Mine is the same....it drips a drop or two or three everyday! Wow!

For me, I'm not going to get excited about it, as long as the drips don't get more frequent.........

Yeah I have been down this road when I first got my car. The fittings look pretty standard, I'd pull the cooler and bring it in to the shop. You should be able to find some that work.

I however needed the car quickly and didn't have time to mess with it so I ordered new lines from Phil.

BusyBenz just remember to keep an eye on the oil pressure guage, they do blow if the crimp gives way.

im worried about this getting serious very quickly.its more like a small puddle.the metal tube is visibly oozing oil with the engine running.when it break=total oil loss.this fact alone may justify the$500 cdn replacement cost but ill try for the alternate solution first.

yep that $407.52 translate into about $500 canadian by the time you add exchange,shipping taxes.outrageous for what it is.but your caught by the short and curlies on this one.the local hydraulic dude made a power steering hose up for me for 78 450 sel under similar scenario.but the metal fittings must be good.im willing to buy a used set even with blown rubber hoses.

PRICE ALERT.

I installed new oil lines on my 115/300d for about $10 and they are as good as original. If your fittings are good DON'T buy new ones. They can be very pricey and often difficult to find.

To make the hoses first mark the way the fittings face on each hose. Twisting hydraulic hose is difficult.

First grind off the crimp collar that holds the hose to the fitting. I removed mine by cutting it off with a hand grinder. You can do the same with a bench grinder. Once the collars are off and the fittings free take the 4 fittings and the 2 hoses to a hydraulic repair shop or a parts store that makes hydraulic lines. They can usually cut new lines and recrimp the fittings while you wait. Be sure that the shop gets the fittings facing the right direction.

W124 oil cooler hose replacement as PM?

One of my thoughts that have come out of some recent forum discussions of oil pressure alarms is what the cause of an oil pressure failure might be. Certainly one possibility is the pair of metal/rubber hoses that lead from the oil filter housing to the oil cooler. Mine are not leaking or damaged and the rubber has not yet turned hard but I'm wondering if the hoses should be replaced as preventive maintenance. Hose failure would dump the engine's oil onto the road and you wouldn't have much time to catch it and shut off the engine before irreversible damage was done. At least the low point on the hoses is clear of the belly pan, so any leaks would run down and make a drip spot where I park the car.

This is not a simple decision: Phil's price at the moment is $473.22 for part number W0133-1715552 "Oil Cooler Hose" (set of two) plus (2) part number 012 997 56 48 "seal rings."

Another option would be to have a hydraulic shop put new rubber on the existing metal fittings. That puts the car down for a few days but would save a lot of money.

The third option is to continue keeping an eye out for leaks and otherwise do nothing. What have you done?

Don't mess around with the oil lines, just order the OEM replacements. If you lose an oil line you are likely to lose the engine. It's not worth playing around with aftermarket, used, or homemade lines.

Jeremy I thought that was a misprint. $473.22 . are they gold plated?

I had to look it up, Dang, you are right. then I looked up my 85 300D. $178.81 for the two.

There is nothing special about MB hoses. just two bent pipes with a rubber hose crimped on the ends.

I had mine made at a hydraulic hose shop. I used my Dremel with a cut off wheel. made a cut down both sides of the crimp, pried it off and pulled off the old hose. took the 2 bent pipes and the 2 off the oil cooler to the Hose Shop, and they welded on hydraulic fittings, and made new hoses with Parker Push Lock Hose and fittings.

These hoses had been on with the old engine, and now 22xxx miles with the new engine. I don`t feel this is a hack job in any way, the hack job is the price for new one`s.

I have had a lot of hoses made from this shop for Road Graders, Back Hoes, Dump Trucks etc.... and the hydraulic systems on these are a lot higher pressure than the MB oil system.

when I changed mine the first time, the date on the crimp was 1984. so they had been on for 20 yrs. now that is pushing it. the rubber was hard as a rock. they should be changed probably at 10 yr entervals to be on the safe side.

I`ll post a couple pictures if interested.

Well, my indy refuses to use aftermarket hoses ever since he had to buy one of his customers a replacement engine. That's enough for me to use nothing but OEM replacements for this service. As I recall they were less than $500, cheaper than a single (dealer only) AC hose I had to buy for the 240D a few years ago. Personally, it's not worth my time to have them fabricated if I can get them from the dealer with a phone call.

I agree they need to be replaced at some interval. I replaced the original hoses when I bought the 300D in 2001, and replaced the hoses and the oil cooler (both OEM) when I replaced the engine about a year ago. It's still cheap insurance.

Get those lines repaired by a competent hydraulic hose shop- they will be better than the OE replacements. I have an excavator (3 cyl Yanmar diesel!) that burst a line that was constantly flexing. The burst strength of the new hose is 3500 psi-I don't care how good your oil pump is-you won't pop those. Many of these shops have a hand held crimper for A/C lines- mine were repaired on the car. Cost 200.00 complete.

I'm not saying it won't work, but I wouldn't buy a car with fabricated lines (or I would adjust the price by $500 and fix it ASAP). Is it really worth messing around to save less than $300 and ending up with a setup that's not correct? Sorry, but I just don't get it.

I don't get it either, ... in a different way.

Mercedes hoses are crimped
Locally produced hoses are crimped

Mercedes hoses are rubber/hydraulic hoses
Locally produced hoses are rubber/hydraulic hoses

I have hydraulic hoses made locally for boats and equipment, the cost of replacing one CAT C-12 in the belly of the boat is more than my car was when new, I don't skimp on hoses or any other part.

Properly made hoses are worth the trip to a local hydraulic shop, and I trust them more than the purchasing agent at Mercedes-Benz USA.

Oh, and I've been a supplier to Mercedes-Benz as well as most of the major automakers of the world, suppliers screw up too.

The only difference is, if the Mercedes-Benz original hose fails new, you MIGHT have a claim that Mercedes will honor, ... might.
