You mean if he goes in with 3,000 miles on the car and blue smoke coming out the exhaust they won't fix it? That's never been my experience from either side of the service desk, but your experience might be different.

Establishing yourself as a pest who shows up for every little thing can work both ways. And, a little blue smoke on a new car is a little thing. It can get you better service, or can get service departments blowing you off. When that happens you need to contact Jeep customer service just to have them find a dealer that will work with you.

No...not really how I meant it. First, blue smoke on startup is never normal. Even during break-in. No service department I know of would consider anyone to be a "pest" for being concerned about that. If the OP was obsessively checking his oil and was hyper concerned about a slight USE of oil during break-in that would be a different story.

Second, manufacturers respond more aggressively when problems are documented early on. During that phase they are much more concerned about owner experience and avoiding buyback situations. It shouldn't necessarily be that way, but it is.

Re: Blue Smoke on Start Up

I've had it too, along with the smell, in the first few thousand miles, especially when starting via remote. The condition resolved itself by 3000 miles

Smell is one thing and a different phenomenon. All new vehicles will have a "burn off" smell. However, If you actually got blue smoke (not vapor) from the exhaust that's abnormal. Blue smoke --on startup-- means there is oil in the combustion chamber at the time the engine starts. From where? The rings being incompletely seated will affect oil getting past them when running during break-in...but those are minuscule amounts. You don't see blue smoke from that, and it isn't in the chamber during startup.

Re: Blue Smoke on Start Up

I wouldn't bother. I don't know of a new car that doesn't do this. It's just a matter of whether anyone notices it or not, and most people DON'T notice. Some burn more than others. My Jeep did it and so did my Dart.

I see it at work every day too, whether it's the 2.9L, 3.6L, 5.7L or 6.4L. I will say that the 5.7L and 6.4L are the biggest offenders. Every engine burns a little bit of oil when it's new. The blue smoke WILL eventually stop.

Marlon, I'm surprised. While I agree with you that all new engines burn some oil, it usually doesn't exhibit itself as a puff or chug of blue smoke on startup. I've seen new engines do it if you goose them after they've been running...but never have I seen a new engine puff blue smoke immediately --on startup-- without there being something out of sorts. (unless it's the 5.7 on a forward incline situation).

At work you might see this every day (first start ever) because of the assembly lube burn-off. That's pretty much gone after the first few seconds of the engine running and will cause blue smoke very briefly. But I don't believe any engine should have blue smoke on startup otherwise -- that indicates oil in the chambers before the engine is started. It's certainly not crawling up the bores while the engine is off.

Just my 2 cents.

When an engine is placed inside a vehicle, the first startup on the line is NOT the first time it is run. That "assembly lube burn off" is taken care of at the engine plant, before it is even shipped to us, they already have oil in them, etc. YES they are even run all the way up to WOT.

I can go up and down the engine line all day, every engine will already have carbon deposits inside the exhaust manifolds.

Re: Blue Smoke on Start Up

I have read a lot about catch cans on this forum.

If a car does not have a catch can, doesn't the oil the PCV valve picks up get sent to the intake manifold?

I have never noticed that puff of blue smoke when I start my Jeep. But, I never stood behind it and started it. I think Marlon nailed it. Most people don't look at their tailpipe as they start the Jeep.
