Sounds like your o-rings are done! easy to replace, though!

They are leaking from in between the fuel rail and the injector, I assume?

 

[suprakidd]

possibly what would it be if it was leaking from the head? for refference.. thanks a billion.

Umm, there is no fuel that goes through the head. But, I still think it's the O-rings that you are in need of. You will need 6 -orings, and 6 insulators to do the job right (and avoin vacuum leaks)

Look for part numbers 23291 and 23250B

Actual parts are
O-ring- 90301-07001
Insulator- 23291-41010
Get 6 of each!

If you feel the need, take some very good macro pictures of where its leaking and we can try to pinpoint the source, or at least tell you what tests you can to to pinpoint it!

are you sur the injectors dont sit against the head? isnt that where they spray the fuel in??

They dont sit on the head....they are on the IM (intake manifold). To solve your problems take off fuel rail and change out o-rings and insulators. You might have pinched or squeezed the rubber rings or insulator too much or unevenly, thus leaking.

yup thank u guys two of the injector o-rings were smashed. i rplaced them no more leaking for now...
