Gents,

I'm curious what other people with aftermarket gauges are seeing for oil pressure on the 3.0.

I just installed an aftermarket oil pressue gauge in my Runner and was surprised to see that at startup, the thing pegs over 100 PSI. I know the oil is cold, but I thought the bypass valve should have popped and kept the pressure below 75 PSI or so.

After I drive it and it warms up it has 25 PSI at idle in gear (auto trans), 50 PSI driving at 2500 RPM on the freeway, and the gauge pegs over 100 PSI when running hard through the gears, over 3500 RPM.

I am running synthetic 10W30 oil.

I confirmed the numbers with a mechanical gauge, they exactly correlate.

The new sensor is installed immediately below the factory sender, just forward of the oil filter.

The factory gauge reads at 1/4 at idle, never higher than 1/2 when running through the gears hard and has read that way ever since I bought it 4 years ago.

Anyone else have numbers that show this high of pressure?

Malfunctioning bypass valve? Or, just really good oil pressure?

Switch to 0W20 sythetic oil? More flow, less pressure?


Thanks,

Mike

 

high oil pressure usually is done by the factory because of tight clearances between engine bearings, im not sure what the clearance it supposed to be for the 3.0 but i know that some high revving hondas run 0W20 and hit over 100psi at high rpm because of .005" clearance between crank and rod bearing

 

Hmmm My factory gauge runs at the first line at idle and just above the second line at 2500 rpm's. Thats with 20w50 Syn. with 10w30 it was a smidgen lower.

 

Anybody with aftermarket gauges have any input on what they see for oil pressue on the 3VZE?

Thanks,

Mike

 

Bump again,

Somebody has to have an aftermarket pressue gauge on a 3VZE,

Anybody?

 

i have some autometer ones on my 22re with their senders and my truck reads 75psi at start up and around 15 at idle when warmed up.
