YES I've had a bad Wix 51515, no oil pressure, car was fine with a different filter. I never fill filters, done thousands of oil changes. No need, waste of time and maybe spilling oil. And where do you fill it, right down the center hole? That's when the clean oil comes out, not where the oil...

If the lifter popped out, there goes all the oil pressure to pump up the other lifters. Take a look down in there.

I changed the oil and filter on my 440, recent build with a new pump, Wix filter. Started it up, no oil pressure. Scared the crap out of me, pulled the filter, pulled the pump. Couldn’t find anything wrong, got out another filter, half- filled it with oil, put it all back together, started up...

Yes of course they aren't contributing to thrust but they are bearings under load with no oil pressure during initial cranking just the same.

It could still be a lifter if the oil gallery ports have build-up. No oil pressure= tick. You did say it was used but we have no idea of the condition. Also after replacement you need to follow the same break in procedure as with a new camshaft. You may just need to run it faster to pump up...

Low oil pressure on a hot engine at idle is a pretty common indicator of wear, but nothing to be concerned about, unless you're expecting a freshly rebuilt engine. By 2000 RPM, I want to see it up there in the >60# area, but we can only work with what we have. I've got 440 HP that only hits...

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...

Had that happen to me. Took off oil filter and screwed around for half hour or so. Filled filter half full put it on fired it up no oil pressure. Had to remove pump and white lube it. Now no screwing around once filter comes off.

Someone on here made a comment about a mounting gasket being made with the wrong hole alignment. They had pictures of the wrong holes affecting oil pressure.

My experience with the stuck bypass valve was the result of a very small metal shaving getting wedged between the pump body and the valve……. Resulting in it being stuck in the fully closed position. This was a 340 with a Melling M72HV pump. The result of that was a hot idle oil pressure of about...

eck.. i didn't see the PSI part in the post... yeah that's bad... sorry :( i need to stop posting. :)

Dipstick, I don't even know if my 2019 V6 Durango has a Dipstick. It just turn over to 22,000 miles on it and had its first oil change at 500 miles like I've done with every new car I've ever owned. It's had 6 oil changes in 22,000, besides the first one. If it can't last that long without...

I think it has been a combination of things. 1st of course is the imported lifters and cams. 2nd is high spring pressure on the crap lifters and cams. 3rd is the changes in oil chemistry. So many things have changed since I was a kid, Heck we used to swap cams and lifters and drive away, no...

Or I changed mine 3x once and last time believe it or not my valve cover breather was plugged ( thought I had clean one from because at the time there was was no resto ones available and had a newer Mopar high domed chrome one on with chrome valve covers and during resto of the car put all my...

True - I used the wrong word. I should have said there is no supply of oil to the bearing from the oil pump, so what oil is there has no pressure behind it and little ability to keep the two from touching.

So five main bearings, each with an area about twice the size of the thrust surface... Add to the they are horizontal surfaces where oil with tend to puddle whereas the thrust surface is vertical and tends to shed oil... Enough already, you do you, I'll continue to put my manual trans in...

FWIW, mine was on my '77 360 Ramcharger daily driver way back, early '80s. One cold morning I started it up and seemed fine. As it warmed up the oil pressure dropped off considerably. Shut it down checked oil level which was fine and no shiny particles on the stick. Restarted and pressure came...

Last year I dealt with the dreaded rear main seal leak on my coronets 318. After trying four different seals I was able to stop the leak. A couple of weeks ago I noticed a drop of oil at the bottom of the bell housing and panicked! I removed the transmission inspection port and no oil buildup...

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.

I have to agree with Dwayne that if the relief valve is completly bottomed I've seen close to 200psi. Install the cup backwards in a small block and see what happens. My belief is that some oil is always bypassing. But by the time that there is a spring that holds the valve that far bottomed...
