my oil pressure guage is acting wacky, it either goes all the way past the highest point or all the way to the bottom, what would case this and what can i do to fix it? would this be controlled by some sending unit? if so where would it be on a 305 84 camaro? thanks

The oil sending unit on a V-8 Chevy is usually on the back of the engine block behind the intake manifold slightly to the left of center. There are two different types. One for the idiot light and one for the gauge. Make sure you get the right replacement. Your problem is either the sending unit or the wiring to the gauge. If the wire on the sending unit shorts to ground the gauge will peg. If there's a break in the wire the gauge will stay at zero.

does this mean there are 2 sending units? or are you saying there is only one on the engine but 2 different types? ill have to check the wiring, the guages are all new so it has to be a bad wire or sending unit.

Assuming it isn't a mechanically driven gauge, (which just has a tube going to the back of the gauge) there is one sender located on your engine. However, there are two different types of senders that this could be, one for a gauge, and one for an idiot light. If you decide to replace the sender, be sure that you get the sender for the gauge application since you have a gauge rather than a dummy light.
