this normal?

[jasonroman]

oil pressure guage reading.
normal or should i be worried of things to come?

[russgt]

Thats a little low, in OD at 75 you are at what, maybe 2,500 RPM? Generally speaking you should have 10 psi per 1,000 rpm or more. Looks like you are just under 15 psi. what weight oil are you running? Do you have a different oil pressure gauge laying around that you could use to verify that your gauge/sender is working properly?

[jasonroman]

thanks for reply.
unfortunately i dont have another guage to test with.
if i did, what would i need to do, take apart dash and get this guage disconnected?
been cought up lowering the truck, bunch of issues. planning on attempting the notch later today.

as for if dash needs to come apart... i have never taken it apart, but need to figure it out. want to make lights brighter. dont remember what oil is running. i know i need to change it soon. any advice on what i should use?

[jasonroman]

looks like this is the least of my probs right now...
putting in a c notch and cut thru brake line!!!
can i fix this??

[3r!c84]

lol gotta get new lines bud

Actually, you can pick up little brass couplings at O'reillys, or other parts stores.

I'm using one on my rear brakes at the moment, due to someone in the past wiring a broken shock to the axle. Is holding real good.

As far as the oil pressure, I hope the gauge or sender is bad, thats pretty lousy pressure if its reading correct.

If you fix the brake line with parts store fittings, only use brake line flare fittings, not ferrules and compression nuts.

And while you're at the parts store, buy one of those cheap 15 dollar oil pressure gauges with the little plastic tubing. Install it temporarily and see if it also reads low. That's much easier than going into the dash and not really knowing if you have an oil pressure issue or not. The cheap mechanical gauge will tell you the truth one way or the other.

[Dru]

Used compression fittings on mine, I'm sure people will probably say that's a no no, but I had already been driving for a few days without rear brakes, and I didn't figure giving it a shot could hurt anything.

I wouldn't do it on front brakes though, but then again I wouldn't drive with no front brakes either, the rears don't have as much importance to me. Have fun power braking it for a day, lol.

I like to carry atleast 30 lbs of oil pressure, at all times. The big block in the truck carries 55 lbs at 1,000 rpm idle, while at full operating temperature, standard oil pump also, no special high volume/pressure pump spring.

[3r!c84]

id rather walk and save myself (and or others) then do that ^

[Dru]

lol, you must have never lost rear brakes, it isnt that bad.

[3r!c84]

nope. only lost them all. good thing it was a manual and i could engine brake for the most part to get it home.

[Dru]

Ok...so you make a comment that you would rather walk, and save yourself, or others, but you drove home with entirely no brakes at all, when you could have stopped and had it hauled? lol good one.

[jasonroman]

thanks for replies and info. ill got tomorrow to autozone and see if they have a fitting that will work. if not ill take line out and go back to get the length of pipe.
if i can just use a fitting, can i just add fluid and go, or do i need to bleed. if so, what the right way to do the bleeding??
thanks

[ChevyC102007]

The small block in my truck carries around 45-60 at idle (around 700 rpm) and about 45 at 65 mph.

[jasonroman]

well ill be going to parts store in a little while to see if i can get brake line i broke.
should i get a new gauge to test my actual pressure?
is it a guage i need or something else?

ive noticed that sometime ill be driving around and it does not move from start to the end of my drive. sits at zero.
other times it moves, sits in the middle. or low.

could it be bad guage? sending unit? or something else??

what do i need to do to get a different cheap guage with plastic thing to work?
some one mentiond getting a 15 dollar gauge.
where do i start after getting the test guage?

not much of a mechanic. so i ask.

[Restrorob]

If your going to Auto Zone see if they don't have a oil pressure test gauge in their loan-a-tool program, Most do.

Go ahead and pick up a new sending unit while your there, You have to remove it anyway for testing. If you find good pressure on the test gauge install the new sender and check your dash gauge, If you find low pressure with the test gauge take the new sender back for a refund.

For the brake line, Don't use a furrel type fitting, They should also have a brake line double flaring tool in the loan-a-tool program as well then use a steel coupler. And yes the brakes will have to be bled afterwards....

If you are bleeding the brakes with the tried and true method of pumping the pedal. Start at the farthest point from the master cylinder, the left rear, and have someone stroke the pedal about 1 to 1-1/2 inches at a time. I know that soundds conservative, but if it is the original master cylinder you could tear the o-rings when you fully depress the pedal. Just go until you dont get any more air bubbles in the fluid at that wheel, then move to the right rear. If you don't have the sectioned master cylindeer reservoir, make sure you bleed the fronts as well. Wouldn't hurt to do those either way.

[jasonroman]

well i went and picked up some line, fittings, and rented the bender and flairing tool.
guess i need some practice on scrap piping. my double flairs aint coming out too good. thought i had one that was decent, and ended up stripping the coupling.
so, now i need to get a coupling tomorrow and hopefully figure out how to get the flair right.
hopefully tomorrow i can get it together and attempt bleeding brakes for the first time.

i was gonna pick up a new guage for the oil pressure, cuz they dont rent one.
but i think ill try and get the brakes fixed and working first before trying
anything else.

thinking when and if i get the brakes figured out, next step will be the oil pressure thing and maybe pick up a tach and try and figure out how to install that too.

thanks again guys for replies and advice on my issues.

[jasonroman]

ok. so i rented tools and failed a couple times. but then cableguy sent me a link and it showed me what i was missing or doing wrong. problem fixed.
brake line on and brakes bleed. not sure if i did the greatest job bleeding brakes, but they are working. and light is off.
picked up a sending unit when i returned tools i rented.. 6 bucks...? sound right?
anyway, looking for the unit now. not sure if i found the right one.
is it towards the back of block near firewall. and under the distributor??
plug going into it has only one wire coming off the back of it???

if this is the right one, then ill need to go buy a bigger socket. dont have one big enuff to cover the sending unit i bought.

whats the easiest way to get at it and swap it out???

thanks again.

[jasonroman]

anyone have a pic of right part or part number???
auto zone sold me one. 6 bucks.
pep boys had a different looking unit.
and online i saw a 3rd different looking unit.

[ont_guy_38]

This is the one you should have ...you should be able to look back there and see which one it is

[jasonroman]

thanks. thats what i saw when i googled it.
but thats not what they sold me.
guess ill be going back and changing it for the right part.
need a big socket to get it off right? anyone know what size?

[jasonroman]

then again, that dont look like the one i have. so dont think the big socket thing will work to remove it.
if i can get the right part.
whats easiest way to get it off.
distributor gotta come off?? never took it off before. so hoping theres a way around it.
thanks for any info

[ont_guy_38]

U got this one?

RUnning a gauge he should have that one either up there as pictured or down under right above the oil filter.
The other one is for a dummy light and choke heater switch.
