How do you fix an oil line?
What oil line is this ? If you want help you will need to be a little more informative . But if you are asking on the web a shop might be the best thing for you to do .
It has an oil cooler? Or is it the transmission fluid line? I’ve used fuel line hose double clamped for a low pressure transmission line, but if high pressure, needs to be replaced.
With tools. If you will give more detail, so will I.
I’ve seen guys do that and really regret it later on . . . I consider such a repair nothing more than a roadside band-aid
