Oil pressure

Post by Initial Z » Sun Mar 31, 2013 2:37 pm

Hey fellas,
Have encountered yet another issue, my fairlady now is running stupidly
Low oil pressure, 20psi if I hold about 2200rpm but almost 0 at idle,
This is at colder than normal operating temp.
I thought the oem gauge and sendor was at fault so I
Imediately replaced it with aftermarket item but got similar readings.
I even tried running a thicker viscosity oil with no improvement.
Now Ive noticed the tappets slowly geting louder, which is obviously
Not a good sign. Any help would be appreciated.
Also if its oil pump issue any tips in regards to replacing it
Would be golden. Cheers

Turned out to be a small dint in the oil pan, unfortunately it was exactly were the pickup hole is,
these things have small square pickup holes in the bottom of a bell with the pickup screen inside.
unfortunatley for me it had to be in that exact same place so a small dint caused a huge headache.
Long story short my oil pan looks brand new, and my engine is happy again.
