Did I waste 4.000?

[liquid2gst]

Before i begin let me state that i hope im posting my question in the correct fourm.
second, i've been searching this site since may of 07 when my probs first began to help narrow down my issue,but at the time i wasn't a member so my answers seemd limited.
and last but not least i totaly respect how the system works and i am fully aware that i should search the site to find similar probs to maybe help mine..witch is a good idea but i think i have a little more then meets the eye going on with my dsm so here we go.

I just bought my 3rd gst,this one i wanted to build from the ground up.when i bought the car it was just the body,no motor,no tranny.nothing.before buying just anything i read the tech guide on this site for increasing horse power on a 2g dsm,and choose my parts wisely
i bought a used motor with 30,000 miles(or so i was told),spankin' new tranny,stage 3 clutch masters clutch,brand new radiator,all new hoses and piping,big front mount intercooler,custom piping,20g turbo,obx headers,3 inch down pipe straight back no cats,greddy exughst,turbo sx m.b.c,ngk iraiduim plugs,ngk wires,new starter,new alt,greddy turbo timer,greddy boost gauge,greddy type s bov(vented),new battery,im running ams oil,my vac pressure is at a solid 20,and im only boosting about 17-18 pounds.until i upgrade the head more.

problems..after the car being in the shop for about 3 months(once i bought the car i took it to a well know tuner in my city and they put the car together and supplied the motor)
i was told the car ready,they cranked her up,she sounded sweet.one prob..white smoke came billowing out the tail pipe like crazy,they said it would go away after a while.this was in may of 07.i took her home she felt great almost like a new evo.no b.s,the smoking died down a little but it never went away.2 days of driving her i noticed the car would over heat
very quickly(30 mins of driving) i also noticed smoke comming from underneath the hood,
i found my oil line from the turbo to oil pan was leaking,on to what? i dont know.i over looked these issues for 1 day and it all went down hill from there.i took my ride home and let it chill for about 6 hours,got in again and it didnt over heat after 30 mins so i thought the car was fine. i lost all electric,my car over heated,and the cops show'ed up,i luckly got her started and jammed outta there she had no time to really cool down for over heating.once i made it home she shut down on her own,wouldnt start back up.thought i had blown the motor,so i left her there to die..alone went inside and shut the garage.the next day i tried to crank her up,she did on the first try,but now i get constant white smoke
and she over heats after 30 mins.

probs:OVER HEATING,NOT HOLDING CONSTANT BOOST(SPIKES TO 18PSI DROPS TO ABOUT 13-15 WITHIN SEC'S,WHITE SMOKE FROM TAIL PIPE,LEAKING OIL FROM TURBO OIL FEED LINE.

sorry for such a long winded post but i wanted to be very clear on my problems,hoping to get a desent response on what my problem is,i've spent alot of cash on a car that ran good for i'd say 3days tops,shes been sitting in my drive way for 7 months now,still cranks right up,still smokes like hell..thanks to everyone in advance and this site rocks.

sounds like the head gaskets bad and your burning anitfreeze becasue of that

white smoke is always burning antifreeze
black smoke is to much fuel or running rich
blue smoke is burning oil

yup sounds like you have a blown headgasket. DO NOT LET THE CAR OVERHEAT. You will begin to warp stuff then your really in trouble. If you decide to get a metal headgasket, make sure the head and block are machined properly.

I was told (and beleave) it's the other way around. White is oil, blue is coolent.

nope white is coolant, blue oil, black fuel

 

[turboglenn]

Yamaha4life had it right. Coolant burning produces white smoke ( condensation in the exhaust wil cause this too when you first start the car for the day, and it's more common when it's coler out)

BLue smoke is oil burning

Black smoke is a rich condition

I agree, it sounds like the head gasket is shot or you have a crack in the head. This would cause your over heating as well. As for the turbo feed line. Where does it come from? The oil feed off the head or from the oil filter area?

 

[yamaha4life89]

while the head gasket is being replaced inspect the oil feed line to the turbo make sure theres no holes if so replace it look at the banjo bolt make sure theres two copper washers one on each side of the bolt and make sure its tight and just replace the gasket between the oil pan and oil feed line that should fix the leak

 

[zatomz]

When I blew my headgasket I had a gigantic cloud of white smoke which went for 5 or 6 blocks and then the car just died.

not to beat a dead horse, but head gasket.

now, to your problems:

1. oil return lines break all the time. they suck. i'm fabricating a stainless line for myself, hopefully a write-up for it will be coming soon, i'm waiting on some parts. replace the oil return line. they sell ones at forcedperformance and extremepsi for like $100. or wait till i finish mine and it'll probably cost a lot less.

2. overheating is probably a headgasket. headgasket also explains the smoke. blue = oil, black = rich condition, white = coolant. check inside the oil cap for milky or foamy oil, and in the coolant for globs of black stuff (oil) floating amongst the coolant.

3. sounds like boost creep/spike....i didn't see listed anywhere that you had an aftermarket 02 housing, i would get either a 3 inch 02 housing or get an EVOIII unit and port it to 3inch. the EVO3 units are heavy, esp. compared to some of the stainless ones out there. also, port the turbo if it's not already done. port the wastegate or think about going external.

Boost creep & boost spike are completely different issues & should not be referred to as the same thing. What your response to was boost creep & this doesn't sound like the issue the OP is describing. It sound like he is just seeing boost spike, which a few psi spike on initial spool is fairly common & nothing to worry about. Depending on which boost controller your running, this can be worse. I too ran a turbo XS mbc at one time & was seeing large 5-6 psi spikes depending on the gear. I swapped to a Joe P MBC & that reduced the spikes greatly. If you want zero boost spikes a good electronic boost controller will do the trick, obviously at a much higher cost.

Think its been covered fairly well, but yes sounds like a head gasket issue. Do a compression check & go from there. As other have said, make sure you don't continue to over heat the car as you will start to warp things & make things much worse. What kind of head gasket are you running? (maybe swapped to a MLS & it didn't seal properly?). Have you checked your antifreeze, is there any oil mixing in it?

Finally, if you've been searching around here for awhile you should know that street racing & talking about street racing isn't something thats allowed (& stupied )

thanks for all the response's,i too belive i might have a blown head gasket,now that i have some advice and great answers from other vet.dsm owners,as far as i know i dont have milky oil,but i havent ran the car since may i have started it everyday since though just to keep the motor use to being cranked,i will check my anti freeze right now to see if there are any signs of what most have described,as for the boost it only spikes up to my set boost when i get on her.and just dosent hold a constant 18psi like i thought it would,once she reaches 18 she drops to 13-15 area..thus losing a small amount of power.
the oil feed line is comming from the turbo going into the oil pan,the shop that put the turbo on said they couldnt use the after market oil line so they used my stock one and so it leaks i just cant figure out where the oil is leaking onto to cause the smoke to rise from underneath the hood...after my first post i was kinda inspired to give my gst another shot at love..so i went out side to check my thermostat to find that the thermostat had been removed..it wasnt there,maybe the shop forgot to put it back in?,amd could the fact that im running no cats strigt pipe cause smoking to?

This thread's on a downward spiral... if there are any more references to street racing, it's getting locked or trashed.

There are other forms of racing, ya know... only a small fraction takes place on the streets: dragstrips and speedways are legal alternatives.

 

[daren_p]

so just incase im the only one that street races or has street raced their dsm (witch im sure im not) could someone please tell me why would someone spend endless amount of money on upgrades and not use them?what purpose do you guys build your cars for?
and i think you guys should be happy my put together dsm smoked a $22.000 sti.
how else do you find out if all the tech support and how to's really work,unless you get out there grow some nuts and try?

Thats an easy answer, we push the limits of our cars AT THE TRACK! I'm sure some members still do, but it is right in the forum rules to not talk/post about street racing. Street racing is pointless & dangerous & it's not always the people that are racing that are the issue. There are so many incompatint drivers on the road, that its not worth the risk. Not to mention if your caught doing it here, your car will be impounded on the spot for 7 days you'll get a min $2000 fine (up to $10000) & have your license susspended & yes this is all on the spot, before you go to court.....


First of all what are you running for a fuel system & what are you using for tuning? If your still stock in this area, then its a good thing your not running 18 psi constantly as you'll be looking for a new motor. The stock fuel system won't provide enough fuel for that turbo at 18psi. If your hitting 18psi on initial spool & after gear changes & then it dropping to 13-15 area within a few second/hundred rpms, thats just boost spike. Your actual MBC is set at the 13-15 range & just spiking to 18psi. Like I said if you on the stock fuel system, it shouldn't even be set this high.


No, running no CAT & straight pipes shouldn't cause your car to smoke.


For the oil leak, jack the car up & get under there to take a look to see if you can find the source. If your not able to find the source, wipe it all down & then look for the source. Could be the gasket at the turbo side or the gasket at the pan side but more then likely its coming from the return line flange to oil pan bolts. These aren't sealed from the oil in the pan & use a crush washer on each botl to sel it. Most of the time people don't realize these washers are sealing washers & don't usually work when re-used. You can pick up new aluminum crush washers from the dealer or a copper srush washer from your local parts store will work (believe its 4mm size).

hey thanks alot darren p...your the ish.and guys/mods please dont take me for a nobody num nut
im fully aware of the consiquinces of street racing...i've only dont it once or twice(witch is prob to many times),i usally watch from a very far distance hehehe but as a man its kinda hard not to be tempted by the streets and the growing urge to prove whos the fastest..and i fully understand that proving who maybe the fastest is the easiest way to prove to everyone else whos the dumbest when you get caught..im sorry for my refance's to racing and as long as i am a member of this fourm i'll do my best to stay within the guidelines set by the creators and mods.i have nothin but respect for you guys and i most def.dont wanna get off on the wrong foot..im very truthful and i dont try and change my words around to acomadate anyone especialy when talking amoungst men..witch im quite sure most of us are.
if the mods see fit to trash my post then so be it but i'd like to thank all that did help me and my dsm re'establish or new found relationship.i promise to have her up and running with a few pics and vids of her progress..and to everyone that gave advice thanks you guys rock.

I was told (and beleave) it's the other way around. White is oil, blue is coolent.

It's rule #3 of posting: Don't try to help if you don't know the answer - bad advice can be worse than no advice (no "I think" or "I guess" or "I've heard").

And +7 for blown head gasket. What did the shop say about the billowing white smoke? Unless they offered to fix it for free, I'd seriously consider taking it elsewhere to get fixed. Any shop that'd let you drive off like that (or not test driving it first) is in my book.
