Has anybody tried to change the right side oil lines on a turbo body 85 911 that has rear brake vents that block access to where they connect to the thermostat?

I recall the ducting has to come out, but it has been a while.


I opened a post in our forums. A Pelican community member may be able to answer your question.

Yes! Simply put.. they're a Beyatch!!

If you have tried already and you're having issues, don't worry about...you will. However, it is doable.

As usual, soak the connections with a good penetrating oil. To the rear, you'll have to disconnect the clamp in the wheel well, and the clamps that run down the rocker panel. Also disconnect the hoop clamp in the front wheel well.
You will have to gently spread the 1/4 away from the tub as you pull down on the lines to get them to clear the brake vent. Install in the reverse manner.

Once down you may need some help breaking the lines loose from the thermostat. As this connection is normally tough, it may be even more so as being lowered out of the car you really have no leverage.

Regards and good luck,

Just went through this on my 930. Since the vents were one-piece and permanent, I considered cutting the vent box off on the inside, and then re-attaching it using metal straps. I finally got lucky using my 36mm wrench, that flat 36mm line wrench; the one that's made out of flat stock, and a pair of channel locks. One line is definitely in the way of the other. I'd get the easier one off first. I'm still debating cutting the box and making a couple of straps that will screw in place to re-attach it. I feel your pain. This is a real pita job. I believe my channel locks finally got the job done. Hang in there, you'll get it.

Take the lines and thermostat out and do it on the floor

OMG just did this twice in a week. Second time was today due to leak at the thermostat. Apparently i did not tighten it enough. Basically i decided there was no way I could do it with the lines mounted so i took them out. This was my procedure:

1 Empty oil tank
2 remove front and rear tires on the passenger side
3 loosen the connection at the engine hard oil line- be prepared to catch oil
4 loosen the connection at the oil tank- be prepared to catch oil
5 cover the front passenger brake and rotor with a plastic bag
6 loosen the connections to the front oil cooler. In my car they are passenger front tire area- be prepared to catch oil
7 get a friend to help you out as you remove the oil line supports
8 work the lines until you get them out from under the car
9 I was only removing the line to the engine so I left the other one intact
10 used a dremel to cut most of the way through the nut and used an adjustable wrench. It came off with some effort but without too much drama.
11 applied antiseize
12 installed new line
13 have the helper hold the line as you tighten it down.
14 reverse to install the lines

Notes: the lines are 36mm; i had a scissor lift which helped alot; the rear support of my lift at first interfered with getting the line out; i have the boxed rockers in my car; the plastic bag in step 5 is to keep oil from falling on your brakes; expect oil out of the lines and be prepared for a minor oil mess.

Again, I highly suggest a helper to maneuver the lines in and out.

Thanks for all the helpful ideas. I was considering finding a coupler and cutting off the flex part where its leaking from. I am starting to realize that most stuff on this car is hard to fix.

If you post photos of what is needed perhaps I can help.

I am a dealer for Cohline in Germany, and have a bit of experience with Porsche fuel & oil lines & hoses, and make a lot of custom stuff.

I cut the ducts out and I'm going to shut that vent opening, it makes my life easier in the long run.

[BoxsterGT]

Here is one option the factory used with brake ducts in the way of the hoses & hardlines.....



The thermostat is re-located next to the oil tank and gives more room for the ducts.

I found this posted by a fellow Pelican a long while back. Wish I knew how the rest of the system looks.
