Check Gages- Oil Pressure?

[Chris.G.Jr.]

Alright so i drove down to edmond/okc (2 hour drive) from bville bc i have a dentist appointment monday, well the truck droves normal and perfect. Drove around a bit last night and it was great, wasn't hot rodding it or anything. Well i went out today and drove ti down to bricktown with my buddies and it drove great but when i got down there the CHECK GAGES light would come on everytime id come to a stop. So i was looking at the fuel gauge, the volt gauge, the water temp gauge, and when i looked at the oil pressure gauge it was reading 0 when i was at an idle. I looked in my owners manual and it said to immediately check the oil and dont keep driving if its low bc it could catch the engine on fire. I immediately checked it and it checked out fine. Trucks running great driving great no weird feelings or anything. No weird noises. So i get back in and drive back to my friends and its driving perfectly fine, just the oil pressure gauge drops when i come to a stop, usually when its under throttle it reads about 40-60 (usually between the two closer to 60) well under throttle now it only was reading about 38-40. When i first got the truck a yr and a half ago we had the oil pump replaced and oil has been changed regularly, regular maintenance is kept up with.

I know theres the cable that runs from the speedo to something, but wouldnt there be cables running from each so they properly read right? maybe the cable is loose or something? Just confusing why its acting up when it drives great! The water temp gauge was reading its normal operating temp. the volt gauge was reading normal,and had half a tank of gas or a little over.

Anyone got an idea? i have a dentist appointment tomorrow morning round 8 so after that im gonna run to the shop where they installed my oil pump when it was worked on.

its the sensor acting up. basically there is a sensor on the motor that tells the cluster what oil pressure you have, they go bad over time, either wear out or get clogged up.

hmm how do i replace it? i thought maybe it may be the oil sending unit.....

well guys im in the process of uploading a video of the engine.............i think this is it ..........maybe an excuse to start the supercharged 6.0 build?

it didnt before!!! all i could hear was the exhaust and i didnt hear a knock......

and that was before i had to drive 2 hrs back home.

so heres a pic of the oil pressure when its sitting there idling, usually its at 20 idle 40 at cruising and 60 under throttle.....i have the oil pressure switch but since i heard the knock i havent changed it.....plus its kinda a pita to unscrew it from behind the distributor.

this cant be normal, every now and then the check gages light flashed when the pressure dropped

shit no man.........drove it today to get something to eat and since i have a dumped glasspack i dont really hear much of the engine, i can hear a little knock, but i can kinda feel a little in the gas pedal.....still in the works to getting this old beater truck we have road ready so i can cruise around in that til i can have the truck fixed....

just change the sensor. worst case you wasted a little time, its better to know if you have oil pressure or not.

cant get the fucker unscrewed, id have to take the distributor completely out in order to get the right angle on it and be able to unscrew it

Then I'd get on it. Better to take an extra hour than to have a fucked engine for sure

you dont need to pull it all the way out, just undo the hold down and pull it up enough for clearance.

shit man already know engines fucked bc the knock the switch is just gonna fix the gauge but it aint gonna get rid of the knock
