im trying to buy the upper and lower o-rings for the fuel injectors, i suspect they are the cause.

http://www.hondapartsunlimited.com/f...AKE%20MANIFOLD

from the parts diagram i think they are part #

16074-ZY3-000
16472-PH7-003 / 16472-P0H-A01 <~ also why are there 2 part numbers for the bottem o ring?

 

reference numbers 2,3,35 are for each injector. There is one seal ring, one o-ring, and one cushion ring for each injector. The seal ring sits in the intake manifold for the lower part of the injector, the o-ring sits in the fuel rail for the upper part of the injector, and the cushion ring sits under the fuel rail.

I'm not familiar with the way that website works but it seems like they list different o-ring numbers for different manufacturers of the same part. If you want the o-ring the one made by Arai will work fine.

If you are getting leakage out of the fuel rail from the injectors the o-ring is what you need most, if you are getting leakage out of the intake manifold port then the seal ring is needed, but they rarely leak, the cushion rings can be re-used a couple times and dont really cause leaks. THe injectors changed in 06+, make sure that website is isting the parts for your model year.

I prefer to use majestic Honda's website it tends to be simpler to use, they don't list multiple part numbers for the o-ring only one part made by Arai.

 

Thx man ordering now

 

Make sure you "lube" them with oil before you install them.

 

+2, any type of motor oil you have laying around will do.
