Blue smoke out of exhaust

[LeonBorden]

So why has nobody tried running a restrictor at the turbo?

Don't all DI cars puff some smoke when you get on them? My un-modded Focus ST smokes a little on full throttle.

Those are particulate emissions mostly due to injector spray pattern, fuel rail pressure, and injection timing. It's a case-by-case thing. Some current engines don't make a whole lot of smoke. It has to do with how the engine was designed and tuned from the manufacturer.

Starting with 2017 model year the particulate emissions will be regulated for DI engines, so expect visible smoke to go away or greatly decrease.

Are we going to get some sort of exhaust filter like Diesels have? Something else we have to delete? Haha

It's more likely they will change the fuel system to raise the fuel pressure, which can make the smoke and particulates go away.

I don't know about everyone else but it's not fuel (tune) that's causing the smoke it's oil seeping by the seal hence the title of the thread "blue smoke" plus the smell is of oil burning

that's normal stormtrooper I got that even prior to removing the stock downpipe anyhow its more apparent now with the catless downpipe in the am. bumping the idle has helped with smoke at idle but one thing I noticed when sitting on an incline the smoke came back:lol: the whole restrictor and bumping the idle only mask the issue at hand they do help but the turbo is still leaking

Just thought I would share:

I saw 2 different brand new 2015 f150 ecoboosts. The one thing i noticed right away was they both had smoke at idle and when on the gas. Not alot by any means...more like the smoke you see on a very cold morning from other cars. However, it was 55 degrees.

I saw a few weeks ago a post about early f150 ecoboost having this issue.

Stormtrooper, did you smell burning oil when you filmed your smoke..?

Yeah, that is standard condensation smoke.

Orange: Just checked this thread after a week. As noted higher up, I've got the same thing going on. So, they are replacing your turbo? You've conclusively determined the turbo leaks?

Yes after checking things out myself & then touching base with the dealer they came up with the turbo on the exhaust side seeping out the seal so I'm just waiting for the warranty one to come in. Adam from MAP bumped the idle up which helped allot but just yesterday I was pulling into my brothers driveway the car was at an incline & the smoke screen came back..:frusty: but once I got it back on level ground it burned off then the smoke dissipated

Well, if that's the case, I guess I better start reverting to stock and visit the dealer.
