Hi Guys;
On the oil injector nozzles there is a 1/8 hose that connects onto the top
of the nozzle, while the oil enters through the banjo fitting. 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?
