Hello,

Has any body installed a new oil pressure sender unit in their c5 without removing the intake manifold? I found this link to a video on how to do so...

I just recently purchased my 98 vert and had no oil pressure issues. Today I was driving around town and noticed my oil pressure gauge was reading 80psi. I'm guessing this is the infamous "oil pressure sending unit problem" I had read about before buying my C5. I'm hoping to put the new one in without having to remove the manifold.... Any advice?

yep, read all of the other posts on the same subject where a bunch of other people have been able to change it using that video. Some just opt to cut a round hole in the cowl so they can go straight in. others use the video. many have found that using the video method takes longer than taking off the intake.

Thanks for posting the "youtube" video....its about a year old but very good. As said before, there are three methods that gets the job done....... 1. The youtube video.
2. Cut a hole. 3. Remove the intake manifold. Its your pick.

I need to change my AIR check valve (in the same area as the OPS) and was considering trying to do it without removal of the intake. But, I have now decided to do it properly and remove the intake. It will allow for me to clean up the area underneath the intake and check things out including the OPS and Cam position sensor.

In my opinion, I think you should remove the intake and do it properly. I cannot fathom cutting a hole in the cowl. It just does not feel right to me.

Remove the intake and do it the conventional way. It's not that hard!

True remove intake and clean behind engine with a good degreaser and dont forget to clean sensor connectors with a electrical cleaner.

I spent an entire afternoon in 23 degree weather trying to get the OPS unit out without removing the manifold. The next morning I pulled the manifold in 20 minutes. What I would do if I could get that afternoon back...

Good job I took about an 1 to remove and install the intake.

Everyone's looking for an easy way to do this, removing the manifold IS the easy way.

What year is your car? I got all excited when I saw this video, but mine (2000 LS1 Coupe) had hard tubes running across the top of the engine at the rear, blocking the socket wrench access. Did you remove those tubes/hoses?

Is there an instruction somewhere that shows step by step how to remove the intake manifold ?

Do the gaskets need to be replaced, or can you reuse them when removing intake?

lionelhutz

If the gaskets look OK then you can usually re-use them.

The first time is the worst. The next time you do it you'll know exactly what, and what not, to do. My first time took about an hour, but I know that if and when I have to replace mine again I can do the entire job in under ten minutes. Little tips like putting some duct tape on the inside of the socket to make a tight fit on the sending unit aren't in the video. I also had hell trying to put the PCV hose that comes apart behind the intake back together. I had to take it apart so I could get my big hands behind the intake to fish out the bad sending unit after it fell out of the socket. All these little things add up to a lot of time, but you know what to do to avoid them the next time so it should be a snap.

removing the intake is definitely the easy way to replace the sensor.

I'm about to just remove the intake. I've learned over the years that it's worth it to take more stuff apart to make it easier than to struggle over trying to get into tight spaces and cussing up a storm.

That being said, any other input about replacing the gasket? How do you know if it's ok to reuse it?

Thanks.

The intake manifold has a rubber gasket for each port. These gaskets can be reused if you've infected them to ensure they aren't damaged or deformed.

Ok, just pulled the intake. Pretty easy, but I had to go buy the fuel line disconnect kit. $10 for really cheap plastic kind of ticked me off.

I've got a 03 with 112k miles. There was quite a bit of oily gunk in going toward the valves. Is this normal for 11 years, 112k miles?

what's the best way to clean the intake while I have it it? Just carb cleaner?
