Fuel traces in EGR Valve.

[fixkick]

Ouch, sry for my mystake about the smoke :/
ok

Well, the coolant level seems quite stable. Yeah, I add it sometimes but not so much (every 800/1000km). But I'll keep an eye on these days.
very good, this.!!!!


The engine temperature seems ok (looking at the indicator atleast). it is only toy this guage, non instrument and not calibrated.
The smoke smells like ...yeah....unburned fuel...and is still present even after 15-20km at idle temp...it raise when I press the gas pedal.
this proves the engine runs rich....for sure. the spark tips may run black with carbon and all hard proof of rich as is gas raw falling out of egr port.
your EFI is cryng for help
MPG is bad, (fuel economy is 1/2 normal like this , is common)

And the exhaust keeps dripping water :/
ever heard of dew point? if the air outside is at dew point , you will see steam, but never a water fall at rear of car. ever.



The exhaust mainfold is broken, it has a little crack. (rear on 8v super rare it is very thing but this crack makes your 02 sensor diead and engine runs super rich. the air is 20% oxygen, so if that sucks into that crack as it surly will that air hits the 02 and it goes crazy....
Another thing is as I pulled off the injector, there was alot of fuel coming out from it...
do no do that , opening a pressurized efi fuel system.
the factory book covers how to depressurize the fuel rails. etc. we crank engine or run it live and pull the fuel pump relay and stave the engine,


I'm thinking to operate those passages:
- take off the whole throttle body to replace o-rings and gaskets (non of this ever cures rich ever (injector 2 o-rings only yes)
- replace the injector with another one I have (as you said the fuel leak when engine is off is not ok) ok, but I bet not it.
- take off the whole intake for cleaning and replace gasket, this will fix 1/2 the EGR path full of carbon, only.
- see if the ECT mounted is the right one and if seats correctly. (yes but test it)
- replace the broken exhaust mainfold with the other one(big time YES)
- check valve reg (following the manual indications...0.15 in and 0.18/.020 out iirc). ( valve lash,yes)

After that should I reg the TPS again? no.

first know that vacuum leaks on this car cause only racing idle
and full power and never will vacuum leaks case rich fueling
except one hose, the MAP hose from MAP to the intake must not be clogged or cracked or the MAP will read high and rich it willl GO.



get a new exhaust ,manifold even used are good. this is first first. thing,or the ECU will never inject correctly.
and a new 02, if not new now. they last 100k miles. =160kmeters.

next is ECT tests,. if not new.
and thermostat must be good and is low life span item. 7 years the top maker of this states, the wax pellet inside goes bad.
