STP, Lucas and similar products are viscosity index improvers meant to guard against oil shear breakdown. Really important since anything with sprockets and chains has to deal with oil shear. The days of using one oil in your daily, hot rod, lawn mower etc. are long gone. My suggestion is to...

I ran into that situation on a 350 SBC ages ago. 10/10 crank, std bearings. Ran perfect, no noise at all. Normal-ish oil pressure on cold start, very very low pressure when warm.

If you are getting over 50 psi oil pressure now then maybe the oil pressure problem is fixed. But I'm still not convinced you are setting the valves properly. You and I would think if you set the valves at TDC firing then the valves would be closed so that's fine right? No, that's not how you...

Air is drawn IN through the breather. Air is drawn OUT through the PCV by manifold vacuum. Since much of the crankcase volume is from blowby, just how much air is drawn through the breather is questionable. More often than not there is oil spray around the breather which would indicate there is...

I'm running a rebuilt oil pump, stock replacement Melling parts, on my 440. When hot, oil pressure is around 13psi. It will hit 55psi when romping on it. No issues, no clattering. Deep sump pan with 10w-30. Never had the oil light even flicker, even when racing it.

...3.5 screen is working (they are on the same cable). 5. It doesn't stay running for more than a 30-45 seconds. 6. Biggest issue; NO OIL PRESSURE... this is a brand new crate engine so I believe that its not a mechanical issue per se. I am running a remote oil filter and I removed that and...

...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...

Too high? Cold, no. What is warm idle pressure/45mph pressure? I like a 40-45lb idle warm, and 60-65 down the road. 75 at road speed wouldn't bother me. That looks to be about a 7-8qt pan (+filter). I'd run 7qts, including filter. I would absolutely ignore the fill line on the dipstick. The...

Hmm, never heard of the Gibbs before, but, I'll be happy to look into it. Being in PA, which the summers can get quite warm, I'm leaning towards 5 quarts of the 10w-30 (and no Lucas additive). Seeing how I probably should use conventional vs. synthetic blend products, such as the Brad Penn /...

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 "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.

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...
