Turbo oil return?

Wrapping up my fix on this. I was able to fix my oil gauge reading. My oil gauge on the cluster pegged at max after engine start. It hits the stop at max. This is a different issue than what most people experience which is the gauge reading zero (this seems to be related to bad oil pressure...

Ah, I understand not wanting Cars and Coffee at your house. However, everything you are selling fit on a NSX on way or another ;)

Where in socal? Should do a proper "garage" sale for a gathering at your place.

From Heineken's reply above, 26 ohms should fall between 4 to 8 on the guage so I suspect the guage is inop. Next oil change, I can try to test the pressure.

When disconnected and engine off, both the old sensor and new read open circuit, measured from pin to metal housing. I can only measure resistance while the sensor is under pressure. The new sensor came from Amayama.

OK, diag time. The oil guage is at zero with engine off. The oil guage goes to 8+ with engine on. With the sender disconnected, the guage is at zero with engine on. The sender is measuring 26-29 ohms at cold idle and the guage goes to 8+. I guess the only thing left is to measure the...

Need the collective help of the forum. I replaced the sending unit with oem and the pressure guage is still pegged at beyond 8. No change from cold to hot, rpm, etc. Perhaps it is in the cluster. Capacitors?

I remember BMWs of the 90s, the oil pressure guage would swing up and down wildly with RPM. I thought it was pretty useless other than stating there is oil in the engine. For that, I still have the oil warning light.

When I get the new OEM sensor, I will measure its resistance out of the box to get the base value at least.

Thanks. Looks like the sender is expensive, about $350. I will get one and be ready to replace at the next oil change. I saw that it might be easier to replace from the bottom instead of the top

Max meaning it is pegged to the top. Cold start, hot start, pegged to the top. I take it your read somewhere in the middle of the guage.

With oil midpoint between the low and high mark on the dipstick, my oil gressure gauge on the cluster pegs at max after engine start. Is that what everyone experience?

So many weird things comparing yours and mine. The rpm at 15 and 25, the max emission for each test, etc. Seems to be a crapshoot other than grossly failing.

Since the test had to be in rollers, the tech asked me how to turn off the TCS. The tech did ask another mechanic how to clamp what I assumed to be something related to the a vacuum tube. Since there are two exhaust paths, I think if you don't pass with one, might want to try the other...
