Oil Pressure Sensor Stuck?!

[amylynbubbles]

So I finally got my oil pressure socket on and the thing won't budge. I sprayed a little wd40 on it. Was gonna try using a breaker bar for more leverage, but I'm afraid if I crank it too hard it will break. Any suggestions?

I don't know how you guys do it... I have normal size girl hands and had a b**ch of a time getting to the sensor.

TIA

I went from the top, and used a ratchet that has a swivel type head, like pictured below.

you need a cheater bar, like a 12" piece of galvanized pipe that will fit over the end of your ratchet handle

If all else fails, pulling the intake manifold was easier than I thought it would be. The only real trick is to bleed the pressure off the fuel rail using the Schrader valve before trying to disconnect the fuel line.

Having girl-sized hands is a definite plus for getting it out without needing to pull the intake though. The only reason I needed to pull it is because my hands are grizzly bear sized.

Righty Tighty, Lefty Loosey!

Good thing you don't have man hands!

Got it off! But now... There was no filter attached to the sensor. I'm thinking it's stuck in there. Found a video where a guy used a M8 1.25 x 50 to screw in and remove filter. Tried that... Bolt just spins. I think if I remember correctly his vehicle was a Suburban. I have a 2007 Tahoe LS 4.8 if that helps.

I also saw a video where a guy used a little hook... But worried about effin up the filter or the threads.

Is it possible there is/was no filter. The car was pre-owned?

I used the screw method to remove mine. I did have to press down pretty good while Turing the screw to get it to thread into the screen. If you're replacing the screen don't worry about damaging it.

Also, for some reason I thought the screen was introduced after the AFM systems (V8 to V4 mode) came out. Does yours have AFM? If not, it may not have a screen.

EDIT: attached pic of filter. The framing is made of hard plastic, so when using a bolt into the top of it, you are actually creating threads into the plastic for it to bite into.

No AFM=no filter, if memory serves me right.

 

[amylynbubbles]

First off.... Thank you everyone for all the help! Really appreciated!

So after looking up what AFM is , I found this video:

How to tell if your LS has AFM (Active Fuel Management) - YouTube

Looking at my engine looks like I don't have AFM? See pic below.

Just gonna keep trying.

Definitely wasn't putting enough pressure to thread plastic... Thanks for the explanation. Will just order new screen if I eff this one up.

 

[amylynbubbles]

Wait...I'm a idiot. Filter only WITH AFM. Awesomeness. Now I gotta get the articulating adapter I dropped down there somewhere.

 

[amylynbubbles]

OMG! Could not find my 3/8 articulating adapter so I made 3/8 to 1/2 to 1/2 articulating to 1/2 to 3/8 monstrosity. Got sensor on and then couldn't get sensor socket off. Loosened... Got both off and guess what happened? Yup... Sensor fell down somewhere into the pit of despair. At least it's with it's friends... My 3/8 articulating and a dental pick. I think I'm done for the day. Follow me for more DIY "what not to do".

 

[Fubar0715]

I lost an extension when I did mine....I know it doesnt apply in your case, but I used a pick to get my screen/filter out...FWIW, took me the better part of 3 hours and at least that many beers to remove and replace....Dont get me started on the swearing!!!!!

For those unfortunate enough to have dropped their oil pressure sensor into the abyss... Where did you end up finding it?

Loving it!!
Your journey is Awesome!!
Had work done on mine,dufus mechanic didnt do the distributor back up and i found that out by chance. Lost a 1/2" in my case 13mm ring spanner in what i now refer to as the bermuda triangle never to be seen again
Maybe it will fall out onto the garage floor next time I'm under it!
What are the chances?
Where do these things go!,

I have never found tools that get dropped down there, you could try driving forward and slamming on the brakes and see if anything falls out or gets ejected.

They're hanging out with all the 10 mm sockets that get lost.

That never happens either.
Or trying to drive around listenig for that spanner sound as it hits the road and bounces!

 

[amylynbubbles]

So now....

Who has oil pressure? This girl has oil pressure!!! I effin did it guys! I'm so damn proud of myself.

So you may ask how did I accomplish this seemingly impossible feat... How did I find what was thought lost forever.... I got a $20 bendable camera off Amazon. Hooked it up to my phone... Snaked it down into the abyss and viola!

Guess where the sensor was? Right effin next to where it needed to go. Also got my dental pick. Didn't see the 3/8... But 2 out of 3 is good for me.

Thank you thank you thank you for all your help.

Lol, that looks like when I did mine last year.....
