7afte questions Options

[CelicaST18]

So i followed NIK's How-to on the 7afte. Got everything all hooked up and took it for a spin. I was makin about 6.8psi and it was fast. Until i got to about 4000 RPS, at which point it felt like it was bogging down. Oh, and there was a lot of smoke. Does anyone know what could be wrong?? I have sat here for hours thinking on it. If you have ANY input at all, please, input it.

did you prime the oil through the turbo before running it?
is the turbo new or used?
what turbo did you use?
what color is the smoke?
can you list your set up i need more detail in order to help

blue smoke is gas black is oil so youre rich do you have any way to control the fuel ? the bogging might be your too rich and cant burn it in the cylinder is your fmu adjustable? if it is turn it to 10:1 is the smoke only happening about full boost?

[CelicaST18]

i don't have any way to adjust the fuel...the smoke happens all the time though

oops your right

ok so oil

pull off the IC pipes and see if oil is in there if so a seal in the turbo is gone if not check for blow by you might be pushing oil past the valves and what oil are you using?

what is the size of your feed and return lines on your turbo?

right if you have to much pressure you'll force oil pass the seal also and if your oil drain line is too small it wont drain right

[CelicaST18]

no oil in the i/c pipes...is it possible for a seal to be damaged on the turbine side of the turbo?...I am using pennzoil high-mileage 5-w30....

[CelicaST18]

did you use pcv valves for the check valve?? do you have a picture of the check valve???? or a diagram...i want to make sure i made it right..i have this feeling that that is causing the bogging

I was thinking the same. oil drain. also, where did you place the return line on the oil pan? you might try putting a breather filter on your valve cover vent instead of having it run into the intake. That added pressure on the valves might force oil past the valve seals.

its like the manifold valve yes
i just sent coomer a bunch of pics for more detail in the 7afte
there just plain check valves for the map
i think you might be getting blow by pushing oil from the valve cover in the intake manifold i have a little oil breather bottle that might help you if its that the problem you hook it into the line between the intake manifold and valve cover
can you post up some pics

[nik]

with me ,edo,fallen ,and hanyo on it well get it fixed this is what i like about 6gc.net over any other site

[CelicaST18]

the oil drain line is the same size as the factory turbo drain line...i have a breather filter on the valve cover...the oil drain line is a little higher than where NIK had it

[FallenHero]

so does it smoke all the time or just at 4k+?

[CelicaST18]

I fixed the bogging when boost came on, the check valve was backwards..oops, the MAP sensor was not damaged...Unfortunately the somking problem has been solved (hopefuly only temporarily). I need to have my car and can't try to fix it, so the turbo is off the car. However I know what i need to do to fix it. The turbo is blown and needs to be rebuilt/replaced. After driving it for a while, oil finally worked its way into the intercooler pipes. You can't imagine the disappointment I felt when I saw that. Also, as I was looking at the set-up, the oil drain line MIGHT come out to high. It comes out the side of the turbo (below the oil feed line) but I think ewhen I put it back in i might as well fix that whether it is or isn't a problem....Thanks Nik and others for your prompt help....I love 6GC.net!!!
