I keep blowing hoses to oil filter relocation?
Posted by kabobkebabkabob@reddit | projectcar | View on Reddit | 62 comments

I started with an eBay -10 AN hose kit for my oil filter relocation kit and after about 20-30 miles would blow a hose. Gave up on that and paid out the butt to have a hydraulic shop make me proper hoses. Those just blew out on me as well and they were rated to 1000psi.
My only theory is that I have had the hoses on in the wrong direction through the filter, though I have triple checked every time. My oil pressure sender is mounted to the filter housing and hasn't shown any spikes in pressure. 30-60psi consistently.
Could it be the shop just did a poor job crimping them as well? Any other reason this could be occurring that y'all can think of? It's the one issue plaguing my swap.

Is it getting caught on something? Roasted on something? Is the engine twisting and yanking on the lines? You say it blew out, how? Did it split the middle of the line or did a fitting fail? Can you show us how it's plumbed?
kabobkebabkabob@reddit (OP)
Fitting is failing in the same place each time. There should be plenty of slack for the engine twist.
Reddit-mods-R-mean@reddit
Do you have pictures of the failed line?
kabobkebabkabob@reddit (OP)
Both of them separated from the crimp. I think it may indeed be a tugging issue of some sort under torque
Present_Simple7162@reddit
Put a hose clamp on the hose.
Does your engine flop around at all? Are you're motor mounts good?
Reddit-mods-R-mean@reddit
Those are push locks right? I don’t see a crimp.
Push locks use a special push lock hose and although many people swear by them I have only ever used them for “no” pressure applications.
You could push that hose back on tight, butt the hose up against the ring on those fittings and use crimp rings.
You can buy a kit like this And crimp 2 rings on each fitting.
But honestly I would just go with PTFE hose and fittings. Beware you must use the proper fittings.
Here’s a chart showing the different hoses and fittings.
Remember to oil the hose before assembling or else they will lock up and could leak or break your fitting.

A hydraulic shop shouldn't build hoses for a low pressure application.
You can make your own. High pressure hydraulic fittings need high pressure to work correctly.
They slapped on the wrong fittings for your application. They will never carry the correct fittings. Make your own.
TheBupherNinja@reddit
Why not? Oil is oil, and high pressure hoses do low pressure just fine.
Reddit-mods-R-mean@reddit
That dudes a fucking moron.
NeedMoneyForTires@reddit
Go on then. Do it.
Reddit-mods-R-mean@reddit
I ran a an-10 1500psi hydraulic hose for a power steering return line for 6 years before replacing it.
Thing was twisted all though the engine bay, way to close to my exhaust and looped for good measure.
Never had a problem. You can’t explain why a high pressure hydro hose won’t work in a low pressure application because it’s total bullshit.
NeedMoneyForTires@reddit
You ran a AN line then. Not s high pressure hydraulic line. The material isn't what matters here. The FITTINGS. A hydraulic shop that work on excavators and suck will not have a double flare fitting, or a single flare, or an adapter to AN line. That's not what they do for money.
Reddit-mods-R-mean@reddit
Another swing and a miss.
I can’t believe I walked down ti my garage to check this hose.
You’re a waste of time.
I’ll admit I was wrong, it’s not an -10 it was -12. And it wasn’t 1500psi. It was 1900psi.
It’s a female RYCO JSEAL JIS -12 with a EN853 hose connected to AN -12 males.
Never Had A Problem.
Quit spreading misinformation

Janky? Lmfao. This is a photo you posted of your work.
GG troll.
Mr_Diesel13@reddit
Wooooooow 😂
NeedMoneyForTires@reddit
It doesn't leak, like OPs hydraulic line lol
Mr_Diesel13@reddit
I had a turbo oil drain line made at a hydraulic shop, and it’s fine. No leaks.
Your logic is flawed.
TheBupherNinja@reddit
Can you articulate what is wrong with using hydraulic hose for low pressure?
Temperature, absolutely. But if you get a propely temperature rated hose, what else?
NeedMoneyForTires@reddit
... the fittings? Bubble, flare, double flare, 37 degree. One of these are made for high pressure hydraulic applications.
TheBupherNinja@reddit
These aren't brake hoses. It's all AN/JIC/37 degree flare, regardless of the pressure. The 37 degree flare is standard (and the same) from 5 psi carb fuel fittings to 3000 psi hydraulic systems. You usually don't crimp low pressure hose, but crimps are better, no sure why you think that wouldn't seal 60 psi if it can seal 3000.
Again, can you articulate an actual problem.
NeedMoneyForTires@reddit
This works fine. Maybe I'm not a dumbfuck.
borkman2@reddit
God you're a twat.
TheBupherNinja@reddit
Wtf are you talking about, how is that relevant. Those aren't 37 degree flare fittings.
Hydraulic hoses are 37 degree flare. Most aftermarket automotive line sets are 37 degree flare. You can mix and match JIC, AN, 37 degree flare. Crimped or ferruled. Steel and aluminum. So long as the pressure doesn't exceed the lowest maximum, temp doesn't exceed the lowest *maximum, and there is no chemical incompatibility, it doesn't matter.
NeedMoneyForTires@reddit
Oh, most? So not all?
TheBupherNinja@reddit
Back to basics.
Why do you think a hydraulic hose won't work for engine oil.

NeedMoneyForTires@reddit
I bet 4 dollars your car leaks oil...
Reddit-mods-R-mean@reddit
No, but it does spit a lot of fire.
NeedMoneyForTires@reddit
K swaps, lq4 swaps, 2zz, you dont impress me with your over priced oil lines.
Reddit-mods-R-mean@reddit
My oil hose impressed your mom though, that’s what matters.
NeedMoneyForTires@reddit
When did I say hose?
I said fittings.
TheBupherNinja@reddit
Good job.
So, why do you think hydraulic 37 degree flare fittings can't seal engine oil.
TheBupherNinja@reddit
Alright, enjoy being an ignorant dumbfuck.
Sir_J15@reddit
Sounds like you have them routed wrong and the heat is causing them to fail. You aren’t pushing enough oil pressure to blow 1000psi hoses. You may also want to make sure those 1000psi hoses are at 250f and not at 70f. I have seen some hoses they use that are low temp only and at high temp they fail easily. Either it’s the wrong hose for the wrong application or it was manufactured wrong. I have had plenty of hydraulic hoses made and made them myself(used to make hydraulic hoses for fork lifts) and never had this issue.
donald7773@reddit
Also oil isn't hydraulic fluid. They may not like engine oil like many rubbers don't
sequentialaddition@reddit
How is it not? A lot of hydraulic systems use 10W or 15/40W.
donald7773@reddit
Engine oil?
sequentialaddition@reddit
Yes. CAT, John Deere, Oshkosh etc. all have equipment that uses those oils in their hydraulic systems.
donald7773@reddit
Cool! Learned something new today
Sir_J15@reddit
I haven’t came across any that that wasn’t compatible.
donald7773@reddit
Idk anything about hoses, I just know not all rubber is happy being covered in motor oil - just from my experience with coolant and charge pipes for example
Sir_J15@reddit
There are definitely some that if you are running ethanol and you are getting it in the oil it could slowly deteriorate the inside but outside something like that there isn’t much issue.
Sir_J15@reddit
Being a 3uz and that’s adapter you are using on the block it’s all in routing and slack/hose tension. I have a 3uz, similar oil filter adapter, 10an hoses, a Derale oil filter pedestal, and a remote oil cooler. These are not putting out enough pressure to blow your fittings. That aluminum adapter would blow off the block before you would blow apart a steel hydraulic hose. You have to route away from heat and you have to have slack so when stuff flexes it doesn’t pull tension on the fittings. Breaking fittings that’s your problem is tension. Out of the fitting adapter on the block, route line down under ac compressor(or area if you don’t have the compressor) and back up to an oil filter pedestal. There has to be slack in that line. I also have solid billet motor mounts so I know my engine isn’t pulling on hoses either and still gave slack.
kabobkebabkabob@reddit (OP)
This is my routing. It has slack and there's not much room to add more. They might be catching on the steering box since it crams very tight going around that. May have to try going over the box and under the AC compressor but idk
Sir_J15@reddit
Too stiff of hoses can lead to breaking of the fittings as well when you don’t have enough slack. Vibrations can as well. If they are catching on the steering box that can add issues as well. I would try rerouting. Also look into PushLok hoses. They are more flexible so they can help with that as well. Most are good to around 300psi and hot oil resistance too.

I don’t know, but I want to know more about both vehicles.
boostedmike1@reddit
I’d be replacing the filter housing at this point must have a huge restriction in it

Did you recently buy that Trooper in bringatrailer.com?

Nah

I have broken a lot of hydraulic hoses at the fittings before but I’m usually using them for hydraulic applications.
Even though these high pressure hoses can be more durable they are easy to over tighten and break at the fitting.
I have also broken several fittings on hydraulic hoses trying to tighten them with the hose angled incorrectly. You will usually notice the hose start to spin with the fitting before it is tight when this happens, but not always.
Hydraulic hoses are also built with several types of fittings and it could be the nipple/house fitting combination you’re using don’t like to be combined. Flared fittings, pipe fittings, and o ring face seal fittings don’t always play nice together.
Say_My_Name_Son@reddit
Okay, good info. What filter are you using on the Earl's mount?
TheBupherNinja@reddit
Do you have pictures of the failed parts?
Paper-street-garage@reddit
Bad pcv? Too much crank case pressure? Too much oil pressure?
Big_Gouf@reddit
Is the hose splitting, or are the fittings leaking? If the fittings, is it at the same place every time? Could the filter housing be faulty?
kabobkebabkabob@reddit (OP)
The fittings are separating
shopboss1@reddit
Use constant torque clamps.
Sir_J15@reddit
Common with eBay AN hoses. Cheap low quality knock off. Never are what they are rated too.
Erection_unrelated@reddit
It’s possibly you got two faulty hoses, but I’m skeptical… especially since you had a shop make you a hydraulic hose. Those things are made to withstand so much more pressure than a car’s oil pump can generate that it shouldn’t be the failure point.
I’d look at your routing. Is the hose near a heat source, like the exhaust manifold?
