Oil injector unclogging?
 

Premixing on my S5 NA right now. Replaced the oil injector lines awhile ago, previous owner's "fix" made me extraordinarily angry. Only one of the new lines ever filled completely with oil (used clear small engine fuel line), the other three got a quarter the way to 2/3 they way up. Assuming my OMP isn't malfunctioning, which It may very well be, is there any way to unclog clogged oil injectors. I suspect they're clogged because the previous owner's "fix" left three of the injectors unable to receive oil which sat stagnant and cooked over the course of unkown thousands of miles...and I will not get this engine compression tested out of fear. Starts runs, and roars just fine though.

If I'm not mistaken, S5's have an electric pump on the oil injection. Have you tried to test for voltage to the pump?

Yeah, I'm dropping 11.4v from the positive battery post to the terminal. I'm thinking if the four control wires to the ECU are still good, I'm going to route nee 12v and test the OMP flow.
