Gq oil pres light on but mechanical guage readout fine
Posted: Sun Mar 14, 2010 8:19 pm
on my tb42 i have a mechanical oil pressure guage hooked up and also the std oil pressure light, when car is started and oil rises light breifly disapears but before long returns gradually but mechanical guage still reads 20psi on idle and anywhere from 30 - 55 psi which i would think to be correct, at current oil change is needed shortly but would light still come on even if after market guage is reading such a read out, can any one plz send me in the right direction as to why light would be coming on thank you
