when starting from cold my oil pressure (greddy EL gauge) gets insanely high just at idle, the gauge itself goes to 10 kg/cm2 and it goes beyond 9 on cold, and if you touch the throttle it will continue (and red led will illuminate).
It runs pretty crap while cold and is un-drivable like this (bit of smoke if revved when cold). Once it gets up to normal operating temperature the pressure drops to about 4-2 at idle and will go up to 6 when revved a bit.
I put fresh oil in recently (Motul Turbolite) and its only been driven probably 20 km's since.
My main concern is its got a smaller oil filter (random SR20 filter i had spare) on it than standard as the normal one didn't fit (RB conversion into S13, doesn't clear the engine mount). I wouldn't have thought this would be a problem, but im no expert either.
Please help, this is stressing me out to the max! I just want to be able to drive the car not watch the pressure gauge!
Cheers
