B16a2 oil pressure drops to near zero after warm
Hey everyone,
I just installed a Depo electronic oil pressure gauge yesterday. Drove to school today and noticed that it's almost at zero psi on idle and the motor is warm,obviously. It moves when im on the throttle but I cant remember what psi.Car idles fine at around 1k and doesn't stall or anything. OEM oil light isn't coming on obviously
The turbo build has been on for a few months now so I would think if my bearings were bad, my motor would've been toast by now or my turbo. But it still pulls great, vtec still engages, compression test reads 210 on all 4 cylinders, turbo is brand new and there's not a single leak, no leaks on the motor. It's been running for months and nothing has been changed except the addition of this gauge.
The way that it's hooked up is I have a T from the back of the block with the stock oil sensor on one end, I have a short 3an line to the firewall where the oil pressure sender is,then there's another T and the feed line goes off the other end.
Bad sending unit??

Are they vtec safety checks disabled in your tune? Because if the oil pressure is actually low, it should not be engaging. Also if it is really that low, it should not be running and somthing would be going wrong. Im thinking somthing is faulty like the guage.

Talked to one of my buddy who owns a shop and he tells me the sender that comes with these gauges are shitty.
at WOT it read 55psi, idle at cold is at 25-30psi

Re: B16a2 oil pressure drops to near zero after warm
You aren't the only one with this problem with the depo oil gauge. Mine reads the same thing after it's warmed up. It actually reads at 10psi at idle. I hope your buddy with a shop is right about the shitty sending units because I was thinking about checking the bearings. I have a set of defi gauges in my other car which I might pull out and try. I stuck an autometer mechanical oil pressure gauge on there and after it's been driven a while it read at 15 psi at idle.
Not to hijack your thread but does the type r oil pump really flow more than like a b16 or b18c oil pump?
