I did change out the defi sensor for a new oem sensor - this was one of my first checks along with the level of oil on the dipstick.
The engine temp was coming up and down so I was left with only few options, check the pump which is good and pump checkvalve plus oil squirters ---> which I haven't got to yet and then check rod bearing clearances I still haven't removed the lower block.
as soon as the plasti guage and torque angle attachment arrive I will check the bearings clearances - for now I can only prey that i'll be able to get the correct bearings to bring the clearances back into spec and get some oil pressure.
You don't have to remove the lower block to check rod bearings, lower block comes off for the mains.
So I am doing this right now - I took the first cap off with fingers crossed and to my surprise the bearing and crank looked pretty good
After torqueing the first cap back with some plasti guage I found the clearance to be 0.0015"
Here is a closer inspection the plastiguage squish looks pretty uniform across the surface. I will do them all twice just for good measurements.
My main question at this point is, since the other two bearings/rods are up and it would be nearly impossible to lay plasti guage up inside the block past the lower block (I'm doing this on my back -engine inside the car) would it be ok to rotate the crank once the previously check caps are torqued back to spec (finished the two middle rods that are down)
All four rod bearings are the same 0.0015" clearance according to plastiguage check.
There is a bit of what looks like tiny pitting on the bearings in the lower part of the bearing half, is this normal wear? This bearing measures 0.0015" clearance but I'm abit concerned with the small pitting in the one spot
And now I don't know what to do, Can it be possible that the oil level was just reading incorrectly as I wasn't awair the dipstick reads true value on oneside and incorrect on the other side.. I sure feel a bit like a dipstick myself.

Ideally you should remove the PLASTIGAUGE stripe with a clean oily cloth or industrial de-greasing solvent, but users may be assured that any PLASTIGAUGE left behind is oil soluble and cannot harm the engine in any way.
That's totally normal bearing scuffing, well it's definitely not the rods, nor the pump, with the rods being perfect, I'm guessing the mains will be the same way.
