What can replace this oil line?

[BeauBlues]

Well I found another oil leak. This time it is a bad line. It is one of the lines that connect from the the engine to the thermostat in the right rear fender. Here is a small picture of it off the performance catalog. It's the hose under the "J" listing. http://************************/ProductPage.aspx?ProductName=Oil+Lines&productid=109940&producttype=20

I was thinking I could buy some steel braided hose to replace the whole thing. But what size are the fittings?

What I did was use braided steel to replace the rubber sections of the lines, and I re-used the original fittings and solid sections. A local hydraulic shop charged me $20 to swage on the fittings. I don't recall the size of the line, maybe AN-12

If you go the rebuild route, the braided lines are probably the AN12 size. The fittings on the end of the hose need to be the AN12 to 30mm (metric) pieces. If our host doesn't carry the braided hose and adapter fittings you can get them from batinc.net. The "crimps" for the end that connects to the steel tubing should be available from a local auto parts or tractor shop. Hope this helps.

AN-16 hose is a slip-fit onto the fittings of all post-1971 engines ... after you cut off the crimp rings! AN-12 hose is not!

For stuff like that I go to an industrial hydraulic shop. They can usually reuse your fittings (they have a bazillion different types of hose) and swage it together. Often less than $20 while you wait.

If you have a mangled fitting, there is a high likelyhood they can find something in stock that might work or steer you a shop that stocks that weirdo fitting.

Maybe it was AN-16. It's been more than 45 minutes, so it's anyone's guess

When you guys say hydraulic shop. I'm not quite sure where to find one. What should I look around for, ie: services, something like that?

beau-

in NJ, these hydraulic hose shops make up hoses for snow plows (probably never see one of those in downey, eh?), construction equipment, dump trucks, etc.. go to the section of town where you wouldn't want to be caught dead at night, ask around, you will find one. but don't expect large metric fittings to be easy to find.

also, pegasus racing in wisconsin has a GREAT assortment of fittings, hoses, etc. for your future hosing escapades.

[fred cook]

Early S Man is probably right. The AN12 hose is 5/8" inside diameter. The steel sections of the oil lines is larger than that. However, the same process still applies, just use the appropiately sized fitting on the thermostat end (ie if you use an AN16 hose then use the AN16 - 30mm fitting). The black and copper colored fittings are AN - metric adapters to allow connection to the stock Porsche oil lines.





Good luck with your project!

In my town, you look in the yellow pages under "Hoses Couplings and Fittings". Many are open on Saturday.

Beau,

That is the exact same line I had replaced a few months ago that I mentioned to you. The whole line is one part # and I think it cost somewhere around $150 for the part if you decide to go this route. My mech replaced in about 2 hours, most of the time was waiting for the part.
