I have checked the boards and not really found enough info.

My oil pressure gauge when the car is idleing is usually almost to the last mark ( i think thats 60 psi?) and whenever i give the car any type of gas, the needle gets burried. can somone tell me how to check if the guage is correct? and what i should do abuot it?

 

Mine does this too but this is because I have a fresh motor. My old 305 with the good ol spun bearing had 20 psi cold and none when hot. Sounded pretty too *CLUNK*CLUNK*CLUNK*CLUNK*

 

Whoops, forgot to answer your question... not sure. You could try hooking up a manual gauge to test how correct it is. There is a NPT port by the oil filter that you could tap in to.

 

Sounds like your sending unti has decided to retire.

You can either go out and buy a mechanical gauge, and go to all the hassle of hooking it up, and discover that your sending unit is bad, then gpo buy a sending unit and replace it; or just jump directly to buying the sending unit, and be done with it.

 

how much work is involved with replacing the sending unit?
is it expensive?

 

The sender is like $16 and located above your oil filter

 

Are you sure that the unit just above the oil filter is the sender and not the sensor for the fuel pump relay?
If I recall correctly, the sender is Right next to your distributor. Shouldnt be difficult to swap out either.

 

one by the dizzy is the cutoff....one by the O/F is for the guage...If you dont believe me do a search.

 

Alrighty...Was the other way around on my TBI Firebird....Guess they switched it up for the TPI setup? Well, thats good to know.

 

so if my sending unit is bad that just means that my gauge was wrong? and this fixes the gauge? and i don't have to worry about my engine having been damaged from high oil pressure?
