Can you elaborate?

By the way, on my coast-to-coast road trip today I passed 80,000 miles on the swap. No sign of a problem with the hoses, fittings or design.

You can disconnect the soft rubber line from the hard line. It's an easier job to R&R but also *could* get disconnected due to vibration or inferior/worn out materials. On the OEM job, you can only disconnect from the oil cooler or oil filter housing. From watching these forums and talking to MB-Diesel people, in practice the only line that could totally disconnect is the one on the oil cooler, usually the lower one.

That's good, because I think the next time I need to do this (hopefully on another vehicle), I doubt I will be able to buy an "expensive" line at all and I won't use one of the inferior brands.

While I can understand why you would be concerned if you bought the items in question from Vatozone, I believe you would have less reason if you bought those items from a highly rated retailer, on eBay or otherwise. The fact that they are probably made in China is not a concern, your quality - check is through their satisfaction rating. . The Chinese are fully capable of making good products, they just have to have the incentive, which is worse why the satisfaction rating is so important.

The after-market AC hoses on my 65 Newport has those and haven't leaked in 50 years.

I used Oetiker Camps on the Hose ends that attach to the Oil Cooler itself and Norma Worm Gear Hose Clamps on the lower Hose Connections.

I used the Hose Clamps on the Lower end of the Hose because I did not have the special Oetiker Clamp (I used a Nail Cutter/Nipper) Pliers that will crimp the Clamps with the Pliers parallel to the Hose.

Of you remove the Lower Hose Metal Tubes from the Oil Filter you can do the whole job wit Oetiker Clamps (make sure the Hoses are indexed properly) and the Nail Cutter/Nipper but it is more work to remove that.

There is also more then one company that makes Oetiker Clamp Pliers that will crimp parallel to the hose.

On mods using welding or brazing; they are only as good as the person's skill that is doing the job.

However, in this case I doubt if the weight of the Hose vabrating is sufficient to loosen up even a less then excellent job.

I think a main part is if you use Factory Made Hoses or doing a Mod is everytime the Hood is open to take a close look at the Oil Cooler Lines for issues. If you see an issue fix it or avoid driving till you fix it.

The Chinese are capable of producing high-quality products. The problem is that as a nation they have shown themselves to be untrustworthy. In America, there would be lawsuits for people who misrepresented their products which caused catastrophic failures. In China, it is business as usual. American and European firms stamp their name all over their product because they want to develop a positive reputation. Chinese companies don't display their name and make it hard to find so you can't blame them or find them again. I'm not going to take a chance like that on such an important part. For a window switch or interior gadget, maybe. But, not on something that could destroy the engine.

I picked up my new oil line from the post-office yesterday. I am hoping to have time this weekend or perhaps Memorial Day to put the new line in.
I'm kinda depending on a buddy of mine to help me out. Doing this job alone is terrible, I'd like an extra set of hands and my wife refuses to drive this car, let alone help me fish in the new line...

I'm hoping to post a successful update in a few days. I think I'll go and try to loosen up the lines already tonight. I'm hoping they haven't gotten too stuck in the month that they have been on.

Question: Should I drive the car for a while and get the lines hot? Would that make it easier to unbolt them? Please say Yes. I need an excuse to drive the Benz again!

Diesel911 · #38 05-20-2015, 09:21 PM

If you have previously removed the Line there should be no issues removing it.
If someone has not mentioned it some never-seize type compound on the Oil Cooler Threads should keep it from corroding to the Hose Nut.

If you don't want to make a special trip for the never-sieze smear Wheel Bearing Grease on the Threads as that is better then nothing.

dkr · #39 05-20-2015, 09:35 PM

I agree. The issues you experienced before are because of the thing being old and in your crazy weather environment for 30+ years. It should come off very easily this time.

But, old diesel Benzes love to be driven.

@Diesel911
Thanks! I have some high-temperature grease I might use on it then!

@dkr
Say no more! *grabs Betsie's key and runs out the door for a full-throttle run down the block*.

"Sorry officer, but this guy - I believe his name is "duhkuhr" - said that these cars love to be driven, which is most certainly what I was attempting to do".

Ceristimo · #41 05-23-2015, 09:17 PM

Unfortunately I won't have time to get to this job this weekend. I put in in my calendar for next weekend, so it will get done then.

I guess the Benz will just have to sit unused for yet another week.

Quick question: I changed the oil and filter last time I did these oil lines (about 2 months ago). I have driven the car for maybe 50 miles since then. I would assume I don't have to do another oil change when I take the lower line out, right? There's not a big chance of any impurities getting into it, so I'd guess I can just top the oil back off after the line has been replaced? Thoughts?

No problem whatsoever. Whatever is in the cooler gets filtered, so unless it's water or some other detrimental liquid you're fine. You might not even need to top it off. There's not that much that will leak out.

A side note, when I drilled and tapped my cooler for the AN fittings I used, I rinsed things out but wasn't at all concerned about any residual metal filings being in there as they would be carried along and caught by the filter.

@Mach4
Thanks for the confirmation. I kinda already thought that it wouldn't be a problem, but figured a second opinion wouldn't hurt. Thanks!

In other completely unrelated news while I'm waiting for this weekend to arrive to get that damn oil line taken care off:

I noticed two little red clips on the rear bench seat yesterday as I looked the car over, and realized quickly that those are the bench release buttons. So, just for laughs I took the seat out and....well, I am now also the proud owner of a handful of pennies, a pristine looking Zippo lighter, a collection of "Pokemon" cards, and an assortment of pens and colored crayons and a used paint stirrer.....Seems at some point in time the rear seat has been home to a bunch of kids, a smoker and a paint sniffer!

Man, I wish I would know what kind of previous owners this car has had. What has happened to it in between when it was bought shiny and new in October '83, and when I got it in its current sorry state in 2015? She's rolled almost 280k miles of asphalt under her tires, but who was she carrying when doing it?

If only Betsie could talk, I'd love to hear her stories! How many people have called her 'mine' in the span of 31 years? I'd love to find out more, but have no idea how. It intrigues me...
Someone at some point in time touched up all the little paint chips, so someone must've liked this car. There's a dent in the roof that seems to have come from a crossing gate or something maybe landing on the car? I'm curious to the story behind that. Someone at some point thought that gluing back the warped wood was a great idea, but did it with the finesse and motor skilss of a 2-year old toddler, so it looks godawful.
And who broke the dashboard?

She has so many scars that I am wondering what kind of people have owner her. She must've have had loving owners at some point, but also definitely one previous owner who didnt' give a rats-ass and neglected everything. I know it's "just" a car, but there's so much history to these old ones that they almost seem to come alive!

All right, my buddy came over tonight and we got the new oil line changed out. Took about 2.5 hours all total.

At the end I had a little bit of a fright. Total oil lost was about a quart and half (I also loosened up the upper line to make things easier) so when I started the engine it was way too low on oil. I noticed the oil pressure coming up way slow, so I immediately turned it off, but it kept running since we had knocked a vacuum line loose.
I ran out and hit the emergency stop, topped the oil off, hooked the vacuum lines back up and everything seems to be running fine!

Let's see if the new line will hold.

Oh, wanna know something really cool? My door locks started working! They have never worked. And they work. Like, all of them. Including the trunk and the gas cap. How sweet's that!?
