I am loosing oil pressure. I had a slight* leak at the at the feed line for the turbo and my filter was loose. I tightend those. I was also really low on oil because* of the leak. So i topped it off and at idle pressure* was up to 40 psi and when i tap the pedal it jumped to 80 ish. Took off down the road and mind you the engine was up to temp.fir the first few min it acted* just as it should. Then i started* to push the turbo a bit not up to boost but spooking up and then it would drop. Let off back to 40. Then just cruising it would* bounce up and down to 0 then back to 40-80 depending kn throttle. Then just basic throttle will drop it to 0. Pulled it over. Idle it was 40. Pedal it and jumps to 80.

Could it be a sending unit, debris in the pick up tube, clog in the turbo feed line, or worse a spun bearing.

I have drained the oil and checked the filter yet. I will when i get home.

I am at a loss. And i still have not had a final tune on this.

Hook up a mechanical oil pressure gauge before attempting any oil pressure diagnostics.
