So, im having an unusual issue. I keep finding some sort mist on all of my turbo piping. Including the inlet, discharge and charge pipe. The mist seems like its only appearing close to where the pipe meets another section which is odd. Any thoughts of what this could be. Im finding this after I leave the car for the night and open the hood in the morning.

 

A picture would help. What color is this mist?

 

Is the mist watery or oily? Is it just condensation forming? Is it there right after you shut off the car or does it form overnight?

 

The picture is on its way.

It happens after the car is left over night. It's definitely sludgy and kind of yellowish, when I wipe it with a paper towel it's mostly black. It started with just the turbo outlet and and has now spread. So I have no clue where it's coming from.

I'm pretty sure it's not condensation because it isn't the whole pipe. It's happens within a inch of where the pipe connects.

Ironically I am leaking coolant somewhere as well as oil, or burning it up. So I assumed this is a side effect of it, but it seems very spread out. So I don't know where to start.

Does anyone else have a sludgy mist on there nm pipes after a night?

 

Are the pipes new? Are they painted? Is the finish breaking down or is the pipe metal and oxidizing? Condensation will typically form if it is cool and the air is warmer than the item it condenses on. I don't expect that to be the case nor are they exposed upward facing surfaces for moisture to settle on. Does it bead up or stay'wet' like an oil?

 

I'll take pictures showing everything tomorrow. They are neither painted nor oxidizing.

They are relatively new. Sorry i forgot to mention it's only on the silicone part. But it also sticks to the underside of the pipe. It leads me to believe its oil as when I wipe it it's almost pure black. I have a lot of blow by oil which may be in the inter cooler but I doubt that as I don't have any air leaks


Best way I can describe it. It is like the oil reside found from a leaky valve.

 

Can you put the stock pipe back on? At least one of them?

Are the hose clamps are tight? With the cold weather maybe the metal contracts more which creates leaks around the connections.

 

That could possibly explain the inlet intake and outlet but how would that explain the air discharge charge pipe. But not the air charge. As the mist is on the opposite side. The mist starts at where the plastic hard pipe begins to right before the silicone elbow. The silicone also has been stretched over it, so where you see the clamp is the end of the plastic tubing.

I've attached a few pictures the, discharge pipe has a little bit of the mist on it toward the turbo outlet, but the other doesn't ill get better pics tomorrow.

 

I see that you're running a OCC, is there a leak? I'm thinking that oil vapor is venting to the engine bay and plating out at those locations (for whatever reason - doesn't really make sense though).

When your driving air flow is preventing this but after you park that's not the case.

It's a stretch but that's all I got. Interested in the outcome though.

 

Lol I do appreciate that even if it's a stretch I'm out of ideas.
My original thought was that's its coolant leaking at expansion temperatures and with the car off it was evaporating. But mist on the other pipe no idea.

 

Lay a towel (or something) over the areas and see if the mist forms over or under the towel.

 

I'm gonna try that tonight. In the mean time here are the pictures of an early morning.

 

Looks like normal road dirt to me. Not a lot of it either. No idea why you are seeing it more there other than you just put a new accessory on your toy and your eyes are landing there first. I notice there is some corrosion on the metal in your second pic. By chance are you driving on salted roads? Not sure where you live, but it is snow season and slush holds a lot of dirty yucks. I'd call NM, maybe there is a break in period for their materials, but that would be weird.

 

That could make scenes the discharge is newer, last couple months, but if it's road dirt why would it only be popping up when the cars sitting

My thought exactly....
Sand, cinder and the newer liquid deicers such as mag-chloride(which is mixed with a thickener to make it more viscous) might be attracted to Any item that could have a slight static charge.....

 

Interesting.

I've got a cooper D (diesel engine) with a Garrett (not a Borg-Warner) turbo in it. I'm seeing something very similar to this in very similar places (although the turbo geometry and engine setup are slightly different than the MCS). It's not road dirt as I'm only getting this on and around the turbo. In your post above with 4 photos attached, it's exactly like the 2nd photo showing the blue piping and the metal pipe. The car is completely stock setup.

Initially I thought it was coming from the vacuum pot attached to the turbo actuator arm. Can't say it happens overnight, but certainly looks like a splash/mist pattern that appears. I'll try laying out the paper towel, but mine seems more dried out, likely from the heat of the turbo.

For the record, I don't have an OCC attached to the car and there are no boost leaks, so I have no clue as to where this could possibly be coming from. It's been a mystery and has been occuring for about the past 3 years.

 

I have no clue either, as to what it is

 

I took a couple photos of what looks like spray on my turbo. It's mostly on and around the vacuum pot and the oil feed pipe. Bizarre. Can't see where it's coming from.
