Full Version: Is this an OEM oil line

I’m having trouble mounting my new heat exchanger on the passenger side because the oil line that comes out of the case is in the way. Ben said I should be using a stock line. Anybody have a photo I can compare this with?

Attached below is stock lines. You have pms conversion oil line. I think with some tweaking you can make that work .. Also note that if its just small interference areas then you could relieve the area as a last resort to replacing the line..

Looks like after the radius coming out of the engine it should be straight. Is that right?
mb911
Yes.. My supply of these should be ready soon and I could ship you one to try

Most guys are using stainless braided lines. Mark Epstein has a really clean setup with good pictures.

That loooks like my oil line from PMS. PMS takes a stock 911 return line, cuts off the end and welds on an an-12 fitting. Mine also rubbed on Bens heat exchanger. I had to take off the clamp, loosen the nut and push the line against the case. Everything was tight but still fit and I was able to put on the heat exchanger with no leaks. I will replace this line with a steel braided line this summer.

It looks like you have the same Patrick Motorsports line I do. The shorter one is a modified stock line. You can see there are some differences to the diameter, lenght and shape.
Steve
Yes, the 914-6 return line is smaller than the later return line. PMS modifys the later return line with an AN-12 fitting. The PMS line worked fine with the stock heat exchangers, but since Bens are boxed they rub on the line. Ben, can you make one like PMS that has a different bend or smaller pipe? I would buy one versus having to make a steel braided line.
Oh... and the fitting on the engine is different from a 2.0 six versus a later 911 engine
mb911
I will try to answer everyones questions here.

1st steve good insight for Billy and how you worked around the differences between heat exchangers.

Regarding the stock lines. I had the factory lines remade in larger diameter (same size as the GT lines) with all the correct factory bends etc so this will be a now easy solution to the smaller stock line. It would be correct size for the late 2.4s and up..

I tried to make my pms conversion hard line work with the heat exchangers. I didn’t. It worked fine with headers but no room with the he’s. I made stainless steel lines and it fit easily. I bought a kool tool to make the lines and it went from a pita to very easy.
Ben’s hardline is very nice but I was routing the line from the engine up the passenger long so using the steel line with an a/n fitting worked best for me.

Marks correct saying using a hose as being a good solution,if the OP isn't going this way you could buy the full length pipe from Pelican for about 30 odd dollars and bend it to clear,this pipe is plated copper and very soft,cut it down and refit the end to suit the hose length to the tank.
I used this pipe and bend it so it lined up with my bracket on the case and was tucked up as high as possible out of harms way.

Also I'am sure Ben could assist with some better solution.

No Ben I'am sorry now think it was around $70 ,got it from Pelican for that price or there abouts,that was a while back and see they now list same OEM part for $104,it came from a 75 911S,I had cut the curved end off and sweated the fitting back so it went straight to my tank.

Yes, the 911 hardlines are pretty cheap used. I have one that I was going to send to Ben to turn into a pms replica.

Don’t mean to pile onto a thread of good info, but if anyone needs an OEM /6 hardline or a 911 line from a 2.7 (‘74-77) to use in making your own custom hardline, just PM me.

I won’t be using either, as I will either go rear cooler or passenger side touting on my conversion.

Billy I dont have the correct -6 lines in stock just yet..

I found a local guy who can make one up for me if I can get him the specs. What ID line do I need for the return?

Stock ID is 5/8" and that is limited also buy the oil tank plumbing which is also 5/8" id.
Steve
Is that the same as AN12? My return line gets converted to AN12 then to a Mocal thermostat and then to the tank and front oil cooler., which is also all AN12.

-12 i believe is =3/4"

914forme
Line Size = AN Size
3/16" = -3 AN
1/4" = -4 AN
3/8" = -6 AN
1/2" = -8 AN
5/8" = -10 AN
3/4" = -12 AN
1" = -16 AN
1-1/4" = -20 AN
1-1/2" = -24 AN
