The shop accidentally tossed my oil-feed line = upgrade opportunity? :p

Wondering If I have any options, other then stock...


Found the following example which is NOT om617 specific:

The originals have been known to crack. Not sure if a stainless braided hose is better or not. I'm guessing not.

What line would that be? the little black line to the Injection pump?

Be careful now, messing with oil supply lines, you will get flamed.

I guess from the picture you are speaking of the Oil Supply Tubing to the Turbocharger.

Since the original tubing is reliable and works a replacement would not be an upgrade just a replacement.
I do not know of any braided Hose that will last 25+years.

If you are speaking of the Oil Supply Line/Plastic Tubing with Banjos from the Block to the Fuel Injection Pump I have an extra new one I will sell for $13+ shipping (need zip code to check the amount for shipping).

turbo...sorry

starting to sound like a trip to the yard is in order...

I had a shop build me a custom braided stainless steel hose, but I wouldn't recommend this direction. The hose fell in an odd place in its routing which I didn't like and I ended up shrouding the whole thing in a length of fuel line so it wouldn't rub on anything metal. It works fine but it's hokey looking. It was also $80. I should have just had them repair the leak in the OE line.

shop picked one up from the yard, and brazed an end on it:




nothing fancy, but should work nicely.

Nice install did you do it or where was it done. More pics

If they got one from the Junk Yard why didn't they replace the whole tubing. I am thinking it can from a non-Mercedes.

I think you should have held them to getting the correct Tubing since they lost the original.

original line would not have worked, because I'm no longer running the original oil-filter housing.




btw, he found the line after the new one was in place...isn't that how it always works :p

"isn't that how it always works" It sure works that way for me too. (Today: I have at least 8 Metal Stakes used for holding the wooden forms when you do small Concrete jobs. Today I need 4 of them and could find none. Had to buy 4 more. Since they ought to last longer than me I guess I have to consider them an investment.)

I misunderstood I thought that you wanted the Stock Tube to use as a s
as a Stock Tube.

Part of the reason I did not occur to me they would cut it as they did because you can buy the Oil Inlet Flanges from Gasser Speed Shops.

Or they could have made one from Steel Plate and tapped it with a Pipe Tap so you could use any fitting you wanted on it.

nice link...thank you sir

found the following from another journal-bearing turbo manufacturer, and was wondering if anyone had any oil-feed pressure data associated with our stock turbos?

thanks,
manny


Holset permits oil return pipes to decline at an overall angle of not less than 30 degrees below horizontal. All turbocharger applications require a pipe of internal diameter greater than 19 mm which has integrated connectors. To ensure oil returns into the engine under all operating conditions, the return connection into the engine sump must not be submerged and the outlet flange of the turbocharger must be 50 mm above the maximum oil level of the engine sump pan. Crankcase pressure should be limited ideally to 0.8 kPa (0.12 lbf/in2) but 1.4 kPa (0.20 lbf/in2) can be accepted by reference to Holset.

Oil pressure of 150 kPa (20 lbf/in2) must show at the oil inlet within 3 - 4 seconds of engine firing to prevent damage to turbocharger bearing system. A flexible supply pipe is recommended.

The minimum oil pressure when the engine is on load must be 210 kPa (30 lbf/in2). Maximum permissible operating pressure is 500 kPa (72 lbf/in2) although 600 kPa (88 lbf/in2) is permitted during cold start up. Under idling conditions pressure should not fall below 70 kPa (10 lbf/in2).

Recommended oil flows for the turbochargers are 2 litre/min at idle and 3 litre/min above maximumtorque speed.

It is hard to say because of differences in Turbochargers.

The Oil on all of the Stock ones I have seen on Trucks and on the Mercedes drains out of the Turbocharger by Gravity.

On Trucks I have seen where the Driver overfilled the Crankcase with Oil and the Oil level restricted the Turbos ability to drain. This resulted in Oil leaking into the Compressor Housing (the trapped Oil had to go somewhere).

I read somewhere that on Turbocharged Race Cars they have an Oil Pump that sucks the drain Oil out so that too much Oil does not get trapped up there.

As far as Oil supply goes not all Turbochargers use the same type of Bearings.
The Bearings in the Mercedes Trubos are 2 Free Floating Bearings. The Bearings in some Turbos are single semifloating Bearings. So the Oil needs could be different.

In the Manual they give a maximum pressure and volume of Oil that a New Oil Pump can put.
Perhaps one of the Engineering Members can figure out what the Oil Flow to the Turbo is at X amount of Pressure through the X sized ID Tubing to the Turbo.
On my own Engine my Max Oil Pressure is 97psi when I hooked up a test Gauge and the Engine was revved when Hot.
