What is this leaking line?

[dan79brooklyn]

I noticed this leaking line on the engine when I was in the middle of another project.
I know I need to address this leak shortly..Does anyone know this part no.?

Is it easy to replace?

[Don Plumley]

Looks like the clutch slave flex line. Not too bad to replace - go ahead and replace the clutch slave cylinder while you are in there and flush the system.

I don't think that line is part of the clutch system. It was leaking motor oil. I will have to look at a parts diagram and get under there again.

I am not losing any blue brake fluid.

Thanks for your help though, I'm sorry for the bad pic. The line looked like it ran from one part of the engine to another...

I have to agree with Don, let us know what you find.

That kind of leak will take you years to lose enough brake fluid to notice. I've never seen an oil line with a fitting like that, but I've seen plenty of clutch and brake fluid lines that look identical. That's not motor oil. It's just that your brake fluid is so filthy that it looks like motor oil. Have done this job several times.

I agree, this is the clutch line

Don't argue with Don until you have about 5,000 more posts. If ya know what I mean...

I just did a clutch replace and saw the exact same picture. You will want to raise the rear of your car as high as you can, remove the shift shaft, and drop the transmission about 6-8" in order to remove the clutch slave cylinder. It comes off the transmission easily using a 13mm socket on each of the two nuts. Pinch off the brake fluid reservoir line that goes down to your clutch pedal master cylinder. Then break the connection that is leaking and remove the old hose. The P/N is 964-423-477-00 and it is about $40 from our host.

Remove the bleeder and clean out the slave cylinder by flushing it with fresh brake fluid on the bench. Attach the new hose and get it tight, then fill the slave cylinder with fluid before you reinstall it in the car. Clean the fittings, re-install the bleeder, and connect the slave cylinder and hose assembly to the hard hydraulic line on the car. Un-pinch the line under the brake reservoir and bleed the entire clutch hydraulic system with a pressure bleeder. Bleed the air from the slave cylinder in all positions before you reinstall it on the transmission by tapping it with a hammer. Ensure the slave cylinder operating rod is aligned with the clutch fork before you attach and tighten the mounting nuts. Then lower your car.

Good Luck,
Mark

Hi Mark,

Thanks for your detailed description.

It's good to know of the job ahead for me.

I'm dealing with some ignition issues at the moment, but I hope to tackle this clutch line in the near future (springtime if I'm lucky).

Best,

Dan

Thanks to Don Plumley for the correct diagnosis with his original post.
