If you want to reseal the oil pump, you'll have to remove the timing belt. Then you can slide of the crank sprocket and unbolt the oil pump. You'll need a new front crank seal as the oil pump slips over the crank. And a new oil pump discharge to block o-ring. The screws sometimes tended to back out of the rear case over the rotors, thus allowing oil to seep out and sometimes leak out or even push out the front crank seal. There is an article on endwrench about it. However, I would suspect the gauge or sender. If you are reading 90+psi then either the gauge is inaccurate or the oil pump internal pressure relief isn't working correctly since it opens at about 72psi. There was a recent post on here about gauges where nipper and others gave some good info about gauge accuracy and how they don't necessarily give accurate readings at the low or high end of the range. -
Have you guys heard of this Cosworth CS600 series High Performance Subaru EJ25 long block and if so what do you think? I'm sure it's not cheap... Says it starts with a new Subaru EJ257 semi closed deck block • New Subaru EJ25 STI Engine case • New Subaru EJ25 STI Forged Crankshaft • Optional Billet Cosworth Crankshaft (CS600X) • Cosworth Forged H-beam Connecting Rods • Cosworth Forged Pistons (CR 8.2:1) • Cosworth motorsport Tri-metal bearings • Balanced to within .5 gram • Complete blue-print assembly • Enlarged Intake and Exhaust ports. • Large diameter stainless steel intake valves. • Large diameter Inconel exhaust valves. • Hi Rev, Dual valve springs • Titanium Retainers • Hardened Steel spring platforms. • Multi angle valve job • Machined port finish • Knife edge port divider • Cosworth S2 High lift camshafts • Valve lash set • Cosworth high pressure oil pump • Cam covers • Cosworth serial number

Yes you can't use a multimeter to measure resistance in an energized circuit because the meter applies its own voltage. With the sender connected to the gauge and energized, try measuring the voltage across the sender terminals. If it has only one terminal then measure that with respect to ground. I think cosworth makes a high volume oil pump for the Subaru's too.

I haven't used them before but might consider it for a lifting effect. I have replaced struts and springs and their related rubber parts and mounts before. 1. I don't know if these would work at the very bottom if that's what you mean like between the spring and seat. The bottom spring seat is usually tapered not flat like the top. 2. Well rubber would probably eventually deterioriate, just like the other parts in the struts do eventually. 3. Zip ties might work not sure if they'd eventually wear out though. 4. Camber might be off a little bit I guess.
