repairing a LEAKING “banjo bolt” (fuel line, brake line)

- These banjo bolts could be a real pain to get to reseal. It seems like everything‘s gonna be perfect. In this video I’ll show you how to use sandpaper and symmetrically cleanse the surfaces so everything will fit nice even in tight
No expensive laser printer needed: I cut a hole in 1000 grit sandpaper by using the ID of the copper washer as a guide and scoring the sandpaper with an exacto knife, yeah thats right no $1000 laser was needed. I then sanded the banjo bolt perfectly smooth with no problem pressing down the sandpaper with one of the copper washers on top. This did not end the leak although all surfaces were cleaned very thorouhly, but the fitting still leaked. I finally solved the leak problem by ordering a set of Stat-O-Seal washers. I have no endorsement by Stat-O-Seal or anyone else. All you need to know is the ID of your copper washers before you order.
1:37 this is what helped me the most! THANK YOU!!!!!!!!!!!!!!!
Will your next video be about troubleshooting a car that doesn't start?
Cool video, I liked the sanding method. I was doing it freehand and probably messing my parts up. Just wanted to say that you made a mistake on the part about annealing copper. Copper must be rapidly quenched to anneal. Heat it up past color change and plunge into water. It’s the opposite of ferrous alloys that are heated and slow cooled to soften.
Nope. Copper can cool down either way and still be annealed. It just is not like iron/steel.
It need only be heated past its transition temperature -- which is red hot.
This color will appear out of 'the black.' So, keep heating when the copper merely looks black.
instead of doing all that unnecessary work, simply heat the copper washer until it becomes malleable, it will fill all gaps and imperfections when tightened down. Work smarter not harder
thanks for the tip, will try this later once i take everything apart again
I have a 3D printer, now I need a laser! Good thing you did making it clear the reheated copper does NOT get quenched because so much online friendly advice goes into arguments about their favourite way to quench them with water or oil SMH.
Did that engine ever start up? :) The ending was like the operation was a success but the patient died.
Now all I have to do is get it started thanks for the help
Try tightening the bolt, then tap with hammer, you'll find that you can tighten a lot more after. Repeat process till you're happy with results. Cheers.
Removing material can affect the dimensions of the final assembly. Many banjo fittings must maintain original dimensions or the seal will be unreliable, or worse, the banjo can strip out the threads of the components. Ask me how I know😟
That only happens if you don't torque things to the right spec bro and if you take off way to much material.. either way it is fixable
Thank you for the informative film. But how do you know if those holes
(in the hose and in the banjo bolt) are lined up? Are you supposed to
use some marks on the top of the bolt? Because you torque the bolt and
maybe it should be turn a bit more to be aligned?
Theres a groove on the inside of the banjo, so the fuel can get to the hole no matter what angle it is at.
@@roshtilden4463 Thank you very much for the detailed explanation. I knew already that there is some space on the banjo bolt through which the liquid can go regardless the angle, but I didn't know that the void is shaped as a grove. I'll look on a banjo bolt where is it. I changed already 4 banjos, but as a beginning DIY always try to understand all the details. Thank you again.
Great idea.
👍👍
you went through all that and reused the copper crush washers? and that bottle has had it too. replace both of em.
The problem was those washers didn't crush in the first place.
If you strip the bolt or the inside what would you do so you make it tight?
Do the holes in the banjo fitting have to line up? I have one on my turbo for a coolant line. Not sure if I have to line the hole in the bolt up with the flow of the pipe.
Doesn't need to be, The banjo is kind of hollow all of the way around, it has a fat groove in it so that the fuel or brake fluid will find the hole no matter what.
Thx for clearing this out. Wasted time last time when fixing car breakes and lined it up with great effort. This time i tried to find info about this topic since i need to change new brake hose. I looked my new parts and clearly there is a room around those main liningholes so it won't matter if banjos are lined up or not.
How did you verify the hole was lined up with the fitting?

And it doesn’t Start 😂
HELLO I NEED HELP WITH MY M BANJO BOLT, DO YOU SERVICE OR HAVE YOUR BUSINESS I CAN SEND TO
The cacth is having the hole on the inside of the brake hose On The Fucking Top!
