How to increase your oil pressure

when you install an oil cooler like i did my self you loose pressure and in my case i lost about 10 PSI, i have a large cooler and filter relocation
this drop of pressure caused my vtec to occasionly drop out between 7-9k RPM

once i increased my pressure my vtec went back to normal and the car no longer has vtec problems

Now how to increase the pressure
firstly you must remove the exhaust to access and remove the sump
drain the oil firstly if the oil is still good you can reuse it just use a clean bucket to drain it into

the oil pump sits inside there



once you have the sump off you will need to remove the allen bolt seen below
i thinks its a 10mm if i remember right





it will have tention behind it because its spring loaded so be carfull it doesnt fly away when it comes out also when replacing it you will need a bit of force to push it in when you tighten it back up

once removed it should look like this



now you wish to use a few washers and shimmy it up to create more pressure on the spring just a small amount of of washers can create extra pressure needed in the sping
dont go overboard with the washers i allready had 1 and added another 2 i would not go over 4 washers too much pressure and you will start more problems
different cars will require more or less washer to create more pressure if its just a slight increase wanted just add one or two if you do have pressure problems add 3
warn pumps will also loose pressure and require more washers
my pump is brand new so dosnt require this

you want to place the washers inside the piston



now reassemble it all and test for leaks
do a good clean job, you cant test it untill its all back together and exhaust back on
so its recomended that you get a new sump gasket as they normally will break on removal and you will require a gasket sealer as well

this is a quick write up by request so sorry for the lack of descrition

Hi great post.

do you care to put the before and after oil pressure readings?

Just so we know what the stadard or expected figure should be.

Also where do you have your oil pressure gauge? Tee of the factory position?

thanks

[SKREMN]

yes i have a t peaice of the factory sensor

also my car is a b20/b18 hybrid so i want have stock readings and its been three months since i did it and dont remeber my read outs

dont need to drain oil first? lol

[SKREMN]

well yes that would help

good work,

On an unrelated note, the VTEC oil pumps and non-VTEC oil pumps are identical except for a single preload washer on that spring; So this procedure is the same to for a VTEC oil pump 'conversion'.

[SKREMN]

i would say so...
same procedure across most range of honda engines

I think you missed the point of my post. I'm saying that there is no point buying a VTEC oil pump when the non-vtec is nearly exactally the same.

do u know where does the the allen bolt located in ITR engine ?

Only 1 allen bolt in each engine ?

you haved to remove the sump to gain acess to it
