Lean mixture problem: Turbo

[perfworks]

1. 18,572 miles (1500aprox turboed)
2. I dont have any oil pressure gauge nor restrictor, will take pics in a few minutes.
3. Yeah center housing was upside down when installed and ran like that about 20-30 miles. This was corrected, running perfect until 2 days ago. This is the only reason I see that could have damaged the seals.


Starting Today, this car will be stopped for the following 2 weeks until I solve all mayor issues, including clutch. Will take this time to install rear awr mount and remove those secondary intake plates....if the money reaches

DO NOT REMOVE THE SECONDARY plates!!! it will KILL your bottom end.
the VTCS plates yes, remove them but not the VICS.
well i forgot you had run it upside down. overheated and ruined the seals.
get the ones from spoolin and get boostin again. you will need to get an oil pressure gauge for future use to make sure everything is ok.
If you need help on the plate removal let me know and ill show you how i did it. or send it to me and we can fix it for you. maybe port and polish while its apart

Yeah, I was talking about the VTCS, Ive never seen the VICS. Refresh me, the VTCS are the ones that open at 4700rpm right?

And...about the port & polish....sounds interesting, how much you going to charge me for that job?

the VICS (variable inertia charging system ) is right after the plenum before the runners. You cant see them unless you take the manifold completely apart.
The VTCS ( variable tumble control system) is located right by the head port and tumbles the incoming air charge to atomize the fuel on cold starts for lower emmisions . they open at 69 degrees F. the VICS open at 4750 and will send the ecu into open loop at that point.

If you pay for shipping i will do it for $85 us dollars. It will consist match port and polish, remove the VTCS plates and plug the actuator. This will improve air flow and gas mileage while cruising.
anyone else that may be interested and has the set up can send it also. the down time will be same day on my part and depending on the type of shipping .
PM me or email if interested.

In regards to the turbo rebuild I am pretty sure there should be a garrett repair facility in Puerto Rico (The home of turbo freaks )

If not you can send it to me and I could get it sent off for you. Let me know

Heres the picture of the setup, and an attachment of the turbine close up.

I have another question...is it normal to see vapors comming out of the valve cover outlet?

 

[perfworks]

umm what kind of vapors?
from the side of the cover?

 

[igdrasil]

umm what king of vapors?
from the side of the cover?

From where you put the breather...(the filter)
Check the picture
I think is oil vapors...like if they were burning inside and expelled

If your car is not overheating and you have vapors coming out from the side of the valve cover it could be bad news.

You may have broken a piston and/or piston rings.

I hope not.

 

[perfworks]

to tell you the truth igdrasil i have never actually SEEN vapors of any sort come from there. granted it is designed to replumbed to the intake so you wont normally see it, but if it's not excessive then i would think its normal. im not trying to be vague i just cant really help if i dont see exactly what is coming from there. sorry
maybe someone with the same problem (or normal condition) can comment

 

[igdrasil]

Ok heres the picture!
I hope for good news, but, this is the first time i see this, and, this picture was take after 1 min of engine started, so ts very cold.

Igrasil,

Vapors comming out from there is not normal at idle because all the vapors should be going into the intake manifold thru the PCV valve in the center towards the back in the valve cover. The pcv valve splits in two into the intake.

I hope for the best. If you can, make a leak test for all cylinders.

I haven't heard the thought of a blown head gasket! Could that be the problem?? It almost seems like it??

How are the vapors comming out forcefully? From the pics that what it looks like.
How is your idle?
What is your vacum reading at on the boost gauge?
What color is the smoke?
What does it smell like?
When does it do it?

From a quik observation it does not look normal at all. I know you were overboosting to 20psi and possibly you could have initially damaged something. What boost are you running now?
Have you heard any detonation, ping, knock?
What were your EGT's maxed out in 3rd gear? What is your Greddy a/f reading at WOT?
Sorry for all the questions just trying to diagnose.
I would also reccomend a compression check for piece of mind

 

[spoolinmp3]

If the smoke is white, and it comes out like a smoking cigarette then you may be in some luck. This is common. Get your compression checked.

EDITED

Boost is like 6-8psi...no joke, but maybe those overboost or maybe the Leaning issues may have damaged something and now Im noticing?

1. Smoke comes like a cigarette but just because of the filter, its trapped inside and comes out slow. If i leave it without the filter, it almos streams into invisible. But on close look you can see the stream.

2. Idle is perfect, from 20 to 22.

3. I think the smoke is white, and smells like gasoline and oil, I dont know, I kept trying to figure out the smell it too long...i think im stoned (stoned) hehe

4. The smoke is always there, always, cold start, idle, accelerating...you name it. Maybe needs an oil change? nah

5. Never heard ping or knock, wastegate noise could have hidden it because its too loud.

6. I never had EGTs over 650C, (probe on downpipe 1-1/2 inches from turbo)

7. Sure I will check the compression, thats easy, but what numbers should i see good?

8. The turbine is leaking oil, confirmed

 

[b_real45]

I think on car's with a 9.0:1 compression you should see around 180psi per cylinder.

igdrasil what spoolin recommended is the only way to get the diagnoses correct. I would suggest getting it professionally checked.

 

[igdrasil]

Engine Repair Manual says Compression on FS engine is:

Standard: 171psi
Minimum: 119

But the maximum difference between cylinders should not be over 28psi.

 

[spoolinmp3]

We checked compression on the MP3 and we got 170 across the board.
Anxious to here your results

 

[igdrasil]

BAD NEWS!!!

Cylinder #1: 155psi
Cylinder #2: 92psi :mad:
Cylinder #3: 165psi
Cylinder #4: 163psi

:'(
Got pictures of the compression gauge.
Now, straight to the point: This is decisive...

Should I go forged? Or sell everything and go N/A?
If I go forged? What would be the weakest link now? And what will I need after I get forged?
