Bottom oil line on 914/6 oil tank.... Options

[Joe Bob]

Stoopid freaking rotten godamned oil line is sweating out the pores of the rubber and cloth weave oil ine.....looks like a replacement is needed.....I don't think it can be removed without pulling the tank.

Anyone been able to get up to that nut with the tank in place? Should be the 36mm one ........ (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)

Yeah, it can be done, but you need the special wrench.

[Joe Bob]

OK....anyone got one?????

All I have is one of those thin bicycle 32/36mm double open ended ones....

[Porsche Rescue]

Mine's leaking too. I was thinking the fitting was loose. Same question, where do you get the magic wrench?

[Rusty]

I hate to say this... check SkyRat.

I took it off with a crow foot and long extensions. I dont recall the size. I didn't have a metric one so I substituted a close sae.

Z, I called my crew chief Steve Aven. He has the tool. The brand is Stahlwille. It can be purchased from Baum Tools. Bring your 914 to Orange, California and we will take it off for you for free, if the oil has been removed from the car in advance of your visit.

Can you give a more detailed description of the tool? Just looked at Baum's online listing of 78 Stahlwille tools and don't see anything that looks like it would do the job.
Will Baum know what I want if I ask for a wrench to remove lower hose from a 914-6 oil tank?

Sorry, I'm the driver and Steve Aven is the wrench. I will call him tomorrow and then post the nature of the tool.

from Stahlwille "programme 2002":

crow ring spanner
36mm
1/2 "dr
code:03190036

note this is tool I used to do it. When others say "special tool" as if there is a "lower 914-6 oil line remover" - well, good luck. Also, the code # is for the 36mm. They also make them in 30, 32, 41, and 46mm

Pulled the tank replaced the line and fixed the tach.......woo hoo...I'm ready for the track.... (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)

And just where does one purchase such a tool?

please confirm size - 36mm sounds about right, but this was 10 years ago and I no longer have it. BTW, "Z" took the tank out - I've had to do that too and its a miserable job.

For a fix of a related problem …

The oil line on the bottom of the 914-6 tank uses aluminum fittings (read: fragile) on a very rare hose. The design relies on the aluminum squeezing the hose between the inner and outer portions of the fitting to secure the seal.

Over time they begin to leak. Why? Because the heat cycles eventually harden and shrink the rubber. When it shrinks there’s more gap between the inner and outer parts of the fitting and oil escapes.

Unless you scavenge one from a 6 or an early 911, a replacement hose is very tough to find. The following is a simple repair my brother worked out on his 911S that has also worked on my 6.

Remove the rocker panel. Separate the fitting at the union where you typically drain the oil. If the hose at the tank end is loose on the aluminum fitting connected to the tank, it will unscrew pretty easily by twisting the hose. Of course, this presumes that the aluminum fitting is tight where it mounts to the tank. If it isn’t then you need the crows foot wrench or take the Z approach by doing a tankectomy.

Once the hose is separated from the aluminum fittings, rinse with solvent then clean thoroughly with acetone to remove all traces of oil from the rubber hose ends. Likewise, clean the fitting ends with solvent and acetone. Carefully coat the hose ends with a thin film of silicone sealer (Permatex or equivalent) and reassemble snugly. Silicone won’t bond to anything oily so be sure to get it clean. Let it set for 24 hours or so before putting oil back in the tank.

I know Cap’n Krusty is going to gag with the use of silicone sealer but there aren’t many other choices with this one. BE CAREFUL not to apply excess sealer but this fix is cheap and it works.

I had difficulty getting the tank end of the hose installed and had to bend the hose in half and keep it that way with a tie-wrap in order to thread it back onto the tank fitting. That hose is stiff. I also had to start threading the outer fitting onto the inner one BEFORE screwing the hose in because the hose was so stiff that it would cause the outer housing to cross-thread on the inner fitting.

Below are some photos of the typical swedge-style fitting that’s used on each end of the hose.

HTH,

that's it. The end.

When I built my /6 conversion I found I could readily source rubber oil lines that work with those fittings by going to the local hydraulic stuff supply store. I have found that even a fairly large one will be happy to help.
