And there was no obvious cause. So far everything that’s been leaky I’ve been fixing was the result of loose bolts. No one has bothered to go over this motor in a very long time it appears and suddenly I start driving it often. Now I have lots of fail points to run down. Oil pressure while...

Why does it need more oil pressure? He has 70-80 at cold idle, is that to low, because it too will be going up a lot with 50w oil. How is more oil pressure going to cool the valve springs at idle? Flow provides more cooling, pressure is resistance to flow. Thicker oil doesn't flow as much as...

If you had no air bubbles what makes you believe you had air up top? You mentioned having the cam blocking air to the top.... The oil pump is what's referred to as a "positive displacement pump" which means if it's turning it will displace oil... But if it's not turning it acts as a blockage...

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...

I asked him about the motor break in back then and turns out he worked for Oldsmobile first in the mid to late 50's and said they built the engines on the main line with no separate engine assembly plant and the engines were on their own stand and he and several guys like him had test run stands...

I had that problem once except it was on a Hemi so there is no valley pan. It was just impossible for oil to get there. There is no place for oil to come out of that would end up there. It was impossible. After several months I finally figured it out. I had a different problem causing big time...

In my experience, lifter bore clearance bleeds more oil than large bearing clarances. You have proven what those in the know have said. Relief spring pressure has nothing to do with idle pressure. You've also learned that water temp and oil temp take two very different time lines to achive. The...

There is a small pump (I believe it's a 4 lobe epitrochiod type, similar to the engine's oil pump) mounted on the back of the housing, driven by the compressor's crankshaft....perhaps your pump was inoperative or it's oil pickup tube was blocked. The pressure switch should have prevented the...

He's a little concerned and would like a little more hot idling oil pressure. No big deal, a lot of people are like that. It won't go up at cold idle with thicker oil because the M-63HV bypasses at around 75 psi. That's why he has 70-80 now.

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...

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

Ohh..well as I had the pan off, I just did pressure going into the oil galleys from the bottom? I was getting air up top. Thats when I ran the camera into the right water bank looking for air bubbles with soap water and WD and I found no leaks there. Now that won't get me to the web, but...

Ok, I very carefully installed my wire set-up on my 727, making sure the hole on the carb lever was exactly where it should be (I took the special mopar bouchillion throttle plate to double check with.) I tested several arms (Different lengths) down on the throttle lever on the 727. I got a...

Hey all, so yesterday I was tearing apart my 383 from 69. Since it lost oil pressure last year and while I was tearing it down, I found that some of the very outer edges of the cam lobes were pretty jagged but all the lifters looked in good shape and the lobes themselves looked fine as well. I...

I still say everything could be fine. When people get low hot oil pressure they think they have a "bad" oil pump. No. These oil pumps almost never give it up. I started a 55 year old Road Runner with the original oil pump a few months ago. The pressure relief was stuck. I don't know how much oil...

Evening All Nearing completion of my 67 gtx restoration and have run into a problem with the oil pressure warning light. I have put an original 426 Hemi 4 speed into my gtx, an original 440 car. Purchased all new m&h hemi underdash, front engine/light harnesses and positive battery cables. The...

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

the 69 and earlier cars do not have a low pressure cut out switch. The compressor does have it's own "pump" and I believe that is for oiling the crank, the top end (pistons & rods) will not be lubricated unless the system is charged. Mine was a completely rebuilt unit by an experienced shop and...

I like to move the push rod up and down and gently tighten the adjuster till there is no more movement. I find with the spin technique its possible to start depressing the lifter plunger. Most adjusters are 24 threads per inch. So 1/2 turn gives .021 and 3/4 turn gives .031. I have adjustable...

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.
