neohic Posted September 17, 2011 Share Posted September 17, 2011 Question: does anyone know any special or magical wizard way of seating the fuel injector o-rings? I've been fighting this for the past couple weeks and am stuck scratching my head. From what I've tried, the leaks have been around injectors #1,3, and 4. Upon installing, #1 o-ring was damaged twice but has since stopped leaking on attempt number three. The other two are the ones that really have me puzzled as they have been the worst of the three. I took the fuel rail apart again today to find that #4 was damaged and barely leaking, and #3 was not damaged at all but was was very much leaking. I should note that everytime that I put the fuel rail back together, I use a little petroleum jelly on the o-rings with hopes of not tearing them. Rather than going through more o-rings, I'm hoping that some one can help me out. Thanks everyone! Link to comment Share on other sites More sharing options...
wallisek Posted September 17, 2011 Share Posted September 17, 2011 I don't know about petroleum jelly, but I always use a very small amount of clean motor to lubricate the o-rings before I install them. Link to comment Share on other sites More sharing options...
neohic Posted September 18, 2011 Author Share Posted September 18, 2011 Anoher day... another attempt. I gotta say that a little oil worked a bit better than the petroleum jelly, but I've still got a leak on #3. Perhaps this is time to take a look at swapping on another fuel rail? I took a long look at it while it was apart and everything looked fine. :hmm: Link to comment Share on other sites More sharing options...

lexluthier72 Posted September 19, 2011 Share Posted September 19, 2011 hairline crack in the fuel rail? mis-shaped/damaged o-ring? Thats all I got. Link to comment Share on other sites More sharing options...
banshee Posted September 19, 2011 Share Posted September 19, 2011 I just went thru the same thing, same cylinder, new O-rings, removed and used green scratch pad to clean everything, put back together using vacuum grease, and all good... Note I replaced every one, only do it once I always say… good luck... B... Link to comment Share on other sites More sharing options...
