Whats up everyone does anyone know what your oil pressure should read at idle?? it was normally around 20-25psi until recently i got new pads put on (i know that has nothing to do with oil pressure) but now...my idle is steady @ 1500rpm WARM! and oil pressure is steady at 45-50psi WARM! something seems weird...any help would be appreciated...thanks in advance.

 

It should be no less than 10psi at idle and about 50psi @ 1500 RPMs and above.

 

what could cause my oil pressure to run that high??? and my Idle..just seems kinda whacked.

 

Did you change your oil recently? That would do it. As far as the idle...

 

yeah..not too long ago..i checked my oil today looks fine.

 

Fresh oil will normally yeld better oil pressure but im not sure about the high idle. Are you getting any CELs?

 

Yeah for a bad IAT...thats in the mail...but i wouldnt think that has anything to do with idle being high...would it?

 

as per the honda service manual oil pressure for the b16 should be 10-15psi warm idle, and 50psi at 3000rpm in some cases there are 84mm oil pumps on b16s, and some have 80mm, my oil pressure is 20psi at 700rpm, and 82psi at 3000 full warm idle, using 5w-30 mobil synthetic.

it could be the iacv plunger sticking, brake cleaner works well to unstick it, also check for a vacuum leak, if the leak is only big enough for 1500rpm idle, it wont trow a code, its when it tries to pass that rpm that the engine cuts it, and the surging idle takes place.

 

sweet, yeah ill do that..change my oil as well..thanks for the input everyone..ill keep you updated as to what the expletive is goin on...thanks again!!!!

 

Does anybody know what a b18's oil pressure should read at idle?

 

so i changed my oil...fresh..still the idle is nuts...could you tell me where the iacv is located??? thanks again..

 

nevermind i found it...do i just shoot the brake cleaner in that bad boy???

 

just pull it off the car, and clean it out, and reattached it.
