Alright, I tried looking in the forums for more info and apologize if a thread already exists on this, but have been stumped. The 340 in my car has 60+lbs of oil pressure on cold start and maintains about 35-50lbs on the highway, but low rpm and idle after warm it drops below 20lbs. No knocks or...

I have an aftermarket mechanical oil pressure gauge under the dash on my car. It is fed by a straight copper tube. When the engine is idling, the needle bounces all over the place. I have another oil-filled gauge under the hood that registers 70 psi, with no bouncing. Do I need to put a couple...

He's giving us oil pressure numbers, does the stock gauge do that? I have used an oil pump gasket on a small block, or not, no change in oil pressure, for me.

71-74 rallye dash no numbers just hashes if memory serves me

It’s a Dakota digital dash, so looks stock but does have a digital output to show metrics.

Hey guys, I just got a "new" to me 1968 Charger with a "rebuilt" 383. Come to find out the guy I got it from had 0 idea on how to build the car and did a lot of things very half assed. The oil pressure gauge in the car doesn't work so hooked a mechanical gauge to it. I think the car sat for...

This is a Used Oil Pressure Gauge Sending Unit. It is for a oil pressure gauge, not a idiot light. I can no longer remember what year or model this one came out of, but I'm sure it worked or I wouldn't have saved it. $15.00. Local pickup, or buyer pays shipping.

I just put 10w-30 in my 1969 383. I’m not sure what oil was in it before but I didn’t seem to have any issues. I hooked a mechanical gauge up and the line filled with oil and held 75 at cold temps. However, when the engine is cold now at idle I hold 28 pounds and the oil line to the gauge won’t...

What we’re working soon.. it’s got a bad oil pump. It cranks but the valves are clacking showing no oil pressure.. and it’s got metal shavings in engine.. so where going to pull and rebuild it.. give me something new to drive.. 5.7 Hemi..

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.

...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.

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...

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

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...

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...

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...
