How Does The Oil Feed Work?

[Gameboy]

Im curious about how the oil feed for the turbo and the VCT work? does the engine pump the oil? or does the turbo and VCT draw the oil somehow?

The only supply of oil pressure (and hence flow) is the oil pump running off the crank.

You should be more curious how the actual engine works before you start wondering about other things.

I already know how an engine works.

It's a bit worrying though that you asked the question that you did. The VCT solenoid is an electric valve that opens or closes to allow the oil pressure to make the actuator turn (when on) or spring return (when off). The oil is a hydraulic power supply. As such, wondering if the VCT somehow "draws" the oil to it is a bit.....um.....strange.

The turbo has oil primarily to float the bearing (assuming sleeve bearing), which is no different to the main bearings in the engine, receiving oil under pressure to keep the hydrodynamic bearings floating so they don't gall up and seize. Even if the turbo is ball bearing, the oil is still supplied (and therefore pushed through the bearing) with the intention to lubricate (and cool) the bearing. Again, wondering if the turbo somehow sucks the oil from the sump is a bit strange.

same guy who asked if he could run a parallel twin turbo set up on an rb26...

ease up geezers...nothing wrong with asking a question or putting forward an idea outside of the box, even if theory is flawed.
