noticed this last night.

while driving, holding RPMs steady at 3250, the oil pressure would go from 60, bounce around down to 40, then go all the way up to 70 for about 10 seconds, then start to bounce around again. and at a stop, its showing zero pressure @ idle.

this pisses me off/worries me. can anyone advise anything other than the usual drop the pan and clean the pickup tube stuff?

its a JDM B18C

Maybe its your Super Tech oil filter.

Seriously though, i have seen this a few times, and a few times it was caused by low oil level. Im assuming youve checked yours?

i bet this is what it is...happend to me before... to oil pressure gauges...eltric ones go out and manuel ones can leak inside your ride...

 

that picture is for referance only...

but yea its a cheaper full sweep gauge.. but its strange how it would fluctuate like that... after being fine.

when they go bad do they give false readings or just not do what they are supposed to do?

what if the gauge reading is true? what would be the cause?

 

Dirt trapped in oil galley's, low oil level...

The only other thing that could be wrong is the oil pan is dented kind of like the one in your picture. See how the pickup is dented in your picture, something had to dent that which means that the pan is covering the pickup cavatating the oil.

 

Most likely the problem comes form being low on oil ..when u take turns does it go low or the whole power band???

 

oil is at proper level. and i even added a little bit more just to make sure.

 

update:

went to a friends house 30 miles away. i had it at like 4000rpm for about 24 mins and the gauge was bouncing all around even as low as 20psi...

drained the oil to check the magnetic plug, this is what it showd:



to me thats just the normal fine shavings.

what do you guys think?

 

i dint think there is a such thing as "normal metal shavings" the metal has to be coming from somewhere... maybe bearings?? thats the most common place. either way if your 100% sure its not the gauge id change all the bottom end bearings (main n rod) before u kill ur crank by spinning one of them

 

so your teling me in an engine with tons of soft metal parts rubbing together at high rpm isnt going to create any shavings at all...i wish you could see how much im rolling my eyes...

 

why ask a question if your just going to bash what someone says??? your asking for comments yet you have your own pre-concieved notion of what you want to hear. If that's the case just go get a mirror and talk to yourself rather then trying to get people to make u feel better and tell you everything's ok.

Replace the gauge with a more accurate mechanical unit, these guys know what theyre talking about.

Oh, and a side note, i rev my motor to 8k everyday with even softer "Bimetal" bearings in my lsvtec as opposed to your "Trimetal" in your B18C so explain this to me too please, i fear i have been living in a honda fantasy land and have learned everything totally wrong. Please help me on my path to be correct

because 97% of the people in here have no f'ing idea what they are talking about.

 

i say you have a engine problem...............i change my oil like every 1000++ miles or so....... it see like 8-9k everyday.... i never see metal shaving in my oil.........

i think you are included in the 97%...

 

lol, you're a funny guy ur next thread is gonna be "HELP!! loud knocking sound from engine!!" you truly are a F*CKING IDIOT have a nice day

 

lol, your probly right ,there should be no metal shavings in your oil unless the engine is brand new and being broke in but even then the shavings are more like dust than actul shavings and the only metal in the bottom end that would stick to a magnet is the hole rotating assembly minus the pistons

 

oh well, ignorance is king! i hope this guy blows his motor, and when he does im gonna LOL IN HIS FACE

 

the only way you are truely find out is hook up another oil pressure gauge to it.

As much time that has been spent bitching about other peoples opinions to your question you could have bought a new mechanical guage had it shipped and bought a braided line for it to prevent the cheap plastic line from leaking in your car and installed it by now.
