...I had it ready to fire up today. My buddy and I worked on it Saturday and today and got the 440 engine running, only to find we had no oil pressure. I had tried priming it with my power drill, and foiund it only had a slight resistance when spinning CCW, and none when spinning CW. I know the...

I think the answer to your question is no. The priming oil pressure will not reflect operating oil pressure, if that is your question.

Doesn’t the breather exhaust to the air cleaner, under positive pressure versus a vacuum on the PCV. I would think the breather has more chance of getting oil vapors into the air cleaner. This is what I needed to know as well. If they fail open, then I don’t need cold start warm up, but I do...

Hi guys. Have another build on the go. This time a 360 LA 72 block. Without all the details, some brief history is as follows. 10.5:1 KB, all new and machined parts. Block is one that I've had kicking around for some 10+ years. Originally it had 8:1 and mild cam. Was a short block for sure as...

Had similar issues ..... but my engine was Dyno run .... so I thought it was ready to go. When I started it there was a delay of pressure to reach the mechanical gauge but had good pressure. First power run ....gauge went to Zero. Shut engine off on a 4th to 3rd power shift ... got good...

EDIT for correction - no vent holes under cap - On mine I've got a valve cover PCV valve cap like this (with a vacuum hose connecting the PCV 90-degree nipple to manifold vacuum): Compared to this, what's the added benefit of placing the breather on one valve cover and the PCV valve on the...

When I saw this, I just had to relate what happened to me back in 1968 with my first car, a 1964 Dodge Polara with the slant 6. A bunch of us guys (we were all teenagers back then) were driving to a remote town about an hour away in a dense fog in the middle of the night. Half way there I...

Up for sale is a New Mopar Performance oil pump. Part number is P4286590. Application is for a big block. High volume regular pressure. No attempt was made to install it. Includes gasket & O-ring. $75 + $20 shipping in the 48 states...

Engine bay is kinda busy looking, but no way around it. I'll work on getting it neater after it's running. Next is to crank it over to check for spark, then reprime the oil pump and check oil pressure. Also install new valve cover gaskets & hardware

I’m not trying to be a ********, but you didn’t learn about the importance of a working oil pressure gage.

Got Fuel Tank plumbed and got Fuel gauge working. Let the Charger run for 20+ minutes today! Good oil pressure and got it up to temp with no leaks. Alternator seems to be charging. Ready to pull out of shop!

I have been installing oil accumulators on my performance engines/engines that can sit for months without running. Mike

I used a sealer on mine and I have to say that I really screwed up by doing that. It looked great at first, all shiny over the burnished and light gray dyed concrete. The problem is that oil etc gets through the sealer and than you can't get the oil stain out. I should have used some sort of...

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...
