Oil pressure.

I haven`t measured anything acurately, because it`s still in the car. thats why I`am asking if there is any other things to check "superphichially" before renoving the engine.

I can try a mech gauge on it. how do you do that? do you put a mech gauge direct to the engine block or do you use a hose or a pipe to a mech gauge, then check , or just a different gauge and and connect the same "display" in the car?
