Forged EJ25 Oil Pressure
Hi all,
Just wanted to double check something with you lot (and get opinions) on oil pressure. I know this has been asked a bit in the past with varied results. Took the car out for a run this afternoon and the oil pressures are looking a bit suspect. Showing 1.8/2.0 bar oil pressure at hot idle, and 4.0/4.5 when just cruising along. Previously the pressure when driving has always been at least 5.5 bar, should I be worried? Bearing in mind the car had been given a hammering with lots of boost.
Any thoughts? Thanks in advance

Might be worth checking oil level, I had a lower than normal oil pressure reading when my oil level was on the lower mark on the dipstick. (2.5 but not fully forged) what pressure are you getting on cold start up?

Nice one cheers guys,
pressure on cold start is generally around 6.0 bar. Oil level is all good and was only changed a few weeks ago (millers motorsport 10/50) only used on weekends so should still be pretty fresh.
thanks for putting my mind at rest!

Sorry to be a pain, but daz what does yours do when it's on boost? Should it rise a lot? Mine only rises about half a bar when fully in boost (so about 4.5) just don't want to smash this build to pieces!

this is the original lamco gauges that came with the car. I've ordered a couple of prosport gauges, I know they're not as good as defi but surely more accurate than lamco. Seems like an odd issue overall, searching 22b, here and a couple of other places people's pressures seem all over the place. It's a struggle to know what to trust and believe!

This is straight from the Subaru PDF Workshop Manual I have.
Mine sees 6bar cold idle.
Then at hot idle at 80 degrees I see roughly 2 bar and 4-4.5 bar when driving.
Mine has always been around this. It's dropped slightly but not much.
