Thread: i got the Oil Pressure Blues

Tweet

hey dude, story is one thing fact is another.Fact 1 soilds are just that, solid Fact 2 hydrolics need oil pressure to pump up, in order to work. The solids will run and continue opening and closeing the valves without oil until they wear out and fry. hydrolics on the other hand will not work without pressure and will not open and close the valves. The post is about a guy worried that 30lbs pressure for a small block might be to low.

What are hydrolics?

So, If I have 10-15 lbs at say 750 rpm's at the light, and then I stand on it, and look at my gauge at 6000 rpm's, and it's reading 30, I'm ok ?? Or is that 10 lbs for every 1000 rule apply, or is it the pump is only made for 35 ?? Or is it as long as there is a oil film there, I'm ok ??

I am going to go for the old 10 psi. every 1,000 r.p.m.s.Even though oil has changed over the years this still works for me.If you want go with the oil film there.Why do they call it an oil pump anyway? L.O.L.

Do you know what a bypass is? Too much oil pressure can cause
problems to and that's why they have those spring loaded bypasses incorperated in the oil pumps. P S It's the oily film that reduces frictionwhich reduces heat and ware

It is for my way of thinking for the street. I would only accept 30 lbs if it was a 50's vehicle, and stock engine. Grandmas car for the store run, it would be fine.

Ahh,I see you understood the point I was trying to make Grasshopper.

Why does G.M. sell plugged bypass's than?

pizzi-man, your right about the hyd. lifter. most of the time I've found the lifters to rattle long before the rods knock, but for a built up motor the pressure is to low.

boy if you think that you need 10 psi for every 1000 for something mild you are way off for it to run ?more psi to apoint takes hp to run that pump and eats cam gears .yes yes yes that what you need on a mild small block 70 psi cold at idle and some thing that will not need to see the hi side of 5000 ???? have had alot of big block that had 65 psi and went to 7500 and with low valve sring psi how much oil dose it take to keep the lifter up ??

He never really states how mild or wild the engine is. After all this is a Club Hot Rod forum one would think he would have a semi-radical engine.

My LT1 is sitting on the dock waiting for me to pick it up. I've got the fan kit waiting to be installed and next week I will have the 350 turbo with OD. What I need now is a good and reasonable priced wiring kitfor the car, not the motor. I get all this together and I will tell you what the oil pressure should be in a built up motor. If I hear them lifters making noise you can be sure I'll be checking my oil

ok that would be a good point .so if he is try to make hi hp at 6000 + why have a hyd cam in it? and he need to find if the oil gauges is good? and if this car is running hot try some new oil in it and filter and if this dose not work and he needs to find out what he as for a pump and if stock. go to hv oil pump

You are right there.I saw a purple 57 chevy and assumed maybe he had something radical.I guess the hyd. cam might of given it away. What is it they say about the word assume?L.O.L.Did I mention the 57 Chevy is purple.

I think there might of been a song about this.I think it goes something like this.I've got a 57 Chevy with 4 on the floor, glass-packs,cheater slicks 454. I'm just a red-blooded fun loving all American boy. O.K. so he does'nt have the big block.It is still a cool song.L.O.L.

i can fix that for him rigth fast
