Hello, I have a new build with oil pressure acting a bit strangely. I suspect a pressure relief valve issue, but I was hoping to get some input. The engine has less than 300 miles on it, but was assembled over a year ago and unfortunately the build notes were lost in a move so some of this...

My 318 LA motor runs fine but at stoplights, the oil pressure gauge bottoms out. How can I remedy this? Rustoleum Plymouth.

I have an issue with low oil pressure during cold starts like you can see and hear in the video. It's ok when warm. It's a stock 318 within unknown history from craigslist. The engine is pretty clean inside, but I have no idea if it has been rebuilt. New oil pump, pickup, lifters, pushrods and...

I know how to wire a pressure switch and a lamp for either low or normal pressure. I was wondering if you are running it thru the ignition, fuel or other system. Just looking for some ideas.

I have for sale a used low oil pressure switch that worked perfectly when tested. The switch is normally closed so an oil pressure light will be illuminated. When pressure is applied the switch is open and the light will go out. I don’t know the manufacturer of this switch but the number stamped...

I had posted back a few months of 5lbs oil pressure on a new engine at idle and 20lbs at cold engine start up I bought a otc oil pressure test kit turns out my oil pressure at cold start is 55lbs then when motor is warmed up 20lbs at idle very happy my question is what is a good us made oil...

I have for sale two single pole, low oil pressure light switches that worked perfectly when tested. The switch is normally closed so an oil pressure light will be illuminated. When pressure is applied the switch is open and the light will go out. I don’t know the manufacturer of either of these...

5.7 hemi idle psi is 10 roughly at temp. Goes up to mid forties on throttle. Haven't checked at WOT. Tried putting Rotella in just see if it gained pressure but did not change. Did some reading ,and some people have a low as 6 at idle,and as high as 40+. Question is should I worry,and should I...

hello everyone, i rebuilt a 318 la back in may , all new bearings and rings, cam, etc, it never gets past 25psi at 4k-5krpms, less than 10 at idle , its got a brand new oil pick up, ive changed the pump 3 times, the 3rd one i put a mopar performance spring in it, i run valvoline vr1 20-50 its...

Hi all. Had a buddy who had his factory roller cam LA 360 rebuilt. Upon start up and run, in had low oil pressure and never developed good to high cold pressure. (This was like 10 years ago, so going by memory...lol) I have checked so far: Driver and pass oil galley plugs are there Plug under...

stock LA360 with a small cam, and headers. The oil pressure when cold is never over 45psi, when warm it is at near zero. I replaced oil with 20w50, in hopes that it would increase some pressure, it may be 10psi when warm now, still never increases above 45psi no matter the rpm. Next step replace...

...volts can cause irregular meter readings on some gauges. Could the cheap gauges and/or low battery volts be throwing out the very low oil pressure reading? This is my best hope. The PCV is stopped up or something because she is pushing oil out the filler plug and PCV on the passenger side...

Hello folks, I have a 1972 Dodge Dart with a 318 that I have owned for 2 years, it has 13,000 actual miles with no engine modifications. While driving it this weekend on the highway the oil light came on, I pulled over and checked the oil, it was a quart low. I added a quart and the light...

I have a fresh 410 stroker. Bottom end is a eagle forged kit. Milodon 8qt pan milling HV oil pump. When the engine starts it has 60psi of oil pressure at idle, once it reaches running temp drops to 10psi at idle (1000rmp). Touch the gas and pressure jumps up to 40-50 psi. This motor doesn't have...

Hi everyone. I recently bought a 1972 Plymouth Scamp with a 318 and 904 automatic. The engine/Transmission has to come out because of a broken flex plate. I have a question. The engine starts up fine with no noises besides the flex plate scraping... ok I didn't run it for long. When the...

My new engine is having an oil pressure issue. At idle I make 25psi hot, 50PSI at 1000 rpm and 65+ above 2000 rpm. I've been doing some freeway testing and after 15 min at around 2,500-2,000 RPM I got off the free way and oil pressure dropped to almost zero. We're not talking hard on the...

need some information on a problem I have, was driving my dart just cruzin along oil pressure was 60 psi , then for some reason it dropped to 20 psi while driving same rpm. Got home did a quick assessment of situation notice very little oil lin price valve cover. Pulled distributor, spun oil...

On a road trip now '72 318 auto. Changed out my Castrol high-mileage 25W-60 wt. (not really available in the USA) for straight Quaker State 40 wt. before I left La Paz, Mexico. With the 40 wt., factory oil pressure gauge reaches the second graduation (near the center of the gauge) when cold (40...

New build lots of used parts. 360+.030, J heads. fresh turned crank full grove main bearings. opened up oil passages.. solid cam .365 intake lobe .373 ex lobe using the old 273 type lifters{dumb bell shape}. so when its cold with 30w breakin oil I get 50psi at idle but as soon as it warms up to...

Gooday from down under Long time reader first time poster I am having a problem with my recently rebuilt 318 la oil pressure staying low After running in the cam in, i noticed the oil light flickering on at idle, Fitted a gauge to reveal about 18psi cold & 10psi hot at idle & a...

Need some help...trying to figure out whats wrong. I recently bought a 340 and I've got low oil pressure. As I said, I bought this one, did not build it. The engine had been in a guys duster. He pulled the engine and sold the car, and was in the middle of putting it in a truck when he had to...

I have a 318 (I believe it's a 71) that I just rebuilt. I primed the oil pump with a cordless drill and I got 60psi cold. I broke in the new cam yesterday and noticed that I had 20psi oil pressure(two different gauges). I diagnosed this as the thin 10-30W break in oil. I drained the oil, changed...

Hello everyone. My 74 Dart 318 runs well with Edelbrock heads, intake, Purple stripe cam. The oil pressure drops to 15lbs after warm up idle, and up from 40 to 60psi under throttle. Should I replace the oil pump, and, can the pan be dropped without pulling the motor? I now reside in...

Quick question: bought a used 451" motor that is fully race prepped. I won't go into specifics but when started and cold it pegs out the oil pressure gauge at over 110PSI. Typically it is still running over 80 psi at the finish line. Is this normal and adequate. Even when I didn't turn the fan...

Just great, I am working out of town for a couple more days. The wife calls and said the car is throwing a warning for low oil pressure. At least she was smart enough to park it. It's a 2013 with about 5000 miles on it....if that. I m hoping the sending unit took a crap, but here is what scares...

...1/2 turn after play was removed (approx .025) Could this lifter have collapsed? Or be defective? and if so, could this cause low oil pressure? My next step is to pull the intake to inspect the lifter, I guess. Has anyone else had this failure with so few minutes of running on an engine...

My sons 416's issues continue ! the hot idle oil pressure is only 10-12 pounds - this is with engine temp 180-190 and idle around 1000 rpm, using Valvoline VRI (NSL) 20/50 and Napa Gold (Wix) 1085 filter. Initial startup the pressure is 40-50 but drops to 10-12 when hot ?? this is a new...

I recently had my slant six machined and completely rebuilt. I did the rebuilding, a shop did the machining. It was my first rebuild and I made a lot of mistakes along the way, but I got her running and thought everything was going good until the oil light came on :( I don't remember if the oil...

...to the 215~220 range. Now she still gets in the 190~200 range and it still stresses me. i think my main heat spike is coming from low oil pressure at idle I run a synthetic blend 5~30. And I currently have the equux some oriely off brand gauges in. I have these gauges in the past and they did...

The engine is a 71 318, RHS X-Heads, KB pistons, a Lunati cam, Hughes rockers, Melling HV oil pump, Kevoco Pan and pickup. The typical machine work was done and every clearance was checked when I assembled it. All the rods and mains were between .0015 and .002, but I don’t remember the...
