So, I am going to have the Microtech wired in the next few days here. I also, have an S4 mechanical OMP, but I dont know what I should do with the vacc lines that come off the oil injectors. I have no emmissions left, so all those hard vacc lines that are under the manifolds are going to be removed.

Should I just leave the oil injector vacc nipples to atmosphere? Or should I put some silicone lines on there and hook them to a breather? What are my potions?

Eliminate them .I've been running without the vacuum lines for years.I don't even think they really do anything,just put vacuum cutoff nipples on to cover the holes.

The oil injector air bleeds need to be hooked up to the intake between the throttle body and the AFM.

Eliminating them is stupied as the oil gets sucked into the engine faster and atomizes better with them.

Without air bleeds or the air bleeds capped off, the oil just dribbles in, instead of getting sucked and spray'd in.

The MicroTech install should not interfere with the S4's OMP system at all. There are no hard lines associated with the OMP air lines, and the existing rubber lines should be left in place exactly as they are. They are there make the oil injection system work more effectively. If you leave the oil nozzle air nipples open-vented you'll be sucking unfiltered and unmetered air into the engine. If you block them off you're reduce the effectiveness of the OMP system as Mark said.

So what you're saying is you don't actually know how this system works, in which case you shouldn't be posting advice on it. The air lines were not put there for decoration. If you don't know, please don't post.

And some people wonder why others blow motors???

Another example of why the air bleeds are needed, is to get a compressor, air hose and nozzle, a straw and a can of coke.

Put the straw in the can, shoot air from the air hose/compressor/nozzle across the tip of the straw (at about a 90-75* angle).

Watch how coke gets sucked up the straw and if the straw is small enough, you'll actually get coke to spray out.

Its sad that they must not even teach basic science anymore in the US.

just leave it as it is, its only one line on the uim, its even in the back so you cant see it.
