So, I took the car out on test drive to see how it would run and to get my exhaust done. I know I wasnt supposed to hit boost, so I tried to keep it down. Well after shifting is my bov suppose to go off? Even if I dont hit boost? So after this, hoping I didnt hit boost, because my boost gauge didnt even go into boost. So am I okay? Well any way my car started smoking so I checked under the car and I sprung a leak with the coolant lines. I'll have to redo the lines tomorrow, but Im just a little worried I messed it up.

yup.
my blowoff valve goes off well below the boost threshold., depends on how you roll in and out of the gas.

Okay, I was almost crapping on myself. Well, do you think the smoking might have been the coolant leak?

x2 on the bov thing... Your bov will go off all the time you shift. you might not have boost but you do have pressure in your manifold where your vacuum line comes off of. It regulates itself and releases the pressure built up when the throttle body butterfly closes.

Hmm lets see....... yes!

yes the bov will still go off. the turbine is still spinning, in fact it spins at idle and as soon as you close the throttle body the turbine just having that spinning inertia will push "pressure" out.

alright....sounds good. I gotta fix the coolant leak tomorrow, then get my exhaust done. And tuned Saturday. Lets hope I won't spring another leak.

Okay, its been a few days since the turbo install and now I'm a little concerned with some problems. I have scheduled some dyno time on Monday, but need some help on diagnosing some issues.

1. I keep getting white smoke out of my tail pipe. I'm a little concered with the head gasket now, but I don't get any of that milky stuff in my oil or have oil in my coolant lines.

2. I looked on the compressor side of the turbo and spotted a tad bit of oil. So I just whiped it up with my finger.

3. At idle, how come my oil pressure gauge is reading at 40psi? SHouldn't it be like 20? And after getting my exhaust done, I noticed that my idle would fluctuate and my oil pressure gauge would bounce up and down.

4. How come at idle I am at like 2K rpm. My boost/vacuum gauge is reading a little over 20 vac.


Any help would greatly be appreciated. btw, I am not tuned YET.

the high idle is becuase your not tuned yet. your running bigger injectors...so its rich. the oil pressure should be around 40ish at idle. as far as the oil in the turbo...it's your seals...depending on how much it burns from the tailpipe when you boost will determine how bad it really is. vac reading is normal...mine reads the same.

But wouldn't blue smoke mean that my turbo is bad? I'm getting white smoke.

when i wasnt boosting in my car, it was smoking alot. my problem was that my intercooler pipe wasnt connected to the turbo so it wouldnt boost...so what i did was connect it and took the spring out of the wastegate...also might be that you need an oil reducer.

I have an inline reducer already. All the pipes and everything hooked up properly.

does the smoke smell like coolant?

I'm not sure. Lets just say at stop lights the car smokes really bad. And when I shift a huge puff of smoke comes out. I figured it was the fact that I routed the hose from my pcv to the intake manifold. So I routed into the intake from the turbo and capped off the intake manifold nipple. But still smokes.

ya it's your seals....unfortunately. did you buy it from a member on here or is it an ebay one.

I bought it off of mr2oc. Btw the guy never gave me my money back for the map sensor I paid for, but what ever. Its not like I can get my money back now. So the white smoke is my turbo seals? I always thought it would be a head gasket issue. Isn't the smoke suppose to be blue if its the seals?

If in fact my seals are really gone. Where can I get my turbo rebuilt and for how much normally? Not looking to upgrade anything, just want the factory specs.

I sent mine to majestic turbo and it cost about $300, and I had it back in less than 2 weeks.

Alright, I guess I'll give them a shot. But it just sucks with the fact that my car will be down for even more time. Damn, really pissed.

So I came out to the car today and noticed that I had some residue on my muffler. Whipped my finger on it and it totally smelt like a mixture of gas and oil.

So I was googling my issues and this is what I found.

if the engine is running rich you would be pumping black smoke, unless it is REALLY dumping fuel, then the white smoke would be the unburnt fuel burning when it hits the header, also your header would be bright red if it were running that rich and you would have like no gas mileage.

Qouted some guy from a honda forum. Am I really running that rich?

I'm going to get tuned tomorrow, and hopefully this issue will go away, but this has got me worried. I mean I'm getting like little tiny droplets of liquid on my muffler. Smelled it and it was straight up gas.

^ what do you expect will happen when you put it much larger injectors on an ecu thats programmed to control smaller ones? You need to get the car tuned.

...and make sure both your pcv and idle hoses are hooked up to the intake, before the turbo.

yea, if your not pulling out fuel, especially at idle and low load situations, you'll be just rediculously rich.

I routed the pcv tube to the intake from my turbo and capped off the tube on the throttle body. Ain't i supposed to leave the pcv valve alone? And what idle hose?

Even when I was driving to and from to get my exhaust done, I had a redicilous amount of smoke coming out the whole time.

what are you using to tune the car?
are you pulling any fuel?

I'm using the AFC neo. I thought I pulled enough fuel with that write up someone did on the forced induction page. How much should I bve pulling out at idle?

I think i pulled about 28% at idle. is that no good?

okay, checked my settings and at 800 rpms, I have it set at -39%. Still smoking like crazy.

Okay, took the car to get dyno tuned on Monday and got some bad news. Well the guy tuned it run a lot smoother now, but couldn't finish the tune because I have no boost. My car won't go into boost at all. So the tuner told me to look at my injectors because that could've caused the major boost leak. Got home took all my injectors out and found out that the one he thought was leaking was actually leaking due to not having an o ring on there. I could have sworn when I put my injectors in all of them had all the seals and rings on there. So any way I replaced that o ring and no more fuel leak. So I took it out and still no boost. I hear the turbo spooling up just fine, but the car just won't go into boost. Where could I be leaking that bad to not make any boost what so ever?

I checked my wastegate actuator arm and its still stiff. So could it be due to an open wastegate. Should I just pull the turbo and see whats going on? I mean I don't hear any major leaks like before. Someone please help. I've put sooo much money into this project and its just not running the way I've always dreamed it would be running.

So I decided to cap off my other wastegate nipple just to see what happens. Still no boost. And my bov won't even go off any more. Well I do have an ebay bov. I decided when I first got it to take out one of the springs. When I did that my bov was going off like crazy. So after awhle I thought that just having one spring was giving me leaks. So I decided to put on the other spring. Driving the car around just to see what happens bov went off fine. But after the partial tune no BOV or boost. What could be the case?
