Lost oil pressure, need help!
Okay so i posted this thread a few days ago about the "ticking" problem my car developed.
https://ls1tech.com/forums/lt1-lt4-m...help-asap.html
Well yesterday i went to work on my car some more when all of the sudden I had ZERO oil pressure. Now my car has kinda had a fluctuating oil pressure for the last year where it kinda skips around on the gauge a bit.
So now I think I found the ticking problem. would the oil pump drive gear have gone bad and made that sound? or whatelse could have happened?
I had great oil pressure before even when it was ticking but just yesterday it had absolutely none.
Any help is appreciated!

put a mech. gauge on it and see what the pressure is. If its under 10 psi on cold startup then i would just suck it up and pull the pan from there you can check the pump and drive gear and check the bearings. And drain the oil into a clean jug so you can check it later for metal flakes

Is the oil glittery as checked at the drain plug?
If NOT I might risk another start with a mechanical gauge. If it is glittery then you know things need to come apart and no sense risking further damage with a restart.
Really if the oil at the drain plug looks clean you could disable the injection and see if any oil pressure registers on a mechanical gauge just cranking with the starter.

mech gauge, if you have no pressure then I'd pull the intake and look at your fake distributor that turns the oil pump. it could have came loose, or broke. How many miles?

I agree with Dwayne. It's probably unlikely the gauge is bad at this point. Before you check the pressure with a mechanical gauge I'd strongly consider checking the oil for metal and checking the oil pan to see if the pickup fell off (rap on the bottom of the pan with a mallet to see if it's bouncing around).
No use starting it again potentially causing more damage.

Car runs just as it always has which is flawless, just has a tick now.

I narrowed it down to the #5 cylinder because when it's running, that particular cylinder has more of a high pressure popping action from that primary compared to the other 3. So maybe a burnt valve?

I'll try to snap some pics if I can.

The only things I can think of that would be making that sound are:
Oil pump drive gear
Burnt exhaust valve
possibly my flywheel or clutch (most likely not)
All I know is that it sounds like it's in the drivers head somewhere near #5
Rockers are fine, Pushrods look good, I think Icould tell if a lifter was stuck so I don't f***in know.

Thats what I was hoping it was but I can guarantee you it's not, i've had the header off 3 times and nothing changed. It's for sure somewhere in the valvetrain.

If I have time i'll pull the header back off, but it's the Dynatech gaskets that came with my headers. I don't think it's just a leak cause the car just feels dead when I get on it as if a cylinder is missing slightly. And it had full power the day before when I first put the hearders on.
