    Good for you.

    It isn't as big of a deal as it is made out to be.

    It is just hard to get at cuz you can't see it.

    I replace em by "feel" now.

    I don't know honestly, I think Dormont is a pretty common manufacturer. I have a buddy that works for PAPA Automotive and he has been giving me stuff at cost for years, so that's where I got mine. Just stay away from KEM, its all junk.

    Are we talking about Dorman? Never heard of Dormont. Dorman (mainly chinese manufacture) is famous for coming to the rescue for either expensive, unavailable or faulty factory parts, just like this. Though my sensor is original at nearly 100k, no funny business. But I should stop saying that because it'll fail the next time I drive the car.

    Thank you. I bought some "universal" Dorman exhaust studs (manifold to cat) a while back but I could not remember the name. Their parts are sold at many part stores and do have an online catalog.

    Old story, but when I installed my maggie I was telling my friend helping me that I hoped I never had to replace that sensor.

    I am on #4. but I can replace those POS in short order now.
    Did you have to shave down the outside of the actual socket Or trip the block? I cant get it to fit between the block and the nut. My Maggie just returned today with install tomorrow morning so I want to knock this out while its right in front of me. Thanks.

    It was a "lip" on the maggie I had to grind down.

    Does your socket package say that its for 4cyl GMs and 3.0l V6s? Mine has the same part number at the top but it definatly doesnt fit in he VERY thin gap

    Re: Oil Pressure Sensor Sender Failure

    Well, after MUCH deliberation and temptation with the Dremel, I have decided to remove the valley floor plate to get to this sensor bolt. That is the actual like that sits right up next to it. I worried about triming off the necessary metal that close to a the hex bolt. The new gasket for the bottom is ordered so it is just the removal of the 10 hex bolts on the plate, remove the sensor, replace. Anyone know the torque requirements for thse hex bolts? I am almost tempted to replace the knock sensors while I am here since I did have one alarm on me over the summer after it more than likely got wet.

    Heavy mentioned trimming off a lip of the Maggie but I would guess this is the piece that he actually got....

    Re: Oil Pressure Sensor Sender Failure

    Im weary to grind it off that close to that bolt and grinding with so many open holes in the engine bay right now where that stuff is going to end up. I have a couple of towels over the ports and stuff right now but I still worry about anything finding its way into the engine.

    Re: Oil Pressure Sensor Sender Failure

    I duct tape a shop vac hose next to whatever I grind on.

    Catches most of it.

    Just spray with a degrease solvent first.

    Re: Oil Pressure Sensor Sender Failure

    Rey,

    I had the exact same scenario happen to me earlier today. Monitored everything else and came home to research it. Sadly, I just passed my 100k warranty. Thank you for the information and part number. I just ordered the part, should be here in a few days.

    -Chris

    Re: Oil Pressure Sensor Sender Failure

    Funny I should spot this thread. My sensor went this morning. Maxxed out then after a couple of hours went to blanks and alarms started chirping. Not fun to listen to bongs all day.

    heavy, thanks for the info, I'll try it out without removing the maggie.
