Has this been done? I know it's been discussed. Specifically, I would like to use a non vvti 2uz block with 1uz vvti head. 2jz guys use an external oil line with banjo bolt to supply oil to vvti head when using a non vvti block. Is this possible on the 1uz or 2uz? Or shall I say what is the consensus as to best way to achieve it? Oil pressure sending unit? Sandwich plate on oil filter? Or is there a location to tap the block?
