Crushed oil line

[targabill]

Pretty common to see a crushed oil line right behind the Right front tire. Mine spring a leak there.. Has anybody tried to splice in a piece od 3/4 copper line which seam to be the same O.D. as the brass line. I was thinking of two 3/4 Flare Unions, but only seem to find one that work up to 5/8 copper..

I just cringe at spending $800+ for the hard oil line...
Maybe 2 pieces of rubber hose and clamps? Hard to find oil compatible rubber hose that's 7/8 ID..

Ideas?
I feel like soldering this would be risky??

I wouldn't take the chance with rubber hose and clamps.

If you remove the oil line (probably the hardest part of the job), use the air pressure method to fix the dent. Then braze the hole.

I think I would try this route. If it doesn't work, replace the line.

It can be fixed with silicon bronze. Buy one of those little bernzomatic torch kits or take it to a welder.

My car had a brass plumbing piece spliced in when I bought the lines. Worked fine for years. Don't see any downside.

I ditched the dealer installed AC when I inherited my dad's 74. Chuck sold me a set of "Take offs" from one of his finned oil line installs. Forgot the price but even with shipping it was reasonable 12-13 years ago.

Former master plumber here- I have used 50-50 solder and a plumbing torch on ordinary plumbing fittings to repair a long oil line without issues

Thanks everybody!!!

Does anybody know what kind of pressure is in these oil lines and the trombone up front??

Very little. The lines don't see engine oil pressure.

I know someone with a broken oil line. He cut out the crushed/cracked section, replaced with rubber hose, and generic hose clamps.

So far, it seals and works and doesnt leak. Not what I would do but if it works, why not...
He is a pensioner on a budget so was reluctant to buy new hard lines understandably.

I got new oil lines from The Parter Geeker folks. Was surprised at the prices and quality. On the car not and working just fine, as I finish up my rust repair. Car has AN-12 lines before, brain dead.

I soldered in 3/4" copper no problem. That was in 2008. But i removed the lines to do it and that is the sketchiest part because they often strip the threads off the thermostat from corrosion. So first I guess I would try to solder them on the car. Maybe just removing from the front and all the clamps to lower them down. Let them drain a few days and try to swab out as much oil as you can to prevent contamination.
