Car going in for service on the 26th of October to have this checked out and fixed...

Changing the water pump as well - as a precaution - while at it :-)

 

I've had the issue and was at least partially re-assured that there was a normal oil level with the dipstick....at least its something you can verify in the 996. That's all I'm saying.....

 

happened to me yesterday. My first thought was WTF? Then I did a search, read this post and my fears were suspended.

 

It was a faulty sensor that had to be changed so that part alone cost me about CHF 100 + labour + VAT (around USD 100 + all the extras)...

 

Guys, what's the proper torque for the tightening of the Oil Pressure Sensor?

 

There is no straight shot to use a torque wrench even with an extension unless your emgine is out. I just went by feel. There's an aluminum crush washer on it so you just need to make sure it's tight enough to crush that lightly to seal.

Err on the loose side if in doubt and you can always tighthen it more if it leaks. No fun if you strip or break the thread there.

 

Thanks! I changed it today and an oil/filter change (Joe Gibbs) then drove the car a bit and once warmed up, the pressure sensor was a lot more responsive than before and it made it very obvious that the old unit was faulty. And no more "Oil Indicator Failure" fault and no more heart beat skips because pressure doesn't suddenly drop to zero during WOT. Happy camper!

 

I know the feeling haha. Btw, another indication the sensor is bad is when you turn the key to the last position before cranking, the oil pressure should read very close to 0. If it reads 0.5 or more, the sensor is bad and can fail soon.

 

Thanks for the tip. Hopefully I won't need to worry about it for a while.

 

so I take it "took all of 15min" means you wont need to drain oil to do this?
got this twice, it comes and goes so fast I cant see a change in the oil pressure. its happened twice in about a week span or 300 miles or so.
also this is on a 04 996 GT3. looks very accessible which is good news I guess/

 

The sensor is on top of the engine, the oil sump is at the bottom... No oil will be lost when changing the oil pressure sender/sensor...

 

 

K1 - your GT3 is a dry sump which means the oil tank is located behind the sender you are going to replace. Even so, no oil will come out of the oilway apart from the small amount inside the sender unit itself. Its vey simple to replace - if awkward - and shouldn't take more than a few minutes if the engine is "cold". I've replaced mine a couple of times.....
