help on oil pressure gauge

[Skadaloz]

well just did my jdm 7mgte swap...got it running and what not...but wen i turn the key to on the stock oil pressure gauge goes over 120 psi and now its stuck pass 120 psi and wont more no more...if i remove the jdm oil pressure sender unit out and replace it with my usdm stock oil pressure sender unit would it go back to normal?

yes...

If you didn't fry your gauge that is.

What jdub said... I suggest an aftermarket oil pressure gauge.

thats what i did with my jdm 3.0L. just swapped the oil pressure sensor for the big round gold one from my usdm motor.

my gauge used to act funky when I swapped over a JDM engine into my 89, it would rise to the top then slowly descend. When the 86.5 received it's JDM engine, the gauge wouldn't move at all. Now finally when I swapped in a JDM engine into my 92, I made sure to change the oil pressure sender and it works like stock...


not sure why they're different, maybe metric vs standard, who knows..

It's the signal that's different.

alrite ill switch it out...thanks guys...

 

[Skadaloz]

welll i just switch it out and i guess i did fry the stock oil pressure gauge...still stuck above 120 psi...well i guess ima have to buy a aftermarket oil pressure gauge...theres this guy selling one for $30 shipped but its mechanical...so what all do i have to do to get it to work?

 

[jdub]

Buy another stock gauge...post in the WTB section.

 

[Skadaloz]

would 87-88 stock oil pressure gauge work on mine? i have a 1991 supra turbo 5spd

 

[Mk3runner]

It won't look the same

 

[jdub]

Needle appearance is different iirc, but it will work fine.

i actually had the same issue the op described but it wasnt due to a jdm ops. it was due to the signal wire melting on the header. cut the wire hoping it would drop but it stayed at the top. wired it back up 2 weeks later and no change. fired gauge?
