Default (Resolved) White Smoke, Under 3k miles.

For those of you who have seen some of my other threads/posts, you'd know that I'm very detailed and unfortunatly, this means that it's going to take a few minutes to read. I do this because it prevents people from asking questions that could have been clarified in the orginal post.

Let me say for clarification that the main reason I'm posting this thread is because I'm paranoid about any symptoms that could mean ringlands. I've been down that road, so anything that might mean a costly repair makes me cringe. Here's a quick rundown: The bottom end was built and assembled by Robert at Foced Air Technologies. Forged pistons (stock bore), brand new case halves (obviously machined) I-beam rods and a stock crank. I broke in the engine occording to their recommendations. The car was also tuned by them after completing break-in. I started noticing issues when there was around 500ish miles on the block. At first, it was a small cloud of white smoke, which did not worry me because it was intermittent; Sometimes it would be on a cold start, sometimes it would be after I got done driving for 30 minutes, stopped to get a drink, and fired it up. It seemed to come and go as it pleased, I would say for the past month I didn't seem to notice any smoke AT ALL.

Today I picked the car up from FAT (they were sorting out issues with the a/c as well as misc. other things) and the cloud of white smoke is back. Didn't do it leaving the shop (motor cold). Went to work, came home, ran errands etc and didn't notice anything. However, after going for a short (5 min) 'spirited' drive, gassing up and chatting with an old friend for 15 minutes and starting it up, a nice sized white cloud, almost like seafoam came out. It DOES NOT smell like coolant. The cooling system was pressure tested at FAT while it was there and it held pressure fine. Hoenstly, it almost smells like E85/Alcohol (car is obviously on corn ).
Important details on the car: The turbo is orginal (100k miles) and about 1k of those miles were on 23+psi of boost. This was due to the External wastegate being routed incorrectly, I've personally seen the stock llamco boost gauge COMPLETLY maxed out for short periods of time . Bear in mind this was in 110+ degree temps. Another thing to note was that the car was on dino oil for close to 2500 miles, car has no turbo timer.

I'm pulling the tmic out tomorrow to clean the oil out of it. I was just wondering how much would be considered a 'normal' amount of oil and how much would be considered 'excessive'. I have a suspicion that the turbo seals are shot, and I will add pictures tomorrow of the I/C to verify this. If anyone has any other recommendations on things to check or what to look for, please let me know. Also, I pulled off the oil filler cap a few months ago after noticing the smoke, and there was no smoke coming from it whatsoever. As always, I appreciate similar stories as well as input and advice. Cheers

Possibly turbo seals are bad, also depending on brand of pistons if a piston ring was installed up side down it may cause excessive blow by.

Pretty sure they are CP's. Pulled off filler cap today, again no smoke. Didn't get a chance to check shaft play on the turbo today. The car definatly doesn't feel as fast as it did before. Going into 3rd and 4th, it just doesn't pull the same. GRRRRR

Ok guys, the car smokes upon startup everytime now. Cold, warm, hot doesn't matter it still has a cloud of white smoke coming out. I've verified with 3 different people that it does in fact smell like oil, and not like coolant. I'm at a loss here. Took it for a drive with a buddy of mine and he swears up and down it feels just as fast as always. The car is not making any weird noises at all. And Methaddict, I don't think it was the rings installed upside down because the engine builder commented that the rings were upside down originally (I bought a built shortblock off of the classifeds that turned out to be un-usable, so they tore it down and started from scratch) so I'm going to go out on a limb and say that he didn't put them in upside-down. If that were true, it would have done it all the time from the get go, or one would think at least. I just don't understand how oil could possibly burn white?

Pull your down pipe off and look for oil. Check your intercooler pipes for oil. Get a compression and leak down test.

Phantom smoke upon startup is typically 99% of the time a bad valve seal. They are very easy to damage upon installation of the seal its self and when installing the valve. If you don't have a pool of oil in your exhaust and downpipe its probably not the turbo. If you had ring issues (especially installed wrong), you would see smoke in the oil fill tube and have crazy crankcase pressure and it would smoke more than just at startup.

I'll pull the downpipe next thursday, until then I work everyday. Thanks for the replies.

*Edit, I just got off the phone with FAT and they told me not to waste my time doing anything and to bring it down Monday, and they'll take care of me. Just another reason why they will keep getting my business. They're not even going to charge me!

OP's prob sounds like what happened with my closed deck motor, i was told later it was bad valve guide seals, so I agree with crystal, to either bad valve seal/ piston rings didnt seal/break in correctly (maybe)

my car on random cold starts, then later was more often with most of the everyday usual start ups, would puff out a huge cloud of white smoke and box the street for a small period of time, it would stop smoking at no more then a min, but ive been told when i drive away or people thats seen me drive either reg throttle or full throttle, that it smoked out the exh a little during normal driving and a good amount when I was on it, also saw in mirror could barely see other car I was against at the time

Yeah, that's kind of what I'm leaning towards. Oddly enough, the car sat overnight and it did not do it this morning on my way to work at all. I let the car idle for a few seconds after driving it. The oil level has not moved, nor has the coolant. I might just replace the pcv valve. It did however smoke when I started it up leaving work today.

Alrighty, I figured it out. 2 weeks ago, I changed the oil and added 5 quarts instead of the 4.6 or whatever it is thinking it would be no big deal . Yesterday I drained the oil until it was at the 'full' mark and resumed driving the car as usual. It started smoking less and less, and after a few good WOT runs, the car no longer seems to smoke. Thanks for the help everyone.

That is odd unless you have a large amount of crankcase pressure which is backing up the turbo return and causing the smoke. I always fill to 5qts and never had random smoke problems except for the one time I misinstalled a valve seal. I would do a leak down test just to be safe. You could have a ticking time bomb.
