Oil Leak - Pic - Name that part?

Maxhouse97 · 04-15-2008, 05:05 PM

The first pic is of the general area (not my car - ignore the arrows), and the second is a close up (sorry for the blurriness - your eyes probably hurt). On the first pic, the leaking part is top center - looks like an oil line (Duh)

. Pics are from the rear facing front - on the passenger side. Can you tell me what this line is and what parts I will have to buy to fix it? Is that line flexible or would I have to remove it entirely?

Wow that was quick - I love this place.

Mark, does this line lead from the oil tank or the oil cooler? I wouldn't have to buy a whole new line, would I? I know Pelican says you need a whole new line, but is there something I could try before dropping the cash on a new line? Any O-rings, washers involved between that fitting?

You could try some hi temp thread sealant tape and torque it down pretty good. If it's leaking on the back side of the fitting I think you're hosed though (pun intended).

OK that sounds like a good idea - I'll try it during my next oil change...

isnt that line a compression fitting? if you use sealant you may not get it tight enough to seal. i say just try tightening it, and clean it up. see if you dont fix it. if not, get a new line.

Yeah, it's compression. But if you don't use much it should be fine, just don't put more than one or two wraps on the threads.

sorry, i dont know plumbing stuff. i thought on a compresson fitting the threads dont seal. i was under the impression that the threads do nothing, but "compress" the ball thingy, into the cup thingy. i learned this under my kitchen sink. worth a try.

Don't try to seal the threads. The seal is made by the metal on metal under that nut where the lines meet. Sealing the threads will not help. It will probably stop leaking by tightening the nut. Make sure you backup the line (hold the hex on the hard line with a wrench).

You're right. But if the seal is leaking then "maybe" the thread tape will stop the leak from getting past the threads. Really just a fix until that stops working. Either way a new hose is in the future sometime.

I don't believe it is a true plumbing type compression fitting (heck, I don't know), but it does have threads for the nut.

Tony, in the book of receipts for work on your car, there is an entry that says the "threads were stripped" by previous shop or something like that in 2002 or 2004? It's a notation by the shop that did the Top End job, I think.

At the next oil change, I would try a couple of wraps of the High Temp Thread Sealant like equality72521 said to do. It's worth a try and it may save you $227.00 for the new part.

Thanks Jerry - I swear I will do a real "Here's my new 911" thread this weekend when I get a chance to take some nice pics.

Didn't want to use yours - that wouldn't be right.

It has been a while sense I did it but I think I used teflon tape on the seat, on the threads and at the top of the nut to stop the leak. Don't put any where it can get sucked into the motor.

Also---be carfull when tightening! It is easy to distrot these things with a normal wrench. I think there is a special wrench for these.

Maxhouse97 · 04-16-2008, 03:54 PM

Did you use regular teflon tape? I have that, but others have said to use the high temp stuff (which I was going to search for). If I can use teflon, I have that in the garage right now...

Here's another thing - as Jerry said, the threads are supposedly stripped. I am thinking I should not mess with it because chances are I am only going to make it worse - until I can buy a new line. The leak is very slow so its not a big deal - plus I have to save up for the Duck Tail!

When it comes time, would it be part #930-107-741-11-M20? Pelican says 87-89 turbo but does not list a standard Carrera. Oh and its only $99 (Cohline) as opposed to the Porsche one that is $694

Whats the difference between the two?

Tony, Is this the part you need? 911-107-741-17-M260 (for Carrera)???

Oooh, oooh a duct tail...be still my heart!

Maxhouse97 · 04-17-2008, 08:47 AM

According to Mark above, it is the engine block oil pressure line, which according to the Pelican link he provided, is part # 930-107-741-11-M20 (Cohline). The 911 part number is the OEM brand and is $695

. It looks like the right part according to the picture on the link provided by Pelican. But as I said before, I might get to it on my next oil change. Like you probably said to yourself, it hardly leaks at all, so it can go towards the bottom of the list in future repairs.
