This was done by the PO, apparently not wanting to deal with the lifting of the engine and all that when doing the lines... It has worked fine for me ever since I bought the car with no leaks, and when I do get leaks I only have to buy a bit of hose and clamp it back in... I'd like to hear your opinions on what do you think the pros and cons of this rig are.

Without some form of hose retention other than a clamp there is risk. Even a ferrule soldered on with the rubber hose going on past it is some help. That is with a clamp on the portion past the ferrule.

Many may not be aware that there is also a screw clamp that has brutal compression in comparison to the standard screw clamps. They are used on silicone coolant hoses.Normal clamps are not good enough for silicone hose.

Again though a ferrrule should be soldered on to prevent any possibility of slippage even with those.

there is a long thread floating around where a whole bunch of people did this and it worked out fine. As it turns out the metal parts are barbed underneath the rubber hose. The consensus was put 2 hose clamps on tight on both ends (4 hose clamps total) and you'll be fine. Just make sure the hose your suing is rated for use with an oil cooler.

Well, since you asked for opinions, I would be scared with that arrangement. It looks like a couple of the joints are leaking. I would take them out and down to a hydraulic hose shop and have them press new hoses on with metal sleeves or ferrules. If you are worried about ruining the oil cooler, then leave them connected to the oil cooler and take out the oil cooler leaving the both cooling hoses attached and take it down to the hose shop.

I found that it was diesel911 who did this and worked fine for him... I checked my hoses for the first time about year and a half ago after seeing the dieselgiant website. I admit I got a bit worried to be driving around with such contraption in my cooler hoses, but decided to give it a chance. It has worked fine since. I see that the one of my hoses is getting a bit oily so it's probably time to get a new length of hose and crimp it in, but I think it's a safe and economical alternative to changing the whole lines, besides being a lot easier.
Thanks Whunter for those oil lines threads, I spent an hour or so going through them. Very good read.

Cirrusman,

Anything other than Hydraulic Crimped Fittings
(With appropriate High Temp and High Pressure Oil Lines)
Is just spitting in His Honor, Lord Murphy's face.

I will not even use the "Double SS Hose Clamped" folderol on the boat fittings
(And that's only Sea Water @ Ambient temps with less than 1 bar of pressure.)

At a minimum, use the clamps that Barry refers to. They're called constant tension clamps or something like that. 80 Series Landcruiser owners use those clamps on the PHH hose because they are much more secure.

You can see pictures of the clamps here.. They are Breeze constant torque clamps.

Ahh, as long as the job holds more power to ya.

But for my anxiety, the thought of being stranded is enough for me to pay for the full price for new hoses and do the job correctly.

check out what the PO did on mine. Removable hydraulic hoses, I was extremely pleased to see this.

It looks like mine do right down to the double Clamps on each hose end.
If the Clamps are tight I find it hard to believe that a hose would slip out from under 2 clamps.
Also on my Oil Cooler Line Tubings the Jags on the very end of the Tubings are larger than the rest.

I'd suggest making the following changes:

Take the hoses off, degrease, apply crazy glue, put hoses back on and and use 2 constant tension clamps.
