Vacuum leak at injector seals
I just got my 1.8L swap running in the last week or so. I used RX-8 yellow injectors for my build, and noticed a vacuum leak at one of the injector seals to the cylinder head. I sprayed brakeclean at the seal when at idle, and could hear idle speed change, and saw the engine go rich on the Wideband sensor.
I remember when I was assembling the fuel rail - I used brand new (parts store aftermarket) injector seals, and they seemed really loose on the RX-8 injectors. Not exactly hot-dog-in-a-hallway loose, but certainly looser than the stock injectors.
Since I used brand new seals, what should I do to fix this issue? Buy a different brand of seals?? Use rtv during installation? Add a extra O-ring to the stackup?
