Clearing oil from cylinders after injector R&R

Big Bore (sorry man I can’t remember your name as it’s been YEARS! Frank is it?), do it how you’ve always done it!! So long as there’s oil in the bottom of the engine to lube the rotating assembly, you won’t have an issue. There is NO compression in any cylinders, so even though Berman has apparently reverted back to his dipwad days, it won’t cause issues with the vavletrain at all!

Throw a few bolts into each VC, keep the 42 pin connector unplugged so the idm isn’t commanding fuel injection, and bump the starter several times. Pull covers, clean up any messes as oil drips off them, reinstall what’s left, and change the oil for good measure since it now has raw fuel in it from the injector swap, then go drive the piss out of it to get the air out of the system!

If I’ve done one 7.3 injector swap this way, I’ve done 30 (maybe more) over the years. Never once have I (and likely hundreds of other people) EVER had a problem only bumping the starter to evacuate the cylinders.

Yea man, it's been a few years, you got it right.

I've done it that way several times with no issues but I'm also aware I might have been lucky lol, and I just can't afford to break things right now due to tight schedule and a long road trip ahead so I guess I'm more nervous about things like this than I used to be. I don't mind taking a little extra time to roll it by hand a few times, cheap insurance.

Better safe than sorry..

Ine of those brake bleeder canisters work great also. Just stick the tube down into it and shake it around a bit so it doesn't just seal to the top of the piston then put vc on and bump starter. Im to broken in my old age to do much Armstrong chit anymore so i find easier ways to do stuff. Might take longer but thats my life now.

Look at it this way, take a full bottle of Dawn dish soap, open the lid and turn it on its side and squeeze it. Soap will flow out the tip. Now, take the same bottle and quickly stomp on it and note the carnage. The soap bottle is your engine. Hydrostatic pressure can be devastating if it happens where it shouldn't.

I think this is being way over thought.

Imo if you remove the 1/8th inch allen plugs under the valve covers, let the oil rail drain like you're supposed to, and then remove the injectors, you don't get that much oil/ fuel in the cylinders. I have replaced at least hundreds if not thousands of heui injectors, and have not had a direct or indirect issue afterwards from cranking the engine with gp's removed and 42 pin connector disconnected.
