Yea that is inside the 2” bend radius…

I believe it is brazed into a fitting boss…

I actually had that happen on a turbo oil line… WTH I know I tightened that fitting! Another fix is to deform the line loop slightly in the loosening direction as you tighten the fitting so the natural shape of the loop is then always applying force in the tightening direction…

You could use a rubber or foam mounted, or even stuffed in between the hoop in the tube and the head, but the flexibility of the rubber/foam would have to exceed the ammount of potential energy of the tube hoop when a vibration force is applied to it, so it can’t move. You actually want the...

I am sure tying the center of the hoop to a bracket attached to the block would fix it. Every pic of a broken one I have seen has broken right where the tube is welded to the fitting boss. This is what indicates vibration to me, if it were some other cause they would break in different places...

Even for that type line, which is a little more forgiving of bend radius, it is still closing in on the minimum bend radius. Most of the teflon ones I see being installed are well under the min bend radius. 2” radius means it has to go around the outside of a 4” piece of pipe… thats why I...

A false alarm is not such a big deal especially if I know I am not level. They are typically placed out over the deep part of the pan sump, at about the height of the raised bottom. This pan doesn’t have a very deep sump, but if my measurments are correct the pan is normally nearly full, so if...

Along the lines of an oil level sensor, up to 96 ford mustangs used them, and a lot of GM/chevy’s use them. The fords are $60-100 bucks and the GM’s are in the $20 range. I don’t recall the ford thread spec, but the GM’s use a M20X1.5 thread. They are installed in the side of the pan at a...

The problem wasn't that it was a steel line, there are other steel and oil hard-lines on the truck and they don’t seem to break. these lines should last forever, especially considering these trucks don’t have hundreds of thousands of miles on them… The problem was the application. All those...

Perhaps more effective would be a low oil level sw in the sump wall to tell you the pan is low before the pump looses suction. Pretty common low cost item that works great on pressure washers and other power equipment. would turn something like this into a non event…

Cool, keep an eye out for it though, we had one guy break one, replaced it with the cat part and turned right around and had that one fail not too long after. it is an overhung part without support and will tend to oscillate if any vibration is put into it… like a diving board…

I don’t think it is fatal, as when it fails you loose HEUI pressure pretty quickly and the engine quits running:)

The issue with these teflon hoses is their bend radius. Take a plastic drinking straw and try and bend it. The thin wall teflon liner behaves a lot like this and will want to collapse. The braided sheath helps to prevent this but it has limitations to about a 2” radius... because of the...

Vibration isn't necessarily a problem as long as all the parts move together. I believe it is the independent movement that is killing this hardline. This horseshoe shaped line creates an overhung mass like a diving board. If that mass at the end of the diving board can move independent of the...

I don't think the flex line will appreciably change oil pressure or flow as long as the bend radius is not too tight... Once the O-rings are under compression, I don't see them offering much dampening surrounded by the rigid fitting. Corrosion on the pipe could be a weakening issue, the heat...

Anything that changes the mass and makes it less resonant at whatever input is causing it to work and break would probably work. Clamping it along its length effectively adds the mass of the engine to it, and it also divides it into two components at a different, hopefully less resonant length...

The length of the line could also be a factor. There are other hard lines on this motor, and they don't seem to break. The size(and shape) of this line may make it susceptible to a particular frequency. A clamp to the head mid-span would help to dampen these. There are however a lot of these...
