What is entailed?  Has anyone done it or seen it done?  Is it as simple as drilling through a web into an existing channel or tube crossing from the oil galley?  Or do you have drill completely through the block?

You would have to drill all of the way through the block. Good luck with that.

You have three options.

1# Use the extra plugged port located under the pass side motor mount.

2# Use the oil pressure gauge port (right next to the pass side motor mount)

3# Follow the rib on the outside of the block from the extra plugged port to the pressure sender. from there follow it up and over to the rear of the block. You will find a flat round spot on the ribbing right past the oil filter. That can be drilled
and tapped for oil post filter.


You can find a bit of info here along with a pic or two    http://www.pirate4x4.com/forum/toyota-truck-4runner/760711-mr-stubs-notebook.html

Thanks.  I found that thread.  I couldn't find anyone who had said definitively whether the turbo oil channel was mostly there or not.  For the last two years, I've been using the boss under the filter.  But that is unfiltered oil, and for some reason I've been losing oil pressure to the turbo on occasion.  It has cause the failure of more than one turbo.
