Had air leak on 2003 6.0 (early) high pressure oil. Replaced o rings on injectors and oil rail. Checked with air test and have air coming out of the little holes on top of three injectors on left side. Is these injectors bad and should I replace them? Did not look close enough before I replaced the o rings, so am not sure if that is where the leaks were coming from.

Thanks

 

Are you talking about the hole in top where the oil rail plugs into it? if so you can get those Orings too but ou can't get them from the dealer, I got a whole set off of Ebay, they offer them as just the top orings or the whole kit, I got the whole kit and think it was $87 for a set of 8, I needed them quick so I paid $20 extra and had them 1 1/2 days later. they were also made by Alliant who is the original manufacture of these injectors.

 

No replaced those, its the two little holes on each side of the fuel rail hole.
