I took a closer look, the injectors are not leaking where the 2 halfs unscrew. The return lines are less than a year old and they are not leaking. The very minor leak seems to be coming from the base of the injector where it screws into the head and is on cyl #1 and possibly #3. How do I check the pre chambers?
