Fuel Leaks

[Dion Ricketts]

Replaced the headgasket and turbo on my car last weekend, but now I have a fuel leak I can't find.

I can smell it pretty well, seems like it is coming from the tb end of the rail, and once I heard a slow hissing sound from that end with the engine off.

Pulled the rail and injectors expecting to find a leaking injector, but couldn't pick out any one that looked like it was leaking, so I replaced the o-rings and put them back in. Still smell it.

Is it possible that the rail has a crack? Maybe the dampener on the end? I have felt and looked all over the place, but I can't find anything wet with gas.

Anybody got any ideas? Rather not look at my car with a black windsheild because it caught on fire.

If you can't find it, I would replace the rail with another and see if the problem disappears. The rails for the 1piece manifolds are fairly common in junkyards.

I've had the rail for the 2piece on my Shelby Lancer repaired 3 times now. Each time it cracked at the fuel inlet tube/rail joint. I've not had a problem with the 1 piece rail on my Shadow.

One interesting thing I noticed on a '90 turbo Caravan in the yard recently was that the rail had no dampener at all. Just a plug at the end and it looked totally stock. If your dampener went bad, you could probably just plug it.

I think I have traced it to an injector. One finally looked clean on one side, plus the manifold looked the wettest around that area, so I replaced it. Didn't have any leaks when I got back, but second gear scratch sure was fun.

Just thought I would update anybody wondering. From what I can tell, the rail wasn't the problem.
