I wasn't calling you dumb, I was saying letting **** break for no good reason is dumb. When I said that I was assuming the car had the stock CARB legal cat installed. While it may not be required in a particular region, the cars ability to be legally operated in any state does effect the value of the car. Hence my comment about the non-compliant replacement, It is not a true replacement for a fully legal CAT.

 

Bought a turbo rebuild kit from turbo lab, hopefully do this next weekend.

I pray I don't snap any bolts.

Hey, I noticed you are in NY and you track. I'm planning first time at lime rock late august. Any suggestions or tips? thx

 

1.) Bleed the brakes and replace with some quality high-temp fluid. This is #1 for a reason.
2.) Swap pads for something higher-temp for track. I like Carbotech XP12, this is like politics...everyone will have an opinion.
3.) Make sure your cooling system in working order (never loosing coolant on the daily).
4.) Go your OWN PACE with your OWN LINE at the track.
5.) Don't run the fuel tank below 1/3 or so on gasoline.

 

Tried pulling the turbo this weekend. Didn't get far.

Noticed that the flex portion of the ETS DP rusted through.

Snapped a few bolts on the header

Pretty sure the stock manifold is cracked, its 08, w/ 50k miles.

So i put everything back and going to bring to a shop.

Anybody know if there is full list of all the bolts sizes used in the engine bay and exhaust?

I want to swap out all the bolts to SS, they are all rusted and some really bad.

 

Hey guys, great news. Because of the smoke issue I took the leap and upgraded to MHI 18K turbo with 1000cc injectors. Tuned to 402HP!!!

The Bad news: Still smoking. Any thoughts? This is really sucking big time.

 

You say you have catch cans - as in plural - have you ever looked into that aspect of your setup to see if it's contributing to your issue? Since you've eliminated the turbo and checked everything else, I'd start working my way top to bottom with oil related items. What type of setup do you have? Why do you have multiple?

Aside from that have you looked all the way up and down the exhaust for anything stuck to it that would heat up and start smoking / smelling like you described? If it only happens after a while, seems like something getting heated up then seeping / hitting the exhaust. Have you seen any marks that indicate something like that? I'd drop the exhaust and see what the top looks like closer to the engine, see if you can see anything.

Do you know if the smoke is coming out of the exhaust itself or just billowing out behind you? Can you put a camera on the car / under the car to see when driving?

 

Hey, thanks for the reply.

I have catch cans on both sides of the PCV vented to air. I don't even remember the reason why. it was one of my first mods years ago and i remembering reading about the benefits on this forum. However during the tune, the shop un-did it and put back the stock re circulation but its still smoking.

As for something stuck in the exhaust i guess its possible but during the turbo upgrade i also swapped the downpipe from ets to ams. I have no cat, just a resonated test pipe and a specialty x cat back.

to my understanding, white smoke is generally " supposed" to represent coolant getting in and burned and Grey/Blue smoke is suppose to represent oil getting burned. It could be a combo of both.

 

RECAP - STILL SMOKING A TON

1. About a month and half ago started noticing a lot of Mostly white (maybe a little grey) smoke billowing out from exhaust intermittently. But still pulled hard. No noticeable loss in coolant or oil initially.
2. Initially thought that it only occurs during WOT or Pulls but eventually noticed that regardless even on normal DD to work, shifting at 3k and avg 45 MPH nyc traffice it would still smoke. First smoke of each day would generally occur around the same time or distance driving to work. Interesting pattern.
3. Thought it was perhaps turbo seal, so spent a 3-4 weeks procuring new turbo, injectors, and some other minor items.
4. Had a shop install it 2 weeks ago, picked it up and drove it back (20 mins) sat for a week and drive 2 hours to tuner this saturday - No Smoke.
5. During tune, Smoke did occur thought maybe some residual oil stuck in the resonator? I have no cat.
6. Made 402 HP on new tune, did 2-3 pulls after leaving tuner. smoked.
7. 30 mins later in heavy traffic on the way back starts smoking. no hard driving since leaving tuner.
8. Monday, drove very careful to and back from work, yes smoke. oddly starts right at the same point as before turbo upgrade.
9. Tuesday - Drove to work and back. No smoke. odd. It was cooler day don't know if that has anything to do with it.
10. Wednesday - light pulls during commute - yes smoke, lots - people kept pulling up to me to tell me. again very intermittent
11. Today - Same.

Any insight is greatly appreciated.

Thanks,
SL

 

Put a catalytic converter back on? Lol - still think you should drop exhaust to look for splatter - unless when it was on the dyno you saw the smoke pouring out of the exhaust directly? Do you take the same route to work? Any other cars smoke in the same area like maybe there is something on the road? Youv'e got an odd one esp since you've been worked on so much and nothing found.

 

Hey guys, just want to post an update.

So about 100 miles ago, I added some lucas stop leak oil and it seems to help. Noticeable less smoking. Maybe a puff under harder driving. I think it maybe the valve stem seals? at least thats what i've read. The key or culprit was probably due to a 2-3 year gap where i did not drive the car . The lack of lubrication and winter months probably caused the seals to fail prematurely.

While on the subject, do you guys know of anything else that could be caused by extended period of non-driving? So that I can pro actively look into it? e.g. belts, chains, and etc?

THanks,

SL

 

And fyi if its useful, I only have about 44k miles.

 

You should really get this diagnosed by a shop.

Not trying to internet diagnose your car or anything, but if you just google "cause of white smoke from exhaust" you will see the 3 likeliest causes are head gasket, cracked or warped cylinder head, or cracked cylinder block.

 

I mean, both oil and coolant are mostly closed systems. Keep a REALLY close eye on both levels and you'll know what you're burning.

Valve stem seals typically present when the car is cold started, when it's been idling and you transition to throttle, or when you go into high vacuum (long coast in gear on the highway or down a hill) and then transition back to throttle.
