Yeah…. If I had one. Mopar Action had an article years back…Ehrenberg had two AA batteries in series he used to test gauges. I can’t find any damaged wires. I pulled the bulkhead plugs and cleaned them with DeOxit and a wire brush. They got blown out and filled with dielectric grease. No...

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

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

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...

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...

Recently my 200,000 Grand Cheeroke lost nearly all its oil pressure. Read 6 psi on the gauge. Sounded fine. Towed it home. The 3.6 engine uses a cartridge style filter, so it makes inspection easy. Pulled the filter to inspect for debris in case there was engine damage. Zero debris, but it...

I "think" it is there but won't know until I pull the pan which I am not looking forward too, its a pretty tight fit.

Probably wouldn't run it if it was an actual airplane!? Bunching up a car motor is one thing.. aero not so cool

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...

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...

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...

I run VR1 straight 30 in the winter and straight 40 in the summer in my 400 with 140k miles, it likes it. No cold start issues, builds 80 pounds idling cold and 20 idling hot. From my experience 10w30 is too thin for a stock big block, the oil pressure drops to 0 on hard launches when it's too...

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...

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...

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...

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

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...

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...

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...
