Replaced the oil pressure sensor, Again! Pics!
As everyone has been aware, these GM sensors aren't too good. I installed the last one about 3 mo's ago and it failed 2 days ago. Since I bought it from Fred Beans, I had the part replaced at the local dealership free of charge as the part is under warranty. The first time I replaced it 3 mo's ago, I noted my old original sensor was made of heavy brass. The new one seems like aluminum as you see below and as others have mentioned as well. Seems GM outsourced their parts production in Mexico. Definitely a drop in quality on this particular part given the number of complaints we've seen.
Oh, and I should add I used the recommended torque of 15 ft-lbs to be accurate. I'm hoping this one lasts longer. If it fails, I'll have to throw out some more $$ to buy a different brand instead.
And yes, it was lots more fun the 2nd time around!! I'm getting good and fast at this too.
For those interested, I took a pic of that weany vacuum tube (i.e. straw) in the back that always is a pain to get it to fit into that tiny rubber elbow in the back of the manifold. I took the advice of some others to buy the 1/4 in tubing and a vacutite kit to extend it's reach to easily stick it into the elbow before moving the manifold back into place. Made the install much easier for certain.
Here's a nice step by step w/ pics link for those in need:

Enjoy!
Here's a nice shot w/o the intake manifold:
This pic demonstrates the vacuum tube "mod" which can otherwise make this job quite painful. I tried but couldn't get the elbow off the manifold either. So this addition of the the rubber tubing to the plastic "straw" really was quite helpful. Hope this helps others.
Here's the new sensor. I should have taken a pic of the defective one, but I forgot Basically it had oil inside the area where the connector wire harness would go.
Lastly, here is a possible explanation for the quality issue w/ this part :

I believe NAPA auto parts makes a sensor that owners have had better results with. The GM sensors are a joke. I can't believe where they put them either. Under the intake manifold? I try to look at the bright side.. At least the oil dipstick is not underneath the intake manifold too

GM is either has the dumbest engineers on their design team or the smartest...
I say the latter.. Their directive was to design in the longest and most expensive repairs for the simplest of issues.
They know the Corvette is a High Performance Sports car and the average idiot with $50K to blow is not going to balk at repair prices when something breaks
Where do I start?
Plastic Head light Gears - Could be made of Cheap Pot metal and would last longer
Clutch Bleeder burried inside the torque tube - Remotely located could eliminate 90% of Dealer fix
Oil Pressure Sensor High failure rate and UNDER the Intake Manifold - Easily accessible could eliminate 90% of Dealer fix.
There are three... Anyone feel free to add anymore?

Yep, the list is goes on. Fortunately we all love our beasts too much to consider anything else! I think even some of us love to fix things just to for the fun of it...even twice like me! This time, I took a moment (actually a couple hours) to clean the throttle body w/ carb cleaner, a little dremel action to smooth out some rough spots. I keep adding to the job a bit just to "spice" it up.

Guys, If you buy an after market oil pressure sender made by Standard Ign. part number PS-308, you wont be having any more problems...no, i dont work for them.....I think i might own the record for the shortest time on a NEW GM sender....23 hrs....installed Sunday at 9:00 am..cranked car Monday at 8:00 am to go to work, pegged in 10 minutes...That was 3rd GM part

Bottom line, is it's still On top of the motor in an inaccessible place..

You have a forum member looking for advice on how to replace the thing, and you can't even tell him where he needs to look.
Thanks for the advice.
BTW -- you don't need to remove the intake manifold to replace it. This has been posted before. Take a look.

Yeah there are a lot more, but I recently got flamed for bring them up. I am very dissapointed in GM's quality and engineering. I was raised a GM brat. Dad worked at the Tech Center from 55 to 85 when he retired. Does that mean I don't like GM products no not at all but the pea poor quality and design explains why the car company I grew up on is fast falling and soon will be number 2 behind Toyota. It just to sad to believe. It is a compnay that for far to long has been run by the bean counters and not by car guys.
