SR still smoking and not running right

figured its time for a new thread, but heres the old one for refererence
http://www.sfldrifters.com/forums/showthread.php?t=68658

basically the cars still quick, but feels like its missing power
when i first start it up, it idles at like 1.5 and almost 2k if its cold, and when i press the clutch in to shift the revs jump UP instead of dropping down. thats probably something separate but it could be related to the smoking problem

according to my friends when im driving, it doesnt really smoke much, but it does smoke white a little, and when im hitting it, it only smokes a little bit of black. But at pretty much every red light i get to, ill come to a stop and see a huge cloud of white smoke just blow past my car, and i see it in my rear view mirror just straight POURING out, looking like an asshole and getting my smoke in other peoples windows

and every now and then ill get to a red light and it will only smoke a little bit, that i can see in the headlights of the car behind me, but not enough to fill the area with a cloud of smoke. So id say half of the time its like this, and the other half of the time its like a fog machine

a lot of people are saying turbo seals, but my turbo was fairly new when i put it on, and i already checked the intake pipe and the hot pipe for blow by, and its all dry in there, no oil

i know my piston ring on cyl 3 is worn because compression on it is 135, but i change my oil often with 20-50 and use that "engine restore" product, so its holding that off for now. the smoke smells like oil, but every time ive done an oil change, the oil level hasnt dropped since i put the oil in from the last change, so its like its burning oil, but its not


all this being said, its tough to figure out why its smoking so much. I doubt its the turbo seals because theres no blow by, and even though the smoke smells like it could be oil, my oil level on the dip stick never drops, or atleast not enough to notice

anyone here got any ideas, or would be able to take a look at it?
 
does your coolant level drop?

i just have water, not coolant, but the radiator always stays topped off. The reservior gets low after a few weeks, but its not like its burning through it rapidly. I did the "swirly milkshake oil" head gasket test two oil changes ago, and its just straight oil, no water swirling on top

dude get a turbo quit fucking around its the first step.

like everyone else here, im hurt for money, so id rather not spend $80 on a new turbo and go through the PITA to swap it just to find out it didnt change anything. What other ways can you check if your turbo seals are bad?

for real bro?
yeah, from what ive read up, if you have blown turbo seals you will get a shit load of blow by and oil in your intercooler piping and your intake pipe



also, when the car smokes, from the side mirror it seems like it "pulses" smoke for about 4 seconds at a time, as opposed to being one long steady stream of smoke
 
So lets say there are exhaust gases getting to the intake side and mixing with the fuel and air not allowing a clean burn and thus causing your car to smoke not even taking into consideration w.e problems u Have. That can possibly be Turbo seals? There are more seals then just the oil journals fyi. 2) back to basics. white smoke = water being burned. black= too much fuel not all getting burned. blueish= oil so check ur coolant n do a leak down test ( and if u smell gas in the radiator u should know what's up) . If u want it fixed u gotta do something other than say what u dont think is wrong but not do what everyone is telling u.
 
i thought blow by was piston rings or clogged crank ventilator... whatever u say man good luck... get a new t25 its not like your running a really expensive turbo!
 
turbo has a rear seal wich is leaking into the exhaust, front seal is prolly still good

i know peeps are broke but u gotta pay to play
 
he did say that one piston ring was worn.. would that not cause the smoking issue?

last time i checked it was either turbo seals or piston rings.. not many other options for bluish smoke that i know of..

the black smoke is acceptable when you're hitting the gas.

are you sure the white smoke isnt blue??

the t25 i have now was in really good condition when i put it on. It had no shaft play at all in and out, and barley and i mean BARLEY any shaft play side to side (and from what i know this is normal to have minimal side to side play). I havnt checked it again, cause its a bitch to take that inlet off with all the stuff i have in the way, so i have to wait till i can jack my car up at my friends house, take apart some stuff and make room to get down there and check it

also, unless i know for sure its the turbo, i really dont want to have to go through the pain in the ass of swapping it, not to mention spending the money to buy it, just to see if thats it, and probably find out that i just wasted my time and about $100 that could have went tward something else

Also i dont live in a house with a garage anymore, i sleep on my moms couch in her condo and my car stays in a guest parking lot. So unless its something minimal, any time i want to work on my car, its a complete pain in the ass because i have to drive it about half an hour to my friends house, and thats only if i dont have work, and he happens to be avaliable

Not really too sure, im no mechanic, im just learning as i go with this shit like most people on here. As far as getting a new t25, if it was quick easy to do and i had the place to do it, i would honestly suck it up and swap it out and see if it does anything, but like i said above, its a complete pain in the ass to do any work on my car

the other thing is these turbos are more than 15 years old, if i buy a t25 from someone on here its probably blown as well lol

unless i know 100% sure that the turbo is fucked, im waiting untill i have enough for a GT28rs

+1 dude honestly from all the threads you have made it seems as if this SR just doesn't wanna work. get a new one.
I have another long block with resurfaced cylinder walls, new piston rings, and new seals all around, but i dont know whats up with the valvetrain/head noise i was getting before i pulled it out and put this SR in.

Its most likeley something really stupid, but its sitting in my storage unit behind a bunch of shit, and its gonna be harder to diagnose the problem with it out of the car and not running or anything. But my plan is to take the head to a shop and have them figure out what the deal was, get ARP studs and a thick ass head gasket, and put this one in the car and swap everything over to this block when i have the money/time/place to do all this

It looks pretty white to me, i dont notice any blue in it. Which i guess is wierd. I dont know what burnt oil smells like personally, and i dont have a good sense of smell either, but my friend that rides dirt bikes a lot knows his smells and he says its oil.
 
From what I saw late that night we checked out each others' cars it was pure white which means coolant/ water...

NOT oil. So diagnose coolant

how else can i do that? ive already checked what the oil looks like and its fine.

if it helps anyone figure out whats up
The coolant temp sensor was bad, which was confusing the ECU and flooding my engine, to the point where i had to unplug two injectors to start it, but thats been changed

ECU reads "55" (no error codes), and the oil light went away after changing that

unfortunatley it didnt do anything for the car smoking, and yes ive changed the oil since then
 
heres what i think you should do... sell me the old block you have, so that way you have money for whatever your going to fix!
 
coolant goes to the turbo.....................

good point

but ii also noticed, when i get to red lights, if i dont let the car try to die out and keep the revs above 900, i doesnt really smoke at all

but if it dips down to like 300 and pops back up, a bunch of smoke comes out afterwards

i used to think it did that because of a vaccuum leak somewhere that i couldnt find, but now im noticing that the dying out goes hand and hand with the smoke (in some cases)

i dont see why it dying out would have to do with the turbo though, so im wondering if its sputtering, dying out, and smoking because the compression is so low?
