Oil Pressure Dropping On Gauge

[nemo]

Recently i had a oil filter relocation kit fitted to my 32GTR and new oil etc... and now im noticing that the oil pressure is dropping down between 0 and 2 on the pressure gauge but while warming up it sits on 3 to 4 on the gauge but after i finished driving and open the oil cap there is plenty of oil in the head, i was wondering if its dropping because of the extra travel the oil has to make thru the oil lines from the old filter location to the new location

I have an oil relocation kit on my R32 GTR also and my oil pressure gauge runs similar to yours. As others will tell you tho the factory gauge isnt always 100% accurate..

location of the sender and length of the pipes should make no difference - pressure is the same everywhere in the system.

so...either your sender is farked (I hope) or you have real problems. get a mechanic to check it out in case

sorry abit of topic, but should a oil pressure gauge always have the same reading or just it move when off accelerator, when warming up etc

yes the oil pressure should vary. It is normally 2-3 times higher when cold, and since the oil pump is on the crank, when revs increase so does pressure. the actual level depends on your oil, clearances in the motor etc.
