Default Changing oil pressure sender

Does anybody have the pictures or the full process to change the pressure sender via cutting a hole in the cowl under the wipers? I can find the article inC5 tech, presumably it's the same for the C6? but all of the photos are missing and I would really like to see photos.

Thanks

Here is a you tube of the process, without cutting the cowl, but it does remove the intake and associated stuff to get at the sensor.

Why would you cut the cowl?

It can be done without removing the intake and without cutting the cowl. I've done it. It isn't easy and requires some patience and dexterity, but it is doable.

beause that’s the only way I’d seen it done before without removing the manifold, I also have big inflexible hands, lol.

but now seen two videos this one on here where a few hoses were removed, another one that came up straight after in YouTube that took about 10 minutes and didn’t remove anything except the valve cover and the sender.

really does look pretty simple.

yes upon much reviewing I’m going to cut, otherwise I know how it will go, take 10 times as long , I’ll drop something I can’t retrieve and what little skin is left in my knuckles along with the scabs from tidying up the wheel wells, etc will be smeared all over my inlet manifold, lol. At a guess it will take 20 minutes cutting and 10minutes to 5 hours not🤔

It is so easy to just remove the intake. You can have it off in about 10 minutes if you can not get the sensor replaced. Don't cut on your car! You will be happy later that you didn't.

OK son it is very easy. Disconnect you air intake at the throttle body, disconnect spark plug wires at the coil packs, remove the coil pack brackets on both sides leaving the coil packs attached to the bracket, pull free any wire harnesses that are attached to the intake or fuel rail and disconnect those harnesses to allow more room to move them, disconnect the fuel like front the fuel rail. I believe there are 10 bolta in the intake. Remove the first 8 and then loosen the back 2 and pull them up and tape them. These will hit the cowl and can not be fully removed. Taping them up allows you to pull the intake forward. Pull it forward enough to disconnect you vacuum lines in the back of the intake then carefully pull the intake out. I highly recommend taping the intake runners to help prevent dropping anything into the heads. OK so maybe a little longer than 10 minutes but it is definitely less than an hours work to pull for a first timer. Its easy and you get to spend quality time with your car.

It’s easily under 30 mins for a first timer. Literally just a few bolts hold it on, brake booster hose on the back and that’s about it. 4 hours would be robbery even for a dealership.

Thanks for the help so far guys, but I’m still lost on this.

before I start taking things apart I want to identify where it is.

all the pics and videos I can find are for the C5 and therefore LS1. I am looking where I think it should be and all I se is an electrical connection with 2 wires not directly connected to a sender just coupler. Does anybody have a picture of the exact location for the C6 & LS2?

thanks

The top video that I attached in post #2 above is of a C6 LS3, which is in the exact same location of the LS2. Here is a diagram from the service manual for an 6.0 LS2 it is item #18

Although I would never cut the cowl to get access to the oil pressure sender, here is a few pics of someone who did. You can see the top of the sender.

That was a butcher job, I have seen cars with perfect cut out using drill bit you use to cut door **** hole, perfectly round, large enough to slip the socket for R&R of the sending unit.
Then they took the plug, and glued it back into the hole, sealing the hole from which the drill bit cut, and after little touch up hard to see anything was done.

exactly what I used 40mm hole already cut when I took the wipers and cover off, all went well except losing the bloody brake reservoir cap somehow!

and having to make a connector for the three pin connector as the one on the car had fallen to pieces! Guess it isn’t the first time it’s been done

Still totally ridiculous to cut a hole in your car because you don't want to spend 20 mins pulling the intake off. It's a very easy job.

To each their own though, I suppose

but it’s already there, would have been silly not to use it.
