My 1998 spider gs-t smokes and it’s annoying and I am pretty sure it’s most likely the turbo seals I feel like, It only smokes when I rev but never when I’m just in idle. I thought it would be the valve guide seals but the guy I bought it from said he had gotten them replaced and they didn’t look eaten up when I had my valve cover off. Just want to be sure before replacing the seals on my turbo. Is there other reasons to why it might be smoking? Any feedback is appreciated.https://www.youtube.com/watch?v=IoNgI0KIQ3I
 
You got something a little different about your boost control. :idontknow:
okay thank you for your help though :( let me know if you have some sort of an idea of how it works

edit: also this brings me back to my initial dillema of it smoking, if my boost control system works, could it be the the turbo seals after all
 
I had one of those like 7 years ago it's an ebay deal. I'd just get rid of it and run wastegate for now. I'd also move your bov closer to you throttle body and run that vacuum hose that's going to it. The recirculation hose looks like it's kinked and that will cause problems to.

Okay, which one is the recirculation hose? Also how do I revert this back? Can you point me in the right direction. Thank you very much its appreciated.

Get your cc vent rerouted first. See what happens.

I'm not a 2g guy, but there must be a nipple somewhere else pre-turbo for your boost control bleeder hose. If I'm not mistaken, that's the bleeder hose attached to the cc vent port. Not that it's mechanically wrong this way, but you need another port.

Okay, so take the weird little air filter and connect the two with a hose and then I'd find a nipple somewhere for the other hose thats currently plugged into the maf area?
 
The boost control is very strange to me. The filter off the VC is a downgrade vs how the factory did it. That went factory to the intake pipe so it used the vacuum created pre turbo when in boost to pull crankcase pressure out. When using a manual boost controller you just use a boost only source like a nipple on the turbo or inter cooler pipe for source and other side to waste gate. They are just a simple bleed valve. The super long line off your intake manifold i think is what the factory used for the BOV. The stock PCV valves on these cars by now leak on most we see. There was a company that made a cheap inline check valve we used to put inline between PCV and intake manifold years ago. Maybe was US plastic corp or something for the company. 95% of time over the last 15 years someone has brought me car thinking turbo was the cause of smoking it was not. Valve seals will usually smoke on start up and deceleration. I always first pull exhaust manifold and if exhaust ports are dry on head its not seals. Then if turbo is set up correctly for feed and drain, then breather/ pcv set up. Turbos that do not have excessive in and out play usually only smoke when there is a drain issue so oil can not drain from the center housing. Usually its a breather issue. I have seen it bad enough on a motor i built that someone who did not know set up the breather set up so badly it made enough crank case pressure to push a main seal out and soak the clutch.

Wow okay thank you, I think it's strange too and I didn't notice until now. My question is that when I remove the breather filter off and replace the factory hose. the hose that was connected to the intake that is also connected to my BCS where would that go? and I have been looking for a diagram or something explaining the BCS hoses on a stock gs-t. If you can find that or give me insight it would be super helpful.
 
Stock there is a electronic boost control solenoid mounted on the rail under the intake. This gets source from boost only and then goes to wastegate. You can as said put a source line straight from boost only to the wastetgate and it will make just wastegate presssure. You always want the source to be boost only and not from intake manifold that sees vacuum. This is for any kind weather it be nothing but line, manual, or a electronic solenoid. I have never seen someone use the vent port off a solenoid or manual controller ran to a intake pipe for vacuum. I am sure there is nothing wrong with it but have never seen that.
 
Has anyone thought to have the OP unhook the pcv valve and plug it's vacuum, as a test? The valve could be letting oil into the intake, making it smoke. It would only confirm if it is part of the problem or not and be temporary.
 
also, doesn’t the top nipple of my wastegate solenoid supposed to go to my intake nipple?
 
so I had a little breather filter on my cc instead of the stock hose connecting to the intake. I want to put the stock hose into the intake so the pressure releases and doesn’t smoke anymore. but where the hose is supposed to go into the intake it is already being used by the wastgate solenoid, i believe it’s called, and so what should i do? is there another nipple i can plug either one in?

Thr solenoid goes to a nipple on the radiatorbside of that pipe. You've got the hoses routed incorrectly. Whatever white adapter thing that is not an oem piece. On the firewall side you have the big bov return, intake vent, and vapor cert from cannister. On the radiator side is boost solenoid return. Total of 4 hoses. Take the snorkel off the car and it will be obvious. All 4 connections should have a male connector sticking out you can slip a hose onto.
 
Here's the 2g intake snorkel that pretty clearly shows the three ports/nipples. Red is the boost control bleeder. Yellow is the charcoal canister. Orange is the CC breather. So see if you can find the red port that faces the radiator and move your boost control there.

Thanks to https://www.tgilmore.com/talon/dumptube.html for the image. A few more on that site if you need more visuals.

i also do have a bov connecting to the left side intercooling pipe at the bottom, would that be where the nipple you’re talking about be? or is it somewhere else. pictures would help very much i’m not too familiar with some of these like the bov return, vapor cert, and the snorkel, sorry in advance

The bov return is big. Like an inch diameter. The small vacuum hose on the bov doesn't go to the intake snorkel anywhere. I mistyped. Vapor return. The snorkel (intake pipe)is the entire rubber piece from mass air flow sensor to turbo. If you want a good look at it take it out of the car.

okay thank you that helps, i’ll take it off and i’ll see the lines, there should be 4? i’ll send pictures when i have it off
 
His bov and recirculation tube are a mile away from where the factory location should be. That caught my eye out of everything. I'm guessing the new thread is him trying to figure out the smoking separate to the all the plumbing going on.

yes just trying to fix the smoking right now, i’m trying to figure out the plumbing as well. i’m trying to return it to stock a little at least but i don’t know how different it is since i have a bov.
 
That vacuum hose going from your intake manifold, if its going to your bov I can't tell but thats right it's just all stretched out because of how low your bov is. Check your other thread there's a diagram there for you and if you still have the sticker under your hood there should be a diagram there also.

it is going to my bov LOL and thank you
 
okay so i replaced it and the picture that showed the three hose nipple on the air intake was very helpful LOL and so i reconnected everything correctly this time and it’s still smoking, i let it come to operating temps, nothing was leaking or anything, the only weird thing was that in the exhaust there was a little bit of liquid dripping, you can see in the video, and it still smokes after throttle

edit: also i had my snorkel/air intake off and checked for shaft play and there wasn’t any play.

edit: also does this mean that there is still too much pressure buildup within the cc?

edit: sorry for the edits but as i think more questions come to mind, and this is unrelated but when i throttle and let off my rpms dip below the normal idle rpm and then go back up to normal
