I don't think the marks will be a problem, it will probably seal up.

Ill send a pic after I smooth it out.

Then lmk your thoughts.

The outer edge does not make the seal, it is in the center where you can see a "ring" around the surface in the photos on post #17. The ball or globe surface of the female hose fitting seals against this.

In severe cases, a soft copper insert like this.........

can be used. Its soft enough to conform to the surface and will usually correct any issues.

Len,

I was dreaming about making something like this...wondering why they didnt exist...

Of course they do. How do I get my hands on them!?

Thank God I saw this as Im literally finishing up a project on the Cayenne and was about to dig into the 911. I'll get these for extra security :) and them have at it.

If the sales gig doesn't work out, perhaps metal work? That looks nice and smooth:D

And I found out that fancy little copper gasket is called a Voi-Shan Seal. Now I just need to figure the angle on the flange and size and off to the races.

Until then, I drive...with a leak:cool:

:)

The angle is 60 deg, but its soft copper so any angle will conform once sandwiched in between. The size is what matters more. I think the one I bought was AN-16.

Have not found my info on it yet, but Google is our friend. Post it when you get it.

Can't be hard to make one.
Cut it out a ring from a flat piece of copper plate and anneal it. It should form it self to the right shape.

SauCy,
I don't know whether you have solved your press fit/ sealing issue. BAT-Inc sells repair oil line seals. Here is the link

Hope this helps someone.
Cheers......

^^AWESOMENESS^^

Thank You

Ive been enjoying the car with the leak, too many nice end of season days to tear into it now. I'll do this and Carrera Cooler when I put it away for the winter.

Turns out Voi-shan, what Len had pictured above are very difficult to get ahold of as they've been discontinued or sued or some nonsense I found on the internet...probably all true ;)

I don't think those rings will work. Metric hose fittings are 30 degree "globeseal" spherical fittings vs. the AN fittings are 37 degree straight taper?

Earl's makes those AN sealing rings too if you want to give them a try.

Can get pretty much anything Earl's from Summit Racing or ANPlumbing.com. ANPlumbing is the original Earl's Store #1. That's how they answer the phone when you call....... :D

Thank you guys.

I'll do my Hw and make a purchase over the weekend.

KTL, that even better-no mods and no re-forming of the angle. Thanks for the find.

I have a couple of left over dented hard cross-over oil lines which have the same 30 mm nut and flange seat (correct description??) as the hard lines attached to the T-stat. I also have had to use the dremmel cut off the fused nuts from the T-stat. So I am wondering if anybody has successfully replaced the nut by removing and re-installing the flange seat. If so, how was it done?

:)

The thermostat seat is a 60 deg angle and the AN seal ring must deform enough to make the repair. Or a 60 deg cutter could be used if one could be found.

I have removed all fittings from hardlines, they are soldered and you need a lot of heat.
But you cant remove anything from the thermostat, it's one piece of aluminum.

This is what my thermostat looked like.

It didn't leak, but I wasn't confident that would hold again... So I got one of these thermostat saver and welded it on.

Safe, were you able to re-use the old flanges and if so what preparation and solder material did you use? Please assume that I do not know anything about soldering except simple home plumbing.

Yes, I did. Cleaned them up with a Dremel to remove old solder and make them fit the new pipe.
I don't know what type of solder I used it was something I had at home, probably some generic brass solder. But it worked!
A lot of heat is needed, cherry red.

You'ld think that a machine shop with a valve seat grinder could resurface that.

Update :)
 

After a Loonngg cold winter of welcoming/caring for my now almost 5 month old son...

I've been able to manage some time to dive back in. Last night I pulled the hard oil lines from the car and easily unscrewed them from the t-stat on the bench.

Leak source?http://forums.pelicanparts.com/uploa...1400075516.jpg

I've carefully gone over the ends of the oil lines to ensure there was no damage or marring before I get everything cleaned up and put back together.

One strange thing I did notice was that inside the female ends of the t-stat housing, the beveled/angles piece was on an angle...almost like it was tightened crooked.

I'll provide pics to compare tonight.

Is it a good idea to add some anti-seize to the threads prior to re-installation?
