Now for the installation
1. Go ahead and first lube up all the injectors, especially around the o-rings liberally before putting them back in. Then go ahead and start putting the injectors in and use a rubber mallet to tap them in the rest of the way to be sure they are seated. Then reinstall the retaining bolts and oil deflectors, and galley plugs.
2. Then before going any further you need to purge the cylinders of any oil to prevent hydro locking. So with nothing else hooked up, hook the batteries back up and crank the engine over with the key a few times. You will see oil coming out of the glow plug holes. Do this until just a mist comes out.
3. Once this is done go ahead and reinstall the glow plugs, preferably new ones.
4. Then hook the UVCHs back up along with the valve cover gaskets and the wiring that runs to them. Also refill the HPOP. Now it is time to get the engine started. You should do it first with the valve covers off to inspect if anything is wrong. Crank for about 15 seconds each time giving it gas then let the starter rest for a minute or so. Dont get scared it took me about 25 minutes to get it going. Once you do let it run for a couple minutes.
5. Once that is done go ahead and put the valve covers and everything else back on
6. Once all that is back on go ahead and start it again and drive it for about 50 miles to get all the air out and be easy on it so you dont risk scoring the tips of the nozzles and enjoy the new injectors!
