I bought an oil pressure gauge today and i need to know where my sender is...
I think it is located near the oil filter.
Should i drain my oil before i take this out?
Thanks a bunch...

 

If your talking about your 92 shadow.... Yes it's a single wire sender above the filter, your going to loose some oil when you pull it but there's no need to drain the oil.

 

ok, i installed the gauge today and found that the oil pressure is about 60 cold at idle, when warm it goes down to 20-40 and when booting it jumps up to 80-90. At warm idle for more than 10 seconds it jumps down to around 10psi.
Is that normal?

 

10 psi seems a bit low to me, but it's within the specs. My '99 Neon R/T never dropped below 25 psi oil pressure. When I would take off on a cold start it would peg the 100 psi oil pressure gauge at 3,000 RPM's and up. It normally held 25 psi idling at operating temp. and 70-75 psi on the freeway.

 

At idle oil pressure is 10-15 psi and the oil light came on anyway could be a sender problem but the car does seem to want to stall sometimes at idle. Even with good oil pressure. Damnit.
