Can anyone help ???
I got a r33 gtst and the oil pressure never goes under the second line (before the 4) but my friends RB25DE r33 goes all the way down to close to 0 when its idle.
The car makes a weird sound when its at idle (she calls it the gremlens) but its like a howling sound. Could that mean the oil pump is stuffed?
as soon as you raise the revs by at least 300rpm the sound goes away and oil pressure goes back to normal levels. (just before the 4 or abouts)
When driving its fine......
Whats up with the beast ? does it really matter to have close to 0 oil pressure on idle ?? The engine is NON turbo...
