i have a few questions from rb owners. my oil pressure bounces between 80-110 when cold started and settles around 20-25 at operating temperature. im running valvoline 20-50 oil and am oem oil filter. is this a good oil pressure for this engine?

 

Oil pressure will always be higher when the engine is cold. It seems alright to me.

 

yes that is fine, is this a r32 or r33 motor?

 

Its an r33 series 1 rb25det. The reason I was wondering is because there is an oily substance in my coolant...and I've only put clean 50/50 antifreeze and water in it. But my oil is fine and not all milkshaky. So idk if I'm losing oil pressure or something somewhere into my cooling system.

 

your motor have a ignitor or no ignitor? if none then its a s2 has the ignitor built in the ecu

flush the system n see if it still there

 

its an s1. it has the igniter chip at the back of the engine ontop of the valve cover.

and ill flush it out and see if that clears it up. if not then im thinkin the headgasket didnt seat right when i put the head on it a couple months ago.

 

did you use a oem or a aftermarket? cometic, greddy, apexi? arp or stock head bolts

 

Its a tomei mls headgasket and it has arp head studs

 

you use copper spray on it?

 

shit flush it and see if that fixes it before we start talking a h/g
