I happened to be checking things under the hood yesterday and saw that one of the 4 oil lines was more clear than the others. Looked like 3 of them had oil in them, and 1 didn't.

I started the engine and worked the pump metering rod to simulate full throttle and I saw the oil rise up towards the injector again. Not sure if this is a problem, but has anyone else seen this happen. I don't like the idea of oil-starving my rotors\\

What, is everyone running premix nowadays so you don't worry about those tube things???

If you saw the oil go up towards the injector then is there a problem. Perhaps the injector failed, in which case I would recommend replacing all of them with banjo bolts from Atkins. They eliminate the vaccum and ensure they always work.

What vacuum are you talking about? (loaded question, beware).

Matlock

The vaccum ontop the injector, used to close them! What's the loaded part? Please fill me in.

HAILERS

There is no vacuum on top of the oil injector. Thats what.

Raymr

OK, any thoughts on my question about the oil draining out of the lines after the car sits overnight?

Matlock

There is no vacuum on top of the oil injector. Thats what. What is? I could swear that mess of **** was connected to vaccum. Is it for looks? Fun? It has some relationship with vaccum. Please elaberote.

Correction: They are air hoses! Problem solved

They're not a source of vac, but a source of pressure.

Its just a source of filtered air and pressure(ambient). Comes from the front of the throttle plates. The vacuum comes FROM the oil injectors. If you think about it, it's indirectly a part of the idle circuit, because its sucking air.. I said indirectly, not its purpose in life.

The same can be said for the single hose that goes b/t the two oil injectors that feed the FUEL injector air bleeds. Not a vacuum hose but just like the oil injector spider, get filtered air from the front of the throttle body.

RAYMUR..... If the oil in that oil injector hose fills up when the engine is running AND the rod to the throttle is pulled up as if you were driving.......I'm not sure I'd worry or do anything. One thing you should take a few minutes to do, is put a hose on top of each injector and blow into it. Air should pass. Then suck on the hose. If it does not hold a vacuum as you suck on it......replace it. Its broke. I understand that if thats the case it will suck much too much oil and cause you to have excess oil consumption.

There is a test in the fsm that is free online.....where you can check out the metering oil pump and amount/flow of oil for each tube. OIL Section I think.

Frankly I don't really know EXACTLY how the oil injectors work. It was explained to me in an old post, but I've never seen it explained in a manual etc. NZCONVERTIBLE is one who could explain it, maybe.
