Red face Leaky injector - Yes I searched

Ok, so I search the historical documents and have an injector leak question still.

Injector closest to the front is leaking from the bottom seal closest to the cam housing.

..I changed all seals 2 months ago.

Did I just not do that one properly or is the hold-down bracket possibly bent....

Happen to you before?
Think I just need to remove and recheck the seals?
Any other Ideas?



BTW- fuel leaks only when the rail is pressurized and only slightly..
BTWBTW- not driving until fixed

Could be a bad seal, or the injector was not seated all the way in.

Fortunately, seals are cheap - something like $5 each

I have an extra seal kit...will pull and try.

Not seated all the way is what I am thinking but that injector is right at the end of the rail where it connects to the head....thats why I am thinking I might have slightly bent something..

Maybe I will remove the rail and try reseating it first.

Thanks

Make sure and lube the o-rings (i use some ATF) so they don't get cut-up when slipping into the manifold & fuel rail.

There is no fuel pressure at the injector seal into the intake manifold. As far as the intake seal is concerned you can use an old rubber band if it seals off the vacuum.

If there is any evidence of fuel on the outer part of the injector AND it can not be traced back to the upper seal; the injector has ruptured. Replace it.

Not so for the upper seal. This sees all of the fuel rail pressure. Use compressed air to blow off the injector to see where the fuel is coming from.

Most fuel rail leaks can be traced to a fracture at the mounting bracket welds.
