hi all

fitting an oil pressure gauge will obviously give me more information on whats going on inside my engine as opposed to the oe on/off switch or dummy switch.
how important is it that i keep the dummy switch and run it along with my gauge sender ?
am i just as well not using the dummy sender and fitting my new sender in its place and be done with it ?

im really not keen on the remote braided line set up and think i would be a lot better off going straight into the block with my new sender.

how many of you are doing this ?

at what bar does the dummy light come on and what is a safe bar to be running at and what is too low or high to signal/cause damage ?

cheers siv

 

Have a read through this

Interesting......... Thanks gambit.

A lot on here saying that if your dummy light triggers your engine is most probably toasted anyway.
Any truth in that ?

 

Yes

The Oil pressure warning light or the engine fu*ked light as it is more commonly known as, has an activation pressure is 0.14 Bar (2.1 psi).

So totally pointless as an aid in preventing damage ?

 

yep. but as said in the link its a good indicator on initial prime/start up of potential problems

 

Cheers bud

Sounds like a good idea to run both then

 

I'm sorry, I disagree with that. The switch is set to turn off at 1 bar, that's 14.5psi, give or take.
So what if it reacts quicker up to 1 bar? It might go out, and lead you to think all is OK, but you only have 1.1 bar........

Do as you like, but my OE o/p switch is on the shelf in the garage and the ONLY reason it wouldn't be, and that I would use a remote fitting kit is if the sender didn't physically fit in the space. Even then, I'd think about blanking it.

TBH: with modern stepper gauges, the gauge calibrates while the fuel pump is priming. I never start my engine until the Defi alarms stop, and by that time the gauges are calibrated and doing a better job than the switch. End of.

 

Alcazar I would much prefer to just fit my gauge sender under the alternator but a definitive yes or no to the dummy switch is proving hard to find.

Is a 1/8 npt sender the correct size for dummy switch replacement ?

Remove the oem sender and fit abraded line to remote install your oil pressure sensor

 

Mine has run without the OE oil pressure switch now for over ten years.

IF you new sender will fit where the o/p switch did...and I mean PHYSICALLY fit, ie: enough space for it to go in, then fit it there and put the OE switch away in your garage. It's doing as much good there as it did on the car.
