Hello fellow ponydudes,

I have a question for anyone whos had oild pressure gauge issues, I did a search and came up empty so here it goes.

My dad has a 91 GT , and as of late, the oil pressure gauge has been extremely low and at times has shown a reading of 0!

hes only got about 55k miles on it, and hes 72 years old, the damn thing is cherry. I am curious if it's the actual gauge, or isn't there a sensor somewhere in between the pump and gauge? Is this a common issue? where can i begin to diagnose this?

the gauge reads only sporadically up to 1 hash mark roughly 17lbs., it doesnt leak and has had no previous problems at all.

any input?

thanks

 

Start by testing the oil pressure with a known to be accurate guage.
If it's a mechanical guage,make sure there's no blockages in the line.
If it's an electrical guage,the sending unit could be bad.

 

its a mechanical gauge , i guess ill start there..thanks..

anyone else?

 

So, it's an aftermarket gauge? Factory gauges are electric...senders go bad. I keep a mechanical gauge ($15 el cheapo) in my box just to troubleshoot such problems.

 

no im mistaken its a stock gauge ..the whole damn car is stock..i just assumed it was mechanical...

 

stock gauges SUCK!

 

I pulled the motor (or had it done) and put in a new high flow oil pump. Still have stock gages and reads in the upper half (barely). I also use Castrol 20-50 and lucas oil treatment (110M) miles.
