Check oil light

K20 that sounds really low.. my oil pressure is at like 80psi cold..

Change your oil pressure switch 1st. easy simple fix to find out.

 

[da9_vito]

And if your oil pressure is that low k20 please rebuild your shit lol. a b18a1 should be around 60 to 80 psi like Prozon said.

Oh sorry guys I meant to put when the oil is hot but its been a while lol

Oh and my b18 isn't running it is getting rebuilt lol

ok even when its hot it still shouldnt be that low. 40 psi is like the lowest it should be.

That's not what the manual says, it says idle 10 and 3krpm 50

I run mine balls to the wall and it has never dropped below 40. Sounds weird to me.

Its not uncommon to see oil pressure when warm sit at about 10-15psi.

The idiot light comes on at 1psi of oil pressure.;

When my rebuilt motor was cold I would idle at 40psi oil pressure, when warm between 10-15. I have friends whos motors are like this as well. But it could also be how we have our oil pressure sensors setup, though ideally it shouldnt really read different than normal.

Never had an issue

From most of my experiences when you see the light, damage has already been done. When the light comes on there's either no oil or it's not flowing. Either way your pistons are going to start to gall and bearings will take heavy wear very quickly.

 

[k20wagon]

Well it shouldnt go below what I said but can be higher.

 

[da9_vito]

What weight oil do yall use?

What weight oil do yall use?

I run 10w40

Sent from my EVO with tapatalk.

 

[k20wagon]

I use 5w30 and those are the specs minimum from the manual.

OP's problem sounds more like a faulty switch/loose wire than anything to do with low pressure. His motor would be done by now if that was the case, or at the minimum starting to make some funny noises.

You can test it by hooking an oil pressure gauge where the oil pressure switch is and turning on the motor. The oil pressure will always be high on start up. Cold oil is less viscous and therefore pressure is going to be higher. As it warms, the pressure will drop.

The manual does say no less than 10PSI at idle and no less than 50PSI at 3k RPM as k20wagon mentioned. Mine is 90psi on start up, and ends up at 15 at idle after its warm.
