Low Oil Pressure Reading In A R34

[dori34]

after driving yesteday for around 20minutes, i noticed on idle that the oil pressure gauge is on 1.3 bar (usually at 2bar) the car still drove normal, idled normal, no funny smells or smoke, if my oil pressure was actually faulty, would i notice it with some of weird idle, vibration or smell/smoke? no leaks of oil anymore, oil levels are fine.

i turned the car off and waited a few minutes and turned back on and it was fine.

after driving again for around 15minutes today, i noticed it dropped again to 1.3bar on idle.

are R34's known to have faulty sender units like how coilpacks commonly die in R34 & stageas.

any help much appreciated.

cheers

I have a Greddy gauge in mine...........

idle 1 kg/cm or less

2000rpm 2.2-2.5 kg/cm

3000rpm 3.5-3.7 kg/cm

4000+ rpm 4 to 5 kg/cm or better.

I don't see that you have a problem.

Do search and you'll find that others have pretty mucht he same or similar reaedings as me. Maybe you just never noticed the idle pressure before?

It also depends on the engine oil ratings...(correct me if i'm wrong) the oil thins out after it heats up...so oil pressure slightly drops.... my GTT sit between 2 and 2.5.....

if your unsure just change the oil....

PS. I use Penrite 15-50 semi synthetic...

yeah i notice my pressure all the time.

its never dropped this low, ever!

so thats why when it happened, i noticed it right away.

im using full syn 5w30, when cold it stays around 4bar, when it warms up and generally it stays around 1.9/2bar so ive never seen it this low.

should i not trust the standard gauge reading ? lol

oil was changed less then 2500km ago (new oil & filter)

well it happened again this arvo, but it was idle on around 1.6 this time.

i turned the car off and turned it back on and it was back to normal.

any ideas?

When I walked into Powerplay Imps once, Ali was working on a car with the same problem. Suspect sensor I think.

hey terry, yeah thats what im thinking as well. cause when i turn the car off and back on, 2/3 times it will go back to normal. well it hasn't been happening for the past 3 days, so far so good even tho i didn't change anything lol
