Blue Smoke On Startup

[peterk9]

I have a 2023 Lincoln Aviator that has just started the blue smoke on cold start but not every time. Has anyone found a solution? I have it scheduled for service in a week. Reading these I’m thinking if they can’t recreate it it’s going to be a useless visit.

Just wanted to say, Welcome to the Forum.

My wife purchased a 2023 Aviator in Sept 2022 (writing now July 2023) that has these same symptoms - blue smoke on cold engine startup - more pronounced after sitting for a day or two.

SUV has 10,700 miles now - dealer oil changes at 5,000 and 10,000 miles - smoke started at ~9,500 miles.

Reported to the dealer - dealer was unable to replicate after a two day visit.

Have you found a resolution?

Thank you,

Scott

Scott I bought a aviator at the same as you did and started experiencing around the exact same time. My car was in the shop for 1.5 months and they came up with that "it is normal", I don't believe for 1 second that it is and lincoln needs to do something about this!!!

It seems that only a small number of owners have reported or noticed this and no one has apparently found the cause. There are some 6th gen Explorer ST's with the same issue. The common thread seems to be that all the vehicles have turbos. As for having Lincoln do something about it is easier said than done since I don't believe the root cause has been identified and it doesn't seem to be a widespread issue.
Neither my previous 2020 aviator nor my 2023 have this problem.

Same thing happened with my 2022 Aviator. They diagnosed as a PCV issue initually, changed it, but did not fix the issue. Have been dealing with it and Ford/Lincoln since. Now they have broken down the engine and have found water in the components of the engine. Waiting to hear from Ford/Lincoln for next steps. Mr car has been in the shop for over a month this go round.

I have a 2020 with the same problem brought it to the dealer the said they never saw smoke took it home two weeks later the next morning started it smoke comes pouring out the tailpipe and every day after I’m wondering weather they even started it at all any solutions yet?

They never saw smoke because if the car is on a level surface it doesn’t smoke it has to be parked on a un level surface preferably with the front end higher than the rear and overnight

Hello! We have a 2023 Aviator - just over 30K miles - dealer serviced with Mobil 1 every 5K miles since new. On occasion - the Aviator emits a few seconds of blue smoke and has the smell of oil. It will run you out to the garage when it happens. Oil level remains consistently full. This started about 9,500 miles and then stopped and has started again. The smoke appears worse if the Aviator sits fir a day or two and also I've noticed about 10-20 drops of water somewhere under the engine on days that the smoke appears. I've considered changing to a high-mileage variant of Mobil 1 (even though 30K is not high miles). Does anyone have any thoughts? Thank you!

My 2020 Aviator emits blue smoke on startup. Is this normal?

My 2020 Aviator emits blue smoke on initial startup of the day. No smoke afterwards. Dealer says this is normal, I opine that it is not. Whose right?

Blue Smoke On Startup

6000 miles on 2022 Aviator. Blues smoke from exhaust after sitting that goes away after a few seconds. The longer it sits the more smoke bit it usually sits for a day. Dealer is changing the oil and said they will go from there. This doesnt seem like a solution to me. I am not accepting this as...

Same issue. This is the fourth time in the shop. They did change the turbo out because I brought it in for smoke, but it continued after the repair. It’s been in the shop for four weeks now. They were finally able to replicate the smoke so they’ve seen it outside of my videos.

Was your smoke problem ever solved I was told bring it back when it gets worse

The member you quoted was last seen here on Oct. 6, 2023 so may no longer be following.

This video may be the solution here for anyone else who has this issue. Oil supply tube from the head to the turbo. Not sure if Aviators would have this same fix.

Edit: Never mind. I see this was posted in post #25.

I am experiencing the same thing with my 2021 Aviator. It started smoking at around 10k miles. Took it to Lincoln and they say they can't find anything nor "make it smoke" I have sent several videos to them but still not fixed. It is currently in the shop at Lincoln AGAIN and I refuse to pick it up until it is fixed. It will only smoke after it sits for a couple days. My husband seems to think it has something to do with the drains coming from the turbos.

I have a 2022 Lincoln Aviator Reserve with approximately 62k miles and have noticed a smoke bloom 4x times now (all within the last 3-weeks). I did check the oil level to make sure it wasn't low, but I did not check to see if it high.

The smoke seems to only happen on start-up after the car sits for a while in my driveway. My driveway is on a slight angle up and I am not sure if that plays into it? My last oil change was less than 2,000 miles ago at the Lincoln dealership. I will check the oil level now in my garage (which is level) to see if it low or high.

I am thinking this sounds like oil leaking into the intake, and that Lincoln has a limited service campaign on the 3.0L intake gaskets. Thanks, Dave R.

New models with turbos can have smoke because of issues with the turbo or combustion pressures that the turbo generates.

Older models would be a matter of checking basic things besides engine oil level and using the correct weight oil.
Clean/service the crankcase vent system
Colder ambient starting conditions in high humidity areas will create smoke from moisture condensing
Fuel injector that is squirting too much*
Valve stem seals that have hardened.
Basic engine issues that can be diagnosed with a compression test. Head gasket/head warp/cracked head or block/broken cracked piston rings

*This condition will likely generate a DT code.

TO DaveR, longer non-use of an engine allows the oil to leak down. In addition when starting on an incline with the front pointing up can mean the oil pump has less oil to work with upon start up. The oil pump is in the front of the engine and the pump pick up tube is further back. See link for vid*

Correct oil level become critical for that scenario.
If you do your own oil and filter changes, you can partially fill the oil filter before installing the new one. In a stock modular engine this is a little tricky because the entire filter cannot be filled as the filter has to be tipped some to install. I do this on my modular 5.4l engine so on next start up there is more oil in the system. (and less air) The pump pushes oil into the filter and the oil goes out the filter into the engine. By partially filling (or fully filling on vertical mounted filters) the filter, then engine gets more oil sooner.

*This vid is about oil pump priming after a rebuild of a modular engine. Aviator of that model year has a modular 4.6l engine, Just to give you an idea of pump pick location.

Thank you for the input. I have a 2022 with a 3.0L Turbo engine. Lincoln has a very small amount (87k) of engines on recall for a bad intake gasket. I agree that two things are in play: 1) the engine is cool; and 2) the incline.

Over-filled? No, I checked my oil level, and it is not low or over-filled. It appears to be right on the full-mark.

My Aviator smoke problem continues. It seems to be most noticeable when the vehicle is parked overnight and the engine is at ambient cooler temperature.
