..

make sure you have adjusted the overhead valves before the test. Otherwise you could be getting false results.

Also, if you can't find it because it is only a tiny bit leaky and very hard check,.. If it were mine, I would not even bother to change the injector. It is not likely bad enough to cost you fuel mileage yet.

I haven't dug into an injector to see exactly how they work and won't so I don't lose a core haha, other than the fuel system video on youtube, to see what there is to the check valve - but it comes and goes, and generally runs smoother with more consistent fuel mileage while running Amsoil Injector Cleaner. Other times I'll get a valve lash sound, roughness during a pull, and drop 3-5 points in fuel economy for no reason. I'm generally not a fuel additive guy, and it's more of a bandaid on a bullet hole.

The dates and serial numbers on the old injectors were listed on the TSB discussed here a couple of years ago, but when I was putting this thing together, I couldn't justify swinging another $5k at it for new injectors at the time.
