: Blue smoke normal on startup?

I'm really serious about getting a new 2007 SRT-8 from a local dealer. When I looked at it today for the first time I noticed about 10 seconds of blue smoke from the exhaust when the salesguy first started it. It only has 22 miles. Is this normal? I loved the way the Jeep drove but am willing to hold off for another if this indicates problems ahead. Or maybe this is normal while beaking in? Any ideas?

If it was blue smoke than that is oil being burned. Nothing but the normal hot exhaust in cooler weather when I first started mine up with 4 miles on it.

I've never seen blue smoke from mine either. There's no reason to take the risk, IMO.

No blue smoke here,Had a weird smell first few miles and some slight engine prep smoke but it was definatly gone before 22 miles,move on to the next one you will find one with no smoke.

Cold weather white smoke is normal, blue smoke in any weather is bad, she is burning oil.

Thanks for the advice. It was about 35 degress outside but it was definitely light blue smoke and not white. I watched the cloud of it travel across the dealer lot when it was started. I'm only a couple of hours from Chicago and it seems there are options to buy over there.

Many options in the Chicago area. But remember, after you buy it, its the Service that counts.

Like the others have stated, blue smoke is oil burning. Given the low miles, the piston rings are still seating in. During this process, it is possible for the rings to line up or be positioned in such away as to allow a bit of oil to burn. If it were higher miles I'd be a bit more concerned. My guess is this will go away with break in.

It may have something to do with the exhaust being new, I noticed on the Corsa exhaust install instructions there is a note stating that there maybe a trace of smoke after the initial start-up...citing that the smoke is caused by the burning of the forming oil residue that is used in the manufacturing process. I would assume that this should not be a ongoing issue after a couple hundred miles.

Cold start-up, around 38 degrees. About 600 miles so far. First time I've seen it but it puffed a sizable cloud of blue smoke. That much oil shouldn't be getting around rings at this mileage should it? Otherswise, its oil in the intake, shouldn't that be a dealer problem?

I have had that situation since day one. Here is when it happens. I start her up, 5 min warm drive away....no smoke. Ever! I start her up, back out of garage and shut it off for the big wash job...restart...smokes the blue for a bit everytime. Go figure.

I've seen blue smoke come out of mine too for a few seconds on cold startup with very low milage (under 150) so i would guess its normal. Also, I noticed it was only coming out of the left side and not both. ???

today for the first time after three years and 30k miles I experienced this phenomena :) i turned my truck on for like 5 to 10 seconds in order to move it like 10 feet then after couple of hours I turned the truck on to go somewhere and freaking blue smoke poured out like nothing else like I did a burn out or something... it's weird ... never seen it before ... :eek:

yea blue smoke is burning oil thats deffinatly a problem...if your riding and you see blue smoke usually your tran is about to go

If we need catch cans to keep oil from entering the intake, wouldn't it be acceptable to recognize this blue could be oil blown up into the intake and burned? My '08 did this at the dealer 2 days ago when I bought it, it was close to -40c/-40f outside, it was stored inside my heated garage and spent maybe 1 1/2 hours out in the cold before being brought in for cleaning. I fired it up and got a cloud, after a few seconds it was gone. Blowby past the rings this substancial would require adding oil regularly to the crankcase to keep the levels up. I have no consistant coloration in exhaust, oil level change hasn't been noticable on the stick, and I haven't seen it since. If I had some pooled up in the intake, parking somewhere not level could disturb the pool allowing some to burn to one bank of cylinders, maybe I'm rambling, I dunno, I just find it hard to equate the blue to being ring blow by when we need catch cans to begin with.

I bought an 08 which had been sitting for along time....there was considerable water condensation in the muffler...upon start-up it blew a little smoke but was transparent after warm up. If you go to the other SRT8 forums they complain about the same quirk. Believe it is a characteristic of the motor....it would be interesting to note whether those who installed oil catch cans have the same issue....

Blue smoke maybe twice upon start up after sitting a bit in garage. After catch can install in 07, have never seen it again.

Little water/condensation in tips on start up some times depending on temp/humidity, but stops quickly.

blue smoke = pass on that srt8. old cars should burn oil not newer ones, think back to the first car many people owned, it probably made blue smoke, and it was probly a piece of junk

Not really,Turbo Porsches and Ferrari flat engines will do the same....I concur that if the smoke is constant then you have an issue......I believe there is some benchmarking to rely on. Several owners on this GCSRT8 forum and many on each of the other SRT8 forums(Hemi 6.1L related) have discussed this matter. It does not appear to be an isolated problem. I would start one up at the dealer test drive it -turn it off and re-start....if it belches smoke again then I will agree with you....

NEGATIVE..........CATCH CAN....... and the smoke on start up goes away. This is my 2nd Jeep and the oil blow by sets up in the manifold and is ingested and POOOF.....blue smoke.

That appears to be the consensus....I just bought the DCX promo with the catch can and Predator.......

here is a summarization for you so you can weigh your options and see what it is. Logically, you want to listen to people with a good rep and credibility here and that one is sarge and he stated getting a catch can which I agree 100%. The smoke is a 100% result of oil burning in the cylinder upon combustion and there are two main culprits for this. One the lack of a CATCH CAN is letting oil gather in your intake and fly into the cylinder upon start up and once it is burned out the problem will cease. The purchase of this CATCH CAN will fix the problem if this is it. The second culprit is the fact that it is still so low miles, as stated, the rings have yet to sit into position 100% exactly and it take some running of the motor for them to heat and expand or "fit" into place 100%, I doubt this is the case though as the amount of oil that would get passed these seals is very little to none but not to rule out. I believe I'm 95% sure its your lack of catch can so I wouldnt pass this up because you think it has a problem as there is no way thats the case, the motor is fine, it is no "lemon". No SRT8s have ever has a serious problem brand new such as this that I've ever heard so I'd ask the dealer to throw on a catch can, clean out the intake manifold and maybe spray in some cleaner into the motor to clean t out and re fill with oil than with the catch can have them cold start it and run it and see if the problem persists. From here if you see it, I'd ask around, do some homework on some other SRT8 options. This should solve your problem though, GL with finding the Cherokee you want, you wont regret the decision ;)

Well stated and I agree 100%. My 06 started smoking after 5,000 miles....I totally freaked thinking what the heck:confused:...this is a new vehicle. The 6.1 is a well built engine and I have never heard of any engine requiring replacement of any component due to this this condition. many of us who started removing our manifold to install spacers found the oil saturated manifolds and head ports to be the culprit.

The Corvette and GTO guys have had the same problem for years and we stumbled on their issue along with the AMW and Elite catch cans they were using first.

Still happens once in awhile with almost 5k and a frequently emptied Billet Technologies catch can.
