gave the same symptoms, and eventually took the pump out and changed the fuel filters, cut the filter open and even though it had supposed to be have been changed 5 months at the dealer it was pitch black.?
Bosh chap says even the spray pattern has changed after the cleaning.
Will try post a pic of the halved inj.

Something to think about...
When you complain, you make yourself a victim. Leave the situation, change the situation, or accept your it. All else is madness.
