I got everything put back together and finally fired it up (after intake manifold reinstall.. )

I have at least 2 injectors that are leaking.. #6 so much that the fuel drips and puddles quickly on the garage floor.

What o-rings or seals or bushings do I need? I don't want to have to wait for parts from overseas..

I searched multiple words and the only answer I can up with in the whole thing was SOHC KA o-rings work.. but there was some disagreement over it. I also read the entire replacement part thread and found no mention of injector seals or o-rings..

Anybody know?

Thanks!!

If you dont buy from a dealership, make sure that any seal or oring that comes into contact with fuel is made of Viton and not rubber. Viton will not break down when in contact with fuel like rubber does. This is what the OEM o-rings are made of.
