Leaking Fuel Injector, Intermittent Problem Options

[74914LE]

Does anyone have an opinion....on what would be causing a fuel injector to be leaking
intermittently? Is that symptomatic of a complete failure about to happen? I have had
them start leaking, and need to be replaced, but never a start and stop. I noticed it dripping
the last time I came back from a ride around town, and started it up today, to
verify if that is was #3 or #4, and it is not leaking now. Even after bringing the engine
up to temp., nothing? Head scratcher. Thought I would ask the question before I start
swapping things out.

It is on a 1.7lt car, and the fuel lines are in good shape.

Thanks!

I had one like that, that leaked intermittently and sent it off to Mr injector. Bad unit and needed to be replaced. 3 others serviced and cleaned up really good.

Got a brand new bosch injector and installed, then a bunch of backfiring. Found out it was the new injector and sent that baby off to mr injector with some CIS injectors I needed to be serviced.

WOW, 45% loss in that brand new injector. Not sure if it was shit in the fuel system or a bad injector. Anyways they fixed it up as good as new. Got a nice chart of before and after, quick service and 3 jolly ranchers and a thanks for being a repeat customer. Its nice when they think enough to remember you.

My advice, if you can get a used injector at a good price, send it off to mr injector, with the others. After 40 years, the QC isn't there anymore for the brand new stuff.
