High Oil Pressure
« on: April 09, 2014, 08:59:02 AM »
So I did some research last night and I got some mixed info and before I go and bother Mr. Green anymore than I do I thought I'd reach out here first and see what input I can get.

Here's my situation.  I feel my oil pressure seems very high compared to the common consensus.  What I've read is that it should be around 20-25 psi at warmed up idle and 75-80 psi 3000 rpm's and up.  At warmed up idle I'm right around 30-40 psi and my idle is right about 1000 rpm's so I guess that is about right.  The average idle I believe is around 800-900 rpm's correct? So I guess I could see 200 more rpm's would put me right around 30-40 psi.  When I'm at 3000+ rpm's I'm well above 100 psi.  Normally about 115-120 psi. That seems really high to me. So my question is is there such a thing as too high oil pressure? What could happen with oil pressure to high? I know this can stress my pump but what else is this going to hurt?

What info do you guys need to better determine what I can do to lower this or if I even need to lower it?

Thanks in advance for input you can provide.

What weight of oil do you use?

I run 5-30 and notice 90+psi at WOT.  130psi does seem a little excessive.  I'll be sure to check this weekend when I'm next in the car.

So I'm running 5-50 could that cause high pressure?

I'm not exactly how, but I'd think viscosity can make pressure vary one way or another... Throw in temperature and I'm sure it all factors into oil pressure at any given time.

I myself use 5-30.  Will be sure to grab you some numbers Fri/Sat.

Start-up (cold idle) oil pressure, 70PSI
Warm idle, 20PSI
WOT PSI, 75PSI.


Swear I've seen it higher, but those were the readings I got yesterday.

Thank you for checking.  Just curious are you boosted and would that make a big difference?  I did do a little reading this weekend and I'm going to try a couple of things to try and bring it down a little bit. I've read mixed reviews about the filter that I'm running (K&N) some are saying it will create higher oil pressures but some were saying that it doesn't.  I'm looking into other brands that are comparable to it.

What oil filter are you running if you don't mind me asking?

where is your sending unit connected at the same line which is feeding the turbo? because since the turbo its a restriction could be causing a higher readings , maybe switch it to a different output if you have it connected on the original honda pressure unit outlet you could get a oil filter sandwich to get a reading that is not being affected by the turbo thats my two cents

Sorry for the late response..

No boost.

I use a NAPA Gold filter, which is a re-branded Wix filter.

Conventional Valvoline 5-30.

Pressure gauge line  is running from the Oil Pressure Switch location.

I got the car out again this weekend, and did a Cold Engine WOT pull at it was 85+PSI.  Yours does seem high... But I don't know when it's considered "too" high.  Or what you could do to drop it.

Built motor right? Any porting or shimming of the pump?

Mine was a lot higher than yours. But we were shooting for high pressure.

EDIT: I guess i shouldn't say a "lot" higher. But on my autometer gauge, it stops reading at 100psi, and the needle would wrap around almost to zero.

Yes the motor is built and I don't think the pump has been shimmed I will double check. So do think it's going to hurt anything having the  pressure this high?
