Another reason for low oil pressure is simply just oil leaking down on the oil sensor pressure relay wires. Spray the sensor with a lot of CRC electronic cleaner first before going to the trouble of removing the sensor if the wiring connected to the sensor is dirty or oily. Put a little tray under the car to catch the greasy spray as it drips off the engine. If the oil light goes off after spraying then you know it was just a greasy sensor contact and drive on. Note: I used a can of spray since the sensor was behind a pulley and difficult to view and let the car sit over night. Your light will probably come back on when oil leaks back on to the sensor wires and block signals again but this alone will not damage the engine.
Great video! I laughed for 10 minutes with the kerosene on electric connectors trick 😂 please for the love of God use electronic cleaner spray ... It's just safer and less chance of the Chevy catching fire 🔥 afterwards 🤣 Great video though and thank you for your time
I also used a 3/8" stubby ratchet (4") long. I crawled into engine compartment, put my hand/arm to the back, unplugged electrical wire. Removed sensor, installed new one. I did NOT take anything apart. BTW I am 74 years young...
my 1999 astro van has 12 1/2 pounds oil pressure when it is warmed up sitting still. i put seafoam in and drove it maybe 50 miles with whole can of seafoam in it the filter was heavy when i removed it still same readings. i used a oil pressure test kit and that 12 1/2 pounds shows 10 pounds after warming up
Quick note... use teflon thread sealant when putting the new switch in. The red substance on the threads out of the box is a thread lubricant; you still need to use sealant. A leak at that spot on the back of the engine is an annoying pain in the arse.
My 2000 Blazer 2dr Ls is having low oil pressure has about 171k just did oil change and has 33miles on it and ima replace the oil sensor soon, i did run seafoam in oil for 150 miles before oil change but didint do anything but also I notice it only dropped when I come to a complete stop and whenever it’s hot asf like today 93 degrees Killeen tx…I’ve got a 2002 S10 3dr 2.2L with 186k and it’s oil pressure like 60psi+ cold but I’ve noticed with a fram filter it’s lower
I have same problem when mine gets hot or after drive for like 30 miles the pressure oil drops to 23 pounds when driving is almost 60 pounds i been thinking is probably the oil pump i have a 98 s10
Am I missing something? It didn't look like the switch fixed the problem. The pressure still dropped when you took your foot off the throttle. My engine is doing the very same thing. If this is not the fix do you have any more ideas on what it could be?
So guys I'm having the exact same issue with my 5.7 c1500 I've researched there's a filter under that switch that gums up any body try locating that filter? This is my next move because now I have a tapping in a rockers that's not dumping oils like the rest???
Seafom does not recommend "dumping the whole thing in there for half an hour at idle. They specifically recommend 1 oz of Seafoam per quart of engine oil for 150 to 450 Kilometers (100 mile to 300 mile) so that their product can actually work. Dumping in 3 times as much at idle only only lowers oil viscosity and does not allow the product time to work
I have the same issue on a 93 k1500 and the sender did not fix my issue. My needle drops really fast like yours at idle. Could it be the dash gauge itself? I had to pull my distributor to get mine out. What a pain!
I have the same usually in chevy astro 1996 ( the intake manifold gasket fail and the coolant water got inside the engine) I’ve changed the oil twice, but the issue remains. I’ll try to flush the system, maybe it would solve it.
There is a filter under the oil pressure sensor that did not get changed! They are a bitch to get out. But those get gummed up and will cause the issue!
Good job Tony. Love it when people share their work, honestly. Appreciate it!

My 04 Astro stays at 20 instead of 40 has 4.3 v6 and idk what to do it’s slow shifting as well I’m at my ends with it

No sorry

did you find a solution for this so far?
I had the same question
@@mrjcoop17 are you having a similar problem?
@@georgeyoung613 yea I think it’s a wiring problem. I’m not 100% sure just yet but I’m thinking that’s the issue

How were you able to reach over that far? Mine is also at stock height but can’t really reach over that far in the engine bay 😭

So was it the oil pressure switch?

What is it called? Do you have a part number for it? I'd like to see a picture of it. I'm having a low-pressure issue. 1996 2.2 S10.
Good video, thank you!!
i feel like thats still really low and was dropping again but you turned it off before it dropped
I thought the very same thing. This didn't look like a fix at all. I am having the same problem and this video doesn't show a fix.
You're pressure was still low
It definitely was low. That switch didn't fix anything.
