Got a dripping oilpipe leak and when I looked at how it is mounted I don't believe I can do it myself!?

The mounting on the radiator has good access but the one on the transmission seems impossible to get to without lowering the transmission and/or take the cat off? I'm not even sure if I get both ends off if it is possible to get the whole pipe out under the car as it has alot of bends in it? Do you need to lift the engine or subframe?
I'm hoping there is a way of cutting it off near the radiator and only replacing it at the front? Would there be access enough to shrimp on a new rubber piece?

 

Can't find anything in the workshop manual on how to get them on or off!?

 

I'm having a hard time figuring out where that is. Up by the radiator? Or at the transmission?

I also don't see a leak. Maybe its the dark picture...

Search here for a transmission fluid change thread, there are a few (with pictures) that show the removal of the tubes from the transmission. Lowering the transmission a little bit is also straightforward if you need more access.

The leak is up by the radiator where the rubber hose is attached to pipe that connects to the radiator.
I'll try to search to find how to lower the transmission so I can get to the bolt holding the pipes.
This is how the undertray looks!

It drips pretty bad, don't know how much fluid I've lost but that is a later problem.

 

The rubber hose is a pre-built low pressure hose assembly. It goes from the radiator TF section to the transmission. I can't tell if is the supply side or return side. I would replace with factory assembly. Looks like it is leaking where the hose was crimped to the tube end.

 

Yes, that's where it's dripping.
Was hoping someone has done it and can give me some advice. Can't find anything in the workshop manual on disassembling them.

 

Ah I see now. Well here is the assembly for it. Looks like you will have replace both pipes as 1 piece.

A good idea if one’s failed, the other’s likely soon after.

 

Off course the shop near me is closed for vacation another 3 weeks so no luck there with asking how and what it costs. Did a search on the internet and the oil pipes seem to be scarce and expensive, around $5-600. I did find a company in Germany that sells them for 146 Euro shipping included!? I have ordered and am waiting eagerly for what I'll get, I'm not sure I get the right part as the price difference is huge!?

Had another look under the car yesterday and by removing a heat shield that screwed to the transmission I think I can get to the bolt holding the pipes in place. Front connections shouldn't be a problem and then I hope I will be able to wiggle them out.:-)

 

That does seem like to be a very good price but hopefully the right parts
Check the transmission flush DIY sticky as the transmission ends of the pipes are disconnected in that effort. Very straightforward.
From reading this procedure, the frame clips supporting the pipes along the run heading forward can be difficult to release so check those while you are exploring.

 

Pipes are loose on both sides but it seems impossible to get them out!?
I'm seriously thinking of cutting the bad pipe off and have a shop attache a new hose. Then find a hose(silicone?) that fits right over the pipe and use
clamps to tighten it back together? Jagtoes said it's low pressure so maybe it will work? How hot is the oil going to the radiator?

Here is where I'm thinking of cutting it.


Taking the car to a shop will get very expensive I think so trying to find options........

 

“If” i were to replace the metal hosing, it would only be with an reinforced fuel/oil rated hose. I would not want the hose either compressing or expanding during its use. It goes without saying that I would also be double clamping at both ends, probably with a compression washer/ring positioned between the clamps.

That’s a big “if”, though. I’d much prefer the fabrication of metal hosing as a replacement. I’m sure the engineers factored in the heat dissipation using a metal hose as opposed to some other material.
Also, I Can’t imagine the world of hurt you’d be in if the hose ruptured during the operation of the car.

Apologies for interrupting your train of thought. But I frequently see “modifications” made with household materials as opposed to automotive or marine rated materials. It is not a safe practice.

 

I got the name of a garage that changed the pipes on a car in England and gave them a call. They did change them whole but had taken the front off the car so they could pull the pipes out that way! They still had to bend them to be able to pull them out under the car. They told me to be very carefull when bending the aluminum pipes as they can easily brake.
So I decided to cut it off!

I had a hydraulic company make up a hose all the way to the radiator. Braided the pipe slightly before sliding the hose on. Time will tell if it was a good decision.:-)
The German company I ordered new pipes from didn't have them in stock and are still looking......!:-(

 

Transmission oil lines are fairly low pressure so if you have a good seal they should last. Just check and retighten the clamp in a week or so.

 

How about just using heat exchanger tubes where possible? There are also add-on versions where you can use the existing tubes and thermally attach the fins to them.
These work quite well, but are somewhat susceptible to damage.

 

Not much room to use it anywhere between the radiator and transmission.
