Intake Gasket??? Help
I read the instructions on replacing My Oil Pressure sending unit. It is under the intake manilold. Instructions on tech tips say to just slide the intake forward about 6 inches. It also says the gasket can be re-used. Is this really OK or should the gasket be replaced? Has anyone done the repair without changing the gasket? Stupid pressure sensor should last more then 65,000 miles anyway. Can't believe it took a dump so soon.

Intake manifold gaskits are actualy individual O-rings around each port and yes as long as there not damaged they can be reused many times over. You may want to replace the sending unit with a after market one as the GM sensor is a POS. I replaced mine with a brand new GM sending unit the first time and two weeks later it was dead, 2nd time around I bought it at NAPA and it's been good ever since

Yes the intake gaskets can be reuse over and over since they are rubber type o-rings. Just inspect them to be sure they are not cut or damaged. But be careful about sliding the intake forward as it can dump lots of dirt down the intake ports in the heads. My advice it to go ahead and pull the intake off so you can clean everything up good. The intakes are easy to pull, only takes a few minutes. You leave all the fuel rails and injectors in place but you will have to remove the fuel line(s) with the special tool but it only cost a few dollars at places like Auto Zone. Better to spend a few extra minutes and make sure you do a good job.

Personally, I would replace them. I would also completely remove the intake. Here's my logic, I just got mine off the other day. First, there is a lot of grit around the intake that just simply blows in there. There will also be some oil, not a pretty site. Second, when you move the intake, this grit and oil is going to get wiped into the gaskets and possibly the intake ports. If it were my car, I would remove, thoroughly clean and then replace the gaskets.

I left my gaskets (o-rings) on. Did not have a problem with lots of trash or oil in the area. I removed the intake and cleaned it up. The gaskets looked fine. I vacuumed the to remove the bit of grit that was near the valley. I wanted to make sure nothing went inside where it was not supposed to. I did not remove my fuel lines, just moved them out of the way. If I had a fuel line tool however, they would have been removed.
