It could be possible, sound good, to good but it's the second time that I checked the waste gate flapper and seems to be seating good;

I'm using av-gas 100/110 oct and something special happened when we use that gasoline, is very easy enough to see if a exhaust leak is on the stuff, because the smoke on the swing valve or turbine wheel or exhaust manifold even in the moffle pipe is white not black, so in my case the turbine housing hole seems to be full sealed.

Are you saying that you are able to make a visual inspection of the puck sitting against the bypass hole with the car running? Try not to get burned. OUCH. Seriously though, drop the downpipe...when its cold get a flash light and apply some regulated pressure to the actuator. Make sure it operates properly and does not hang up. If it appears to operate properly make sure the puck covers the hole completely. Disconnect the actuator, open the valvee put some grease around the bypass whole and then close and open the puck. Did the grease transer all around the puck? The only other thing I can think of is a crack in the turbine housing or a boost leak somewhere else. Do you know how to do a boost leak check?

my turbonetics turbos never had a seal either. I'd assume its a machine-fit. Looks like you need to pressure test the wastegate and piping.

I have heard of leaky turbonetics before and people sealing the backplates with rtv silicone. I would re-assemble and look for the leak. Oil has no business being there either.

What are you using for an oil drain tube?

-the inspection that I did was with the turbo down.
-good suggestion or tip talking about the grease.

actually my turbo was leaking air pressure when the first pressure test for the backplate and the compressor housing, it was due to it doesnt have seal.

Pull the the blow off valve and plug the hose and then test it to make sure its not malfunctioning

[tryingbe]

What are you doing for PCV valve?

[shelbymonster]

what it seems to be for me is the swingvalve valve is not sealing tite on the housing making a wastegate leak , i would do a boost leak test too

[Shadow]

When you put the W/G actuator on the turbo, how much preload did you put on the S/V arm? ie. If you take the clip off of the actuator arm and seperate the actuator from the S/V, how far would you have to pull the actuator out to get it on the S/V again?

[The Pope]

^^ that could be it. Thing may just be sloppy, just not enough tension on the flap to keep it shut.

is done, same thing.

around 1/2 " of distance, actually it was too hard have to pull the actuator in to get it on the S/V again.

**well, the conclusion it could be between s/v an s/v actuator.

**and how about the turbo inlet compressor oil??? that isn't normal, nobody told me nothing about the oil.

**the turbo is new only maybe 300 kilometers on it bought it on April.

turbonetics says that sometimes is normal due to high oil pressure on relanti but my oil pressure bomb is almost brand new original Melling and the oil pressure indicator is ok

[tryingbe]

How is your oil catch can setup?

Any oil in your intercooler?

[jim34]

How does the turbo spin ? and how does it sound, can you hear it whistle when its boosting ?
