Dennis,

The standpipe finally arrived at the dealer. I have it in my hand now, and looking at how it is assembled, the check valve within prevents oil from escaping from the center hole of the filter to within the engine, just as you described.

But if the oil enters the filter from the smaller outer holes, through the filter medium, and out the center hole, doesn't the standpipe checkvalve prevent fluid from flowing in that direction?

...my knowledge of this valve is purely anecdotal and based on my own observations, but I think the general idea is that it takes a slight pressure (probabably less than 1 or 2 psi) to unseat the valve so it does not impede regular pump flow, but the spring pressure is enough to keep oil from gravity-feeding out to the oil passages. I installed a similar (but higher flow) industrial check-valve in the "to-engine" line on my remote filter setup.

...Pierre, I just noticed in your original post that you use a 51773 WIX filter. I can't say I'm familiar with that P/N. Is it the smallish diameter one? I run a 51515 WIX on all my Mopars (they're all RWD, of course) no matter which motor. It is the big one.

51773 is the taller (2 quart?) version where as 51515 is the standard 1 qt version equivalent to fram PH8A. The filters are the same except the higher capacity one is taller. I believe the taller one is equivalent to fram PH977a? A while ago I heard someone on this board say they used the taller filters on the industrial slants and it provided for some added filtering capacity so that is what I have been running.

This is a picture of the bottom of the standpipe, the side that goes towards the oil pump.


There is a small plate of metal, with 3 slots in it. These are what the red arrows are pointing at. There is a spring directly behind the plate. So when you push on this plate, it moves up the standpipe, or into the filter. Thats why I think this valve is made so that oil comes into it from that side, but that would be the opposite of what actually happens.

Or, I could be wrong, maybe under pressure those slits let the oil pass into the engine just fine, but with no pressure the oil doesn't get past the slits.

I am not going to install it until I get some more info from other folks on here that have used a standpipe....

This pipe is chrysler number 3577848. That is what is listed in the 70-71 book as correct for a 1971 /6. There is another number, 2402607 listed for a 70 /6 but it shows no difference. Does anyone know the difference between the two?

Hey,

Dennis, do you use a universal remote filter kit, or some specific brand? I am curious about what experience people have had with them.

And another thing, the standpipe is only 2.5" long from the nut to the tip of the pipe, but the long oil filter I'm using is about 7" long. Is the 1970 standpipe longer perhaps, or should I switch back to the short filters?

Does anyone have an industrial slant parts book? I'd like to know if those standpipes were different then the car ones.

OK, I see now. Perhaps this is part of your problem?

Perhaps, but I'm not sure though because I only noticed this issue recently.

Pierre, I'm sitting here holding a standpipe... the plate in this one DEFINITELY moves down into the direction of the pump, the correct direction for oil flow into the engine. If yours is not like this, then I bet it is assembled incorrectly. The pipe is a press-fit into the fitting. pull it out and turn it around. Good catch!

I think PermaCool wuz the brand, I "enhanced" it a little bit for my purposes. Love it. No mess.

Dennis,

Just to verify, assuming the oil pump side of the pipe is towards you, the order of parts would be plate, spring, pipe, filter right?

How long is the pipe you have?

Negative. Looking "up" from the bottom side: Fitting, spring, plate, pipe.
huh-huh, huh-huh. Ten inches, dude...

OH, the filter standpipe! ...mehbee 1 and three-quarter inches?

Dennis,

Thanks boatloads for your help. This pipe is confirmed assembled backwards, because, as you see in the picture I posted, from the backside the plate comes first. Now to get this thing apart and swapped around....

I'm almost "this" close to scrapping this whole standpipe mumbojumbo and doing a remote kit as you did. Hmm, I wonder how easy it would be to get one of those kits locally

Argh, ok I tried to get the pipe apart but nothing worked. Gripping it with pliers, put it in a vice (vice was tight enough that it flatted out the pipe a little but the whole thing still turned when I put a crescent on the nut).

I'm at my wits end with it. I can either pound the valve out completely and use a hollow pipe, or try returning it. It was special orderd but since its deffective they may be nice about it....

Even with the plate in the right spot, it looks like it would restrict flow an awful lot.

Try stacking a couple of small hose clamps around the pipe portion tightly and use them to keep it from turning using them just snugged with a vice-grips, vice, whatever, then turn the fitting with a wrench...
