hi all

i have a problem i just bought this car yesterdayall in good codition new radiator new tires new brake and new mainseal and a cam and magnaflows...

so i was driving the cartoday and the motor was cold and the oil pressure was about middle way but after engine started to warm up it droped down to the last line before it hits 0 but if i let off the gas it will go up almost to half way again till i give it a tad bit of gas there is no smoke after start ups cold or hot ......

was woundering if anyone could help me its not leaking anything already been under car to check might be the oil pressure sensor or oil pump ??

ohh and this is my first 1994 z28 lt1 camaro AWSOME AS HELL i still have my old 1994 v6 camaro but tranny is gone

any way thanks all

 

Bad oil pressure gage or sending unit, bad oil pump, low oil. Check the oil pressure with a mechanical test gage.

 

ty man for posting now one more simple ?,,,,, what is this i got circled in the attached pic it goes from air filter box to some metal thingy then to another tube and then to Tbody thank again

 

That isthe MAF (Mass air Flow) sensor. Measures the amount of air the engine ingests. The PCM uses this info to determine engine loadand and adjusts the A/F ratio and spark timing as needed.

 

ahhh so no taking it out lol ok cool im about to go change the oil pressure sendingunit and see if it works thanks man AWSOME forum to

 

lol dont mean to sound stupid but where is the oil pressure sending unit on this z lol on my v6 it right on side of block above the oil filter but the z28 i cant find nowhere

 

did you try changing the oil? if its old and broke down you will see low oil pressure. try changing it out for some mobil 1
