Once I had the valve covers off it only took about 4 hours to remove the cups, clean the holes, and reinstall the cups. It's probably a 6 hour job total to swap the parts, but make sure you let the adhesive cure for at least 24 hours. Mine took a week since I had to wait on the new valve cover gasket and harness.

good advise for sure.. if it got missed or happened during installation could some emery cloth be sure to smooth it or just use a round screwdriver barrel over it to remove burr.

Probably too late for most of your new cups now, but before putting them in check the top edge of the cups. Make sure that edge is SMOOTH. When I was installing mine I noticed one - near the end - that caught my finger when I was handling it. A sharp edge there could damage a new injector o-ring when you install it.

Did you use a detergent to flush the fuel or just water? If just water, I'd expect the fuel to keep rising to the top for a while. Sucking it off the top is the easiest thing to do at this point. (and possibly easier than dealing with flushing with a detergent and then trying to get all the soap out of the system by flushing again, and again, and again).

I flushed with some mean green, and then about 2 an hour of non stop flushing with a garden hose through the t fitting with no thermostat. I guess I should have done it longer!

I flushed mine at least 6 times with dishwashing machine detergent (Cascade) and at least that many hot distilled water flushes. After seeing what the diesel did to the degas bottle cap I wanted to be sure to get all the diesel out.

I'll keep sucking it off the top until it stops and then flush it again. I drove it hard today and didn't get any more diesel on the top yet.

The good news is the whole oil floats on water thing. I'd just keep driving and checking the reservoir and suck off diesel as needed. Flushing again after you've already got most of it out sounds like a waste of time and money.

Just be sure to check on a regular basis when the engine is cold and has had time to settle till you get all the fuel out of there.
