Oil pressure down to zero, ticking.. HELP!!!

[toofast4yall]

To start I have an 87 gt. Well I have noticed within the last couple days that when im driving my oil pressure guage will drop down to zero at seemingly random times and then bounce back up to normal pressure. I thought that it was just the gauge, but now the motor has started ticking very loud and it is my conclusion that the motor isn't getting oil where it should. Obviously I shouldn't drive it now until i figure this out. It does have oil in it. What needs to be replaced? The sending unit? the pump? any info would be great, I really need to figure this out. Thanks.

Probably in the same boat I am in. I am pulling my motor and putting a stock one back in. Good time for me to upgrade.

Probably the pump, but could be the pump shaft.

Replace the sender first, If that doesn't do it most likely the oil pump is gone. Been there.......

what does the sender actually do? Where is it located? Is the oil pump the one inside the oilpan? Thanks

yes, the oil pump is inside the pan. The sender is on the drivers side front of motor. Almost right next to the oil filter.

try an autometer oil pressure gauge maybe. would cost about the same and be an accurate gauge.

sounds like the oil pump is most likely going out since it is now ticking. not getting oil to the lifters probably. oil pump is not fun to replace.

any info on miles, how its driven, mods? might be a place to start. usually oil pumps dont go out unless the miles are getting high

about 90,000 miles. I belive im the third owner but not sure. I drive the car pretty good, not too much beating on it. The only mods are exhaust and ram air. Otherwise all stock.

Mine went out with about 125k miles on it. Car was raced quite a bit, though.
