I got all 4 injectors tested this morning and 3 out 4 need new nozzles. I am ordering new nozzles today. I am still stumped at the leakage which is not where the Injector screws into the head, but actually outside the ring that holds the pre-chamber in. The leakage is occuring at cyl # 3 & # 4. This is also where the two Glow Plugs were burned in half. Interesting that one injector was good and one was bad, when tested this morning. I am going to clean them, replace the nozzles, and heat shields and see what happens. It will be a few days until the parts come. I will update everyone on how it works out.
