My oil pressure sending unit has failed and it looks like I'm going to have to remove the intake manifold to replace it. Despite what some YouTube videos claim that the sending unit can be changed without removing the manifold I just can't see it, let alone access it. After doing much research I've decided to remove the manifold since it doesn't seem to difficult....and I was going to give the throttle body a good cleaning while I have it all off.
My question; do the manifold gaskets and air intake gasket/seal need to be replaced? The car has 40K miles on it now. I suspect they do or should be replaced, is that right?
They are not much money. The intake manifold job is fairly easy and you do get to clean up a lot of stuff. Be very careful around plastic things such as the evap line. It tends to be very brittle.
I have reused both gaskets myself before. The first time I removed the intake was in 2014 and I replaced all the gaskets. I had to remove the manifold since and reused all the gaskets with out any problems. If yours has not been replaced I would change them due to the age of the gaskets. Good luck and be sure and use a torque wrench when installing your new sending unit. Good luck with your repair.
They are generally reusable, just depends on how flat they are. Takes a visual inspection and not just a blind go for it. If experience is limited by all means, replace them. They're not that expensive as mentioned.
Give your intake a good cleaning when you get it off, My car had around 7,000 miles when I did mine & installed my catch can, I was shocked at the amount of oil that was in & around the intake with such low mileage.

they look good. as long as they are raised higher then the manifold and their is no dry rot and still elastic there fine. But like people said' change if it amkes you feel better.
Prior to removal, get in and around as best you can with a vacuum cleaner and small nozzle. Sand tends to collect near the intake ports and can drop into the head while removing the intake. I would replace all gaskets due to age. Don't forget a couple of slit rubber hoses to hold up the back two bolts.
