Hi guys, I need help, once again.


First off, since I installed my exhaust, the car spits this crap out of the pipes during cold sturtup. Some water builds in the tips and little crappy drops come out of them . After a minute or so, with the exh. warmed, condensation goes away as well as the black drops.

Why is this happening?

Second problem, my driver's side boost hose seem to be loose, but the metal clip is fine.....
I will upgrade the hoses in a couple weeks, but could this be a Y-pipe connection fault?
I also noticed some oil sitting in the hose, not a lot, but still there. Is this caused by the turbos??

Thank you in advance, as always!!

 

I have never seen that black before - is it oil liquid or oily solid or dirt/non-oily solid?

Looks like the ear on your boost hose is not holding tight. May be able to pop it off and see if the ear on that side of the hose has been pushed in or something - the ears are on the silver part of the hose.

 

The oil in the pipes just after the turbo is normal. As long you don't have a pool of oil in the pipes. Good info here:http://www.renntech.org/forums/index...e-need-advice/
The drops on the floor can be related to your outside temperature and humidity. After you stop the car , in certain condition especially in high humidity, you can have a build up of condensation inside the exhaust and as soon you start the car it spit out. As long this is not oily and your coolant level stay normal you should be OK .

 

I would not worry about any of the above!

 

That's condensation (water) that is coming out the exhaust. Are you running cats? it's more pronounced if you do not have cats. The black stuff is just built up carbon in the muffler that the water is spitting out. This is normal for cars. I've seen cars start up and pull away leaving a stream of water coming out the tail pipes. Do you go for short rides and park or let the car sit. Water is a byproduct of combustion. Might also be running a bit rich with aftermarket exhaust.

 

Thanks a lot guys!!

Thank you Mike!Good to have some moral support!


Well, my coolant level has been stable for the last 6k miles.

The drops are not oily at all, if I put my hand in front of the exhaust and get some drops on it, the "liquid" dries off quickly and the only residue is that black stuff.


That stuff on the garage floor is dry, and seems to be combustion residue.


I must note that on cold sturtup the amount of water that forms into the tips is huge, it litterally drips out from the tips..
It could be a combination of cold weather (cold exhaust) and very bad pump gas with lots of water in it...right?

 

This is what I thought too...

I'm on 200cpsi high flow cats, that will go away when I install my new turbos.

Basically I take the car out for a 20-30 miles spin once every week.

I thought about it being a bit rich too...

The funny thing is that left side is a bit more clean, so it could also be that one of the two lambda sensors is on its way...am I wrong?

 

This is a typical symptom of excessive combustion bi products collecting in the exhaust system. Could be due to a few factors. Condensation is normal but expelling black onto the pavement is not. I'd also check turbo to intake hoses for excessive oil residue.

 

All normal... go worry about something else...

 

Italian tune up time! Blow all that gunk out!

 

May be Berlusconi mistress Ruby.....

 

J-P: I think that you have been inside too long in the Canadian winter.

Emadelta: The normal byproducts of combustion are CO, CO2 and water. When your exhaust is hot, the water is converted to vapor and you never see it. When it is cold, some of the water condenses on the cold pipe, and it collects some of the black combustion residue (soot) that coats the inside of the exhaust. That is where the black stuff is coming from. It is mostly normal.

Perhaps when you installed the exhaust, the tips were tilted up slightly, which would allow water to collect in them more easily. You might be able to point them down more, and that would reduce the pooling and washing out of the soot.

Good point Jon, I will try..thank you!


As for you two JP and Alex...well...I wish I was invited to the parties!!!
Seriously....IMO italian prosecutors go after him even if he farts too much lately.
