This hose is plumbed to a small header from all 4 injectors, then where? What does this connect to? Since the nozzles have a built in check valve air can only go one in. Common sense would dictate that you would want air pressure to mix with the oil much like a paint gun, but from what source? This engine originally didn't have a turbo, so that was not the source. None of my manuals is much help, however in one drawing in a factory book that I have there is a drawing of the emissions system, that would seem to indicate they are connected to the dynamic chamber? I'm trying to determine how to plumb this hose and right now the best idea I have is the turbo side of the throttle plate. Anybody with one in their car want to go out and take a look? Using the great new archive feature I looked for some info on these injectors and found that the later models only use the injectors on the housings. Is there an increased flow through these injectors to compensate? I want to use these, but would rather not use the ones on the manifold. I actually cut off the old injector bosses off the stock manifold and welded them to my homemade manifold as ports for MAP sensing lines for my EC2, but they are in a good position to be used for the oil nozzles and I can easily tap in another place for my MAP sensing lines, but I'd rather not. Any idea whether I can simply skip using the manifold injectors and rely solely on the housing injectors? S.
