Under Installation Procedure (first item)
IMPORTANT: DO NOT reuse the intake manifold gaskets. Install NEW intake manifold gaskets.

Same issues with high oil pressure readings
I had my oil pressure gauge max out after an oil change. I spent nearly $500 to have the dealer replace the oil pressure sensor. It worked for a while with lower then usual pressure. It used to run anywhere from 40 to 60 psi, but once replaced, it ran anywhere from 18 to 28 psi. The next thing I know (and this was within a month), the gauge is maxed out again. So I drove the car back to the dealer to find out what was going on. I was told that the sensor must be replaced again because of a possible defect. The dealer had a similiar problem with a Tahoe recently and they were sure it may be my problem. I left my car there for the day. I received a call the following day from the dealer and I was told that it must be something electrical, and for another $200 They can run a check on it. I was upset with them to say the least, so I picked up my car without paying them another $200. I feel that I wasted $500 for nothing, so why should I pay them anymore money? Shouldn't the dealer fix it right if the car wasn't fixed correctly the first time? And being a Chevy dealer, don't you think that they should have checked the codes or anything else along those lines?

I hate to bump up an old post, but I believe my sender unit just went kapoot. Anyone know of a good detailed guide on how I can replace it myself? I don't have many tools, and don't have the ***** to take out the intake manifold
