10-4 on the immersionI would not immersion clean the injectors unless you put an air tight plug on the return and supply lines. Any contamination inside the injector can destroy it. Personally I would clean externally by hand only.
Also, I would not touch the glow plugs at the same time as the injectors. Get the black good cleaned up, and the injectors back in. Once its running and everything seals. Then you can tackl the glow plugs.
So at this point i am going to pull the keepers in the injectors and start cleaning deeper. I have hand full of plugs I could jam in the hole so nothing sneaks inside . Going to order that Carbon-off product by discovery
I was also planing to do all 5 injectors because that’s is how I do thing unless that is over kill and I only do the one is leaking .. Any thought on that
