White Smoke / Car Is Smoking White [Merged 7-9]

[Apeximprt2nr]

Alright guys, well I just finished my 14B install in my 95 GSX. All is well besides some minor oil leaks on the return line and the SS feed line at the filter housing. There was also a VERY minor coolant leak from the front banjo bolt on the turbo. I tightened it a tad and I think i went away. Now the turbo is spooling really late because I think there may be a leak before the turbo.
Now on to the problems.

1. The turbo does not smoke at all besides at WOT sometimes it blows out whiteish grey smoke. I'm trying to think of where it could be burning coolant. It never did this before the turbo install.

2. There was some white smoke the past 2 days at the manifold. I'm thinking its the shitload of PB Blaster that I sprayed all over the car but I'm not sure.

3. There's a smell coming from my engine that I can smell if I pop my hood and it becomes more noticeable when I'm driving and really get on it. It smells like burning plastic sort of, with a mix of burning rubber. The lower heat shield is not on the car because it's a pain to get on and I haven't put it back on because I haven't had time. Nothing is touching anything hot so I 'm confused...The only possible thing is maybe I pout on a new 4 ply exhaust mani. gasket as well as antiseize on most of the bolts and the turbo-mani. bolts.

Any help? Thanks.

Even though your in the middle of nowhere go to a auto store/mechanic and get a compression test and leak down test. Mines doing the same thing and I'm pretty sure the turbo/seal is shitting the bed bc my smokes greyish smoke as well. But my compression test came back 165+ on all cylinders. So try that it should narrow it down.

White smoke = Water/coolent
Grey/Black = Gas/Running rich

Are you loosing coolent?
How is the gas mileage?

 

[ConcowTSI]

i believe the smoke is a bluish greyish white. im gunna look round this town and see if i cant find a mechanic thatll do a comp test. also it dont smoke till it warms up (enoguh for the turbo to burn the oil off thats blowing thru into the exhuast im guessing) as far as mileage, my friend has a 99 talon fwd N/A 5 spd and his mileage is like twice as good as mine, however this car is an automatic, so i figure a little worse on lieage but i didnt think itd be that much less!! i will go down and check if its losing coolant but i dont think its coolant smoke. also no water in oil, havent checked the rad cap for oil yet(it was still hot last night), also im gunna check the shaft play on the turbo, should i check any of the hoses for oil or anything wierd?

 

[nated420]

Check intake for excess oil. Also if it starts to smoke when it gets warmer sounds more like a hg than turbo. But compression& leak down test will help. Service limit for compression is 133 , 178 is the best

Just run the damn thing. I wouldn't let a little smoke ruin your trip as long as the car still runs fine. Keep checking the oil and have fun; worry about the problems when you get home.

^^^^^ This


But if no loss of coolent.

The Grey smoke, sounds like you are running rich
I could understand 3-5 mpg worse yours being an auto, but not about half.
Do your eyes water when you stand behind it when it running?

Do you have stock injectors? If not what are you using to compasate for them?

Pull the Vac line to the FPR, and see if it is wet.

I know on a Ford, not sure on a DSM, but when the ECT, the coolant temp sendor for the ECU fails, the ECU defaults to thinking its -40* and dumps mass fuel, causing it to run rich, and poor fuel milage and blackish smoke from the tail pipe.

 

[ConcowTSI]

no loss of coolant, no oil in water or vise versa, you think itd be good for another 400 miles like this, if so, i will try it , it just seems gnarly . imma mess with it in a few and post and update, thanks for all the support guys.

stock injectors as well

took it for a spin, didnt smoke till i drove it for a few mins, the n i stopped at the park, and soon as the car was put in park and started idling it started smoking, went to the parts store and no smoke not even when revving a little, seems like its worse after driving for awhile then idling, or deceleration. also noticed a coolant drip coming from either the turbo or where the oil filter housing that bolts to the block, in that area somewhere, i couldnt pinpoint it ### im a big guy and need to jack the car up a good amount to get under it, took it to the little BS shop in town and he said he would put it on a rack and let me check it out when he got back in 5 mins. waited 20 and got pissed and went back to the motel.

my solution to get it home: screw it like the mod said just drive it. i will stop every 50 or so and make sure the oil levels good and coolant levels good, is it cool to add coolant to the overflow tank when the cars @ running temp? never had to so...? i couldnt find synthetic blend oil so i got two gallons of 10w30 conventional castrol... hopefully with this and a light foot and lots of luck i will make it, but i do have 400 miles to go!

thanks again guys! this forum is freakin awesome; lots of good info and cool peeps here, i especially want to thank those who took their time to call me on my cell and pm me about the 14b i was tryin to find. you will definately be hearin from me.

Sounds like valve seals to me. Some 15W40 or 20W50 should remedy this until you get to your destination.

also noticed a coolant drip coming from either the turbo or where the oil filter housing that bolts to the block, in that area somewhere, i couldnt pinpoint it

Most common spot for a coolant leak in that area is one of the many rubber hoses going to the filter housing.

UPDATE:
WELL I MADE IT!!!
the car just stopped smoking all of a sudden today soon as i started it, since i turned it off, 420 miles and i didnt have to add any oil just a splash of ams coolant boost. car seems to be running and boosting fine now. im going to take the turbo off tomorrow and clean up everything in there and replace any lines or seals that could be leaking, do a boost test, drain and change oil (i dont like the oil the shop used, it seems to thin out basdly, they said it was 76 synthetic blend 5w30. also does anyone know if i have to pull the engine to replace the oil pan gasket on these cars? did on my stang... are denso iridium plugs are good idea for this motor? i had a set and really liked em, but it wasnt a turbo. does anyone know of someone that specializes in automatic trans rebuilds / upgrades for this car? thanks to everyone, and i cannot wait to start tearing my car apart and ordering parts...

 

[JusMX141]

Get that 5W30 out of the engine- that's probably where your smoking issue is coming from....thin oil bypassing rock-hard valve stem seals. Mitsubishi recommends 5W30 only in climates that never exceed 60*f.

 

[O HAI]

Glad to hear you got home safely, the 5w30 could most likely be your problem.

 

[ConcowTSI]

yo! thanks alot guys!!! switched to some 10w40 (it is gunnaet real cold here next month) and NO MORE SMOKE not even on startup, also switched out the auto trans fluid with some royal purple and new atf filter, also have msd wires ngk bpr6es plugs, HID headlights and a gallon of redline 75w90 shockproof gear oil on the way. also my stock intercooler is shit has like 4 holes in it, i was gunna order a fmic but not sure of the size of inlet and outlet and piping size, it has a 14b w/ 1g BOV only getting about 9 lbs(was getting to bout 8 but tightened some hose clampso
i was gunna order a timing belt kit, but theres a bit of noise from the lifters / valves so i am gunna get an engine from pik a part and totally build it, forged internals, possible stroker kit, 272 cams, head works etc etc. that wont be ready till spring tho, should i go ahead and do the timing belt?

Hey there,

was initially going to post this in the Cylinder Head and Short Block forum, until i read their strict rules and it said i'm not advanced enough to post there..

Anyways, i have a 1991 Eagle Talon Tsi with a stock engine and a 14b.

So a couple of days ago i was just sitting there and working on my idle when all of a sudden the car started running lean and rough. I revved it up just a tad and out of nowhere it started smoking crazy!! From everywhere, engine, exhaust, etc.

I pulled the plugs out and three of them are covered in oil. Then i pulled the exhaust mani off and 3 out of 4 exhaust ports are covered in oil.

Now, my exhaust wheel looks amazingly clean, so does the compressor side on the turbo. So i know it's not the turbo shooting oil into the engine.

Did a compression test today and came up with 150, 160, 170, 155 respectively starting at cylinder #1.

The engine does have a metal headgasket with ARP head studs, so i doubt it's that. The compression seems decent so i doubt it's the piston rings. Does this sound like bad valve seals??

Or any other feedback would be highly appreciated before i get myself into buying a new enigne or taking this one apart.

Here are some picks:

you can see three out of four exhaust ports covered in oil

the turbine wheel looks clean (no oil)

You must be logged in to view this image or video.

that's what the spark plugs look like now

You must be logged in to view this image or video.

Like i mentioned above, my limited knowledge is telling me it's the valve seals but i would like some assurance from someone more knowledgeable. Thank you

PS Also wanted to add that when i look inside my cylinder #4, i can actually see a little puddle of oil on top of the piston. I know it's oil because i probed it with a long flathead and it came up with clean engine oil.

 

[92AWDHX40]

Well rules are the rules, but it could be a bad turbo, or valve stem seals especially if you dont know previous records of car. Doesnt look good either way, lots of oil in the exhaust, and turbo.

 

[YZFR1]

Yeah, no worries on the rules..

I don't think it's the turbo because the wheels look good, not oily. Also my intake doesn't have much oil in it at all. So the only other place it could be coming from is the engine.

Compression seems decent for it to be the rings. And it does have a metal head gasket with arp studs.

I also tend to think it must be the valve stem selas. I guess, i just need some assurance before getting into it..

 

[92AWDHX40]

I would tear it down thats just me, could be bad turbo seals, i learned never to say never it could be something you may not think it could be.

 

[YZFR1]

Yeah, i think i might have to tear it down or just get another engine.

I really wish it was the turbo, as a matter of fact, i was hoping it was. Until i took it apart today and my intake is clean. Where would the oil be coming from other than the engine?

I guess i just hope someone could tell me it's just my turbo and why it's doing it..

 

[DixonCider]

Your compressions are all over the place. 150 low on each end with bigger numbers in the middle with oil all over in the cylinder plus white smoke leads me to believe BHG. Mls gasket and arps means little if they were not installed right or retorqued after a few heat cycles. That oil will cause higher compression than it should as the oil will help the rings seal. Old shady car sales men would add a few drops of oil into an engine to make the compression seem good for a short time. My suggestion is going to be to acutally look down into your cylinders and see if there are pools of oil. If so BHG. If ## replacing valve seals your likely pulling the head anyway. May as well plan to replace the hg.

[compression]

This may or may not be relevant, but is there alot of oil on the intake side of the turbo? if any check your intercooler , alot of blowby or worn parts can sometimes turn your intercooler into an oil reservoir.

Doesn't sound like that is what is going on here, but my curiosity sometimes gets the best of me

my intake is clean.

There goes my theory

 

[Funfettie]

valve seals/guides, or piston rings? maybe the turbo its its leaking into the compressor side?

 

[BogusSVO]

I doubt it is the valve seals/guides.... they do not just go from not smoking to blowing smoke, age/wear/improper install is will let them smoke.

Also if it was seals/guides it would be BLUE smoke, looks almost white, but has a blue tint to it.

You are saying white smoke, that would be coolant.

How long did the car idle?
Also did you notice the rad fans cycle on?
How long do you think the engine ran lean?

By your claim of limited knowlage, did you perform the compression test properly? All 4 spark plugs out, engine warm, the TB blocked fully open?

Before this happened my compression was 150's across the board. Yeah, i know that oil raises the compression. As a matter of fact, the lowest compression i have right now is in the cylinder that doesn't have oil.

But yeah, there is a puddle of oil in the cylinder #4, that i can see for sure.
What is BHG??

I also have thought about that. What would cause all three cylinders to just go out like that at the same time?

In my experience, oil also burns white. But either way, it's nothing but oil in there and on plugs, so i doubt it's the coolant..

The car was idling for a little while when this happened. I was just adjusting the idle on the AEM and keeping an eye on the temp. I have a manual switch on the fan at the moment but the temp never went much past 180 F.

When this has happened it didn't run lean for too long before it started smoking. But it has ran lean in the past before.

The last compression check i did was on the cold engine because the smoke was way too much for the car to just sit there and idle in the garage.. But yeah, all 4 plugs were out and TB wide open.


Damn it, i'm starting having doubts now it is the valve seals or guides. The car has been fouling sparks for a while but nothing like this now, having an oil film.

 

[BogusSVO]

BHG = Blown Head Gasket

#1 cyl runs the coolest due to having the waterpump right there, #4 runs the hottest, furthest from the water pump.

Is this the factory engine? ever been rebuilt or swapped out? How many miles on it?

Ahh new info... been fouling plugs for awhile.... How long? oil foul or gas foul?

I am starting to think cracked or collasped rings, oil would seal the cracks and give a false compression reading.

You need to run a leak down test.

 

[YZFR1]

Interesting information!

It is a swapped out engine. As far as, i know it is stock but might have had a head rebuild, probably has about 100k on it.

Looked to me like gas foul before this happened. But the compression was 150 across the board before this happened. Could it still be cracked or collapsed rings?

I'm starting leaning towards just getting another stock engine but i'm still thinking about it.

 

[BogusSVO]

Now that you say it is a swapped block, are you sure it is a turbo short block? or could it be a NA short block?

Quick check down the spark plug holes, and see if the pistons have a T on them, should be a 63TD for a turbo piston and just a 63D for NA pistons.

The ring gaps are diffrent between the turbo engine and NA or NT engine.

I would say the head has been thu a shop in the recent past, it is too clean and has a satin finish to it, like it has been glass beaded.
