landroversforever Posted September 27, 2017 Share Posted September 27, 2017 Does anyone on here know of a brand/type of hose that would be happy living in the sump of an engine? I'm looking for a 16mm ID hose that is capable of living in the oil and temperature of an engine's sump. I've been told by the merc lot that the pipe is another pickup tube, but it doesn't make sense as you'll see in the picture below, it's nowhere near the oil level at its end! So it's potentially a suction tube. It's the tube that starts too left and ends by the silver band on the lower tube. So it ends long before the pickup tube drops down to the sump. Thanks in advance!

muddy Posted September 27, 2017 Share Posted September 27, 2017 Hydraulic hose? Quote Link to comment Share on other sites More sharing options...
Cynic-al Posted September 28, 2017 Share Posted September 28, 2017 (edited) Hydraulic hose does adsorb the oil over time and go sort of porous and flaky but if it's not under pressure and you have a filter I'm sure it'd be fine for many years? Our hydraulic machines keep the oil at 50 degrees but I'm not sure what the max rating is without looking it up. If it's suction does the hose need to be rigid to avoid collapse or do you think that wouldn't be a problem? Is there not a Mercedes part that does this? Or could you not weld a bit of "steel" pipe on as won't a rubber hose flop about as your offroading and maybe come out the oil or hit moving parts? Or am I misunderstanding?

landroversforever Posted September 28, 2017 Author Share Posted September 28, 2017 IF its a suction hose I can't see there being much suck on it really. Well there is a mercedes part, but its the original tube on the pump and its in the way of my sump notch! so Yes, but no Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted September 28, 2017 Share Posted September 28, 2017 Hoses that carry a fluid are almost never happy being submerged in it, same with sealants, ask me how I know! You're into quite special stuff there, best bet is to get on the blower to a hose manufacturer's technical line to see what they say.

Bowie69 Posted September 28, 2017 Share Posted September 28, 2017 Hmm, as you say, it doesn't look like a pick up, either a breather, foam scavenge or pressure relief port maybe? All seem a bit odd, but then I don't know much about OM606s! I'd try and confirm what it is before deciding what you need to do.... workshop manual show you anything?

muddy Posted September 29, 2017 Share Posted September 29, 2017 What about some flexi steel pipe like an ibaspakker exhaust? Quote Link to comment Share on other sites More sharing options...
zardos Posted September 29, 2017 Share Posted September 29, 2017 I found http://www.hoseworld.com/ very helpful when I wanted some more specialist hose, give them a call. Quote Link to comment Share on other sites More sharing options...
Daan Posted September 30, 2017 Share Posted September 30, 2017 why do you need it flexible? Quote Link to comment Share on other sites More sharing options...

I can only imagine how you found out Once you look into hose construction and the various layers used then it makes sense. Quote Link to comment Share on other sites More sharing options...
HoSS Posted October 5, 2017 Share Posted October 5, 2017 I had thought the second tube was bypass i.e. where the oil is dumped from the pressure regulator. Quote Link to comment Share on other sites More sharing options...

Well that's what I'd have guessed.... it really doesn't make sense for it to be a pickup given its location. I've ordered some tube that should be here tomorrow and I've borrowed a bender so I will see what I can come up with for the tube. Quote Link to comment Share on other sites More sharing options...

If this is the case there's a fair chance you could just cut the pipe wherever is convenient, unless Mercedes have some weird weakness that requires extra oiling of whatever's near the end of that tube. Can you not find out from the service manual or somewhere what it's actually for? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 5, 2017 Share Posted October 5, 2017 As above I strongly suspect it is a pressure relief return, dumping it into the deepest part of the sump, right above the pickup, so it doesn't have to drain down the pan at all.
