Car: 1995 S14
Engine: S14 SR
Mods: S15 turbo, rocker arm stoppers, thicker head gasket (can't remember what kind or thickness), greddy profec b spec ii, many other odds and ends all professionally installed by the now defunct Heavy Throttle.

search strings: "oil pressure", "high oil pressure", "oil pressure high"

About 2 days ago, I started to notice that my oil pressure seemed VERY high. I know that upon a cold start the pressure can be about 75-80 psi and it should usually drop to around 45-50. Even when the engine is fully warmed up, I've noticed that the oil pressure remains really high. At 65 mph at about 3000rpm the pressure is about 75 psi.

If I start to accelerate and raise the rpm to 3500-4000 the oil pressure goes to over 90 psi. I've searched here for potential problems and found threads mostly concerning low oil pressure but only 2 or 3 that had anything to do with high pressure. A bunch of people stated that high pressure is not a bad thing and that low pressure is more alarming but I'm still worried if the pressure says that it's over 90 psi.

Also, on my way to work today, an oil leak coming from the turbo side of the engine was dropping oil all over my exhaust. I'm going to see if I can take some pics and post them later today (I'm at work now and don't have the capability to post any).
