Your oil pressure is too low! It should be between 40 and 45 psi no matter what oil you use! I personally use the 20/50 Castrol in my 440 that was built in 98 and runs as strong today as the day it was built! Sounds like you have a weak spring in the oil pump

This is what I get for running my mouth. But at least I didn’t put any oil down. Saturday after my second pass the engine was running rough on the return road and the oil pressure seemed a little low. But it was only 15 minutes between runs so the oil was pretty hot. I nosed the car into the...

There is just one, under the rear main cap (SBC also has one). It is usually a 9/16" freeze plug, measure it to be sure.

Whole lot of difference between 30wt and 50wt. I'm not 100% with you on this because I've been thru this. I don't like heavy oils and use straight 30wt as my limit but an hv pump will only make very marginal low rpm differences and I think he already has an hv pump on the engine. There are no...

I don't understand "bored for a bigger cam". It sounds like you are having problems with your automatic choke. This can be difficult to sort out, as it can only be done with a cold engine/carb. Low oil pressure with no loose bearing sounds could be cam bearings. Back to the mysterious "bored for...

Brand new, never used, Chrysler 485hp small block crate engine. We had planned to install this engine into a Dodge Street car project however due to health issues we decided to stop the project and sell the parts. It was stored for some time so we had it internally inspected and it's in great...

"Zinc" or "ZDDP" as an engine oil additives are actually zinc dialkyldithiophosphates. Think of this stuff like salt. You pour salt in water and dissolve it. Now you have salt water. You can pour it through a sock, an oil filter, cheesecloth, whatever - and you still have salt water You...

Yes. 3 psi. I looked up a Holley switch and it says 5 psi. Wiring should be C- fuel pump, NC- starter relay/solenoid, NO- key run position. I have seen other ones that look like a plastic oil pressure switch for a light but have 3 spade terminals. If my memory is right (CRS) we never had much...

I got the engine primed, however it still does not have oil pressure. I added a mechanical gauge to be sure and am getting no pressure although there is a little oil in the line (like its trying). I think the pump is doing its thing but I suspect that the pickup tube is not seated or the O...

This first chart procedure was posted for me to use by someone that responded to a different post. I used this method and it resulted in loud clatter. I don't know if it was poor lifter preload smacking valve stems because of a lack of oil pressure or valves smacking the piston. The noise did...

No it should not change your timing. Just helps get rid of pressure and oil blow by.

Well, its used for systems with low or no pressure.

While trying to chase down an extremely loud, intermittent valvetrain tick, I found my rocker assembly in the following condition. I'm no expert, but it looks like one issue is lack of oil, judging by the scuff marks. Not sure if it happened when the engine was built or recent. If current, that...

Here's a good view of the principle of operation That's what I would do

Here is a video I took after I drove it around for about 10min. Car also drives fine and smooth and no white smoke. Here is the oil pressure at cold start up.

This is an interesting perspective. I have been thinking about this subject and have dealt with oil pressure lower than I'd prefer, despite a fresh rebuild with bearing clearances. I used a standard oil pump when I built the engine in 2022. I didn't like the pressure but read about changing the...

Hey all trying to figure this issue out before I tear the motor back apart I'm getting oil out of the gauge port port but not enough to read any pressure. I'm using lucas sae30 break in oil with zddp not sure if that oil is too thick? I checked the oil pump and it seems fine. As a last...

So this past weekend I changed the pump for a stock volume and pressure pump and pick up tube. Cold start it goes to 40psi and hit idel it goes to 5psi. Barley registers on the factory gauge. Any ideas? Motor seems to run fine and no blue smoke from the exhaust. Bad bearing or oil galley plug?

Hi all, 1975 Fury 318 LA. around 50T on rebuild, Daily driver... I've been having an occasional lifter tick... Now that work is over for a couple of months I've decided to move on the project.. I pulled the valve cover on that side.. at first nothing seam out of order .. nothing way lose...

How long have you had the car? What is “This”? Oil level has nothing to do with voltage. Your car has an aftermarket volt meter ? You likely have a choke, or choke adjustment issue. Nothing to do with oil pressure. Could be a lot of things. Mostly tune up related. Unlikely unrelated to...
