So after having to get my car towed back 300km's last weekend due to a leaking injector, I pulled it apart this morning and think I have found the cause...
Would this cause the injector to leak severely ? ?
All the injectors were ultra sonically cleaned and new o-rings etc put on them less then 3 months ago, so i am assuming that faulty installation is the cause of this as the other 3 are fine ??
Now that I have taken them all out for inspection, do I need to fit new o-rings prior to installing them again or will they be OK ?
Also, can the injector leak internally and find its way out of the section between the actual injector and the electrical connection ? or is that all molded together and no possible to leak ?
On the fuel rail, there are two items, one is the fuel pressure regulator, and the other I don't know what it is ?
Regulator : ? (on the return end)
and this I don't know ? (on the incoming end)
For this other one, there is a small Phillips screw in the center of that top hat looking thing that can be screwed in to open the valve and allow less restriction, or screwed out to add restriction. I am guessing this is the regulator ? But everywhere I read seems to indicate that the regulator has a vacuum line attached to it, like the first pic does.
My screw is fully wound in which is allowing NO restriction, so does this mean my fuel pressure will be incorrect , and is this how I adjust it but screwing that screw until I get the correct reading of a fuel pressure gauge ?
Lastly, what are the affects of running fuel pressure too high or too low ?
I am running a microtech ecu which has been tuned according to the way the fuel pressure was (incorrectly) set ...
Thanks a lot for your help guys
