Help, Series 1.5 Top End Rattle

[33GTT]

Hey Guys, have my sister in laws 95 RB25Det, developed a noisy lifter, and by the time she got home, the whole top end was rattling.

Car is auto, completely stock, and never sees the blow off opening at all...

I had a listen and determined that there is minimal oil pressure if any, to the top of the motor.

Oil pressure gauge is fine.

Ran a flush through it, changed the oil and filter, still the same.

Fairly sure there is some sort of blockage.

Question, can the blockage be cleared without stripping the engine, maybe removing the cams and blowing back through the oil passages?

Or is there another problem that is causing this, and I am way off base?

thoughts?

Cheers
