  1. Injector question

    General Discussion
    Should there be oil on the glow plugs and injectors when I pull them? I was doing a compression test today, all minus 2 that the glow plug head broke are at 350, and I noticed oil when I pulled the glow plug and an injector. Is that normal? This all started because I had a huge leak of oil...
