hello,

first: I have searched al lot ;-)


setup

stock engine
GT35R single turbo
everything is removed

intake:

- no filter on the turbo
- after the turbo there is a hose on the pipe for the wastegate.
- intercooler
- BOV
- elbow
- throttle body (no coolant connected)
- UIM with only 3 map sensors connected to it (no PVC)
- LIM with 2 secondary injectors

I still have the oil injectors


PVC in not connected to the intake, it is vented outside

the setup is brand new... engine is stock.
it only is running at idle and some small throttle lifts by hand.
first it was smoking because everything was new... now it is not

I tapped the oil and it smells a little as bezine.... because it flooded once.
no coolant in the engine oil

the oil filler neck it is vented and also on the secondary turbo oil return hole on the engine is used to vent.


there are some issues i want to understand

1
when the throttle body is off the primary intake runner in the UIM is wet inside.
It looks like a oil and coolant mix
the UIM side of the throttle plate is wet to.
the elbow side is clean... elbow and IC piping is also clean


2
exhaust manifold is a little greasy


what is possible:
is this because a little exhaust/intake overlap ?
bad oil injectors ?
to much fuel because it isn't mapped yet ?
other explanation ?


sorry for my bad english

 

'benzine' => 'gas'/'fuel'

 

that's right !
it was a sunday afternoon

 

Let's see if I can lend a hand, As for the wet primary runners... Where are the oil injector fresh air hoses attached to. The rubber hoses not the oil lines They "should" be attached to the filter side of the turbo. However , since you do not have a filter on it, you can just vent them to the atmosphere. They should NOT be getting Boost pressure at any time. Mine were hooked up to the UIM when I bought the car. Went thru 3 sets of injectors(oil) before I figured out what was blowing them up and gushing oil back into the UIM. My primary runners were very oily due to this. As well I fouled plugs about every 4k miles or so.

Now, your exhaust manifold being "greasy"... I believe that has something to do with the rear oil drain/return being left open to "vent" If I am understanding it correctly, When the car underwent the change to Single turbo. Someone left the rear turbo oil return port on the engine Wide open with NO blockoff plate.. Correct??? If so that is why your manifold is greasy. That return port should be closed off. I don't exactly know why anyone would think they should leave that open to vent. That is what the PCV is for ventilating the crankcase.

The oil in these cars will almost always smell of fuel. Just the nature of the beast. Obviously it should not be overflowing fuel and thinning out the oil.

Hope that clears up a couple issue or helps out at least.

I ahve made eerything myself... so I can not blame someone else :-)


on the oil filter is a small solenoid filter.
So vented outside


The greasy stuff was in the exhaust manifold.

I think I found the problem.. it was running way to rich at idle.
it couldn't even idle.

now the exhuast manifold is dry inside.
