[QUOTE="6.0 Tech, post: 1328557, member: 23001"] It would not allow air in per say, but would allow pressure to drop, and if it was in the first stages of failing, would have an inconsistent pressure drop. My truck was doing yhis prior to putting my new injectors in, had lowish pressure that would drop to 45ish psi with an air dog 2. It was also dumping some black smoke on a neutral run up in a stock tune. When i tore it apart, found #5 injector had started burnng the white o ring, bottom section was pretty black, copper washer was ok. No noticeable fuel in the oil, no overfilling of oil. Just suggesting it from past experience as all other options have been about exhausted. [/QUOTE]
