    This is true, but as of right now, the vacuum routing is not right. It was only guessed at by my mechanic. Ford will not look in the archives.

    Thanks for your help. A diagram is what I need. I'm good with all the emissions but finding it impossible to find a diagram that shows vacuum lines from turbo and intercooler and where they go. This is for a 1988 Ford Thunderbird 2.3 Turbo Coup

    Thanks for the diagram. I don't seem to see the vacuum routing for the turbo and intercooler and where they go. Do you have that also?

If intercooler ohocked turbo could hot?

its possible ,are you making good boost pressure? that will tell you if you have an intercooler problem, no boost pressure you have an air problem,check your turbo tubes (rubber hoses that connect to intercooler), make sure your air cleaner is new and or very clean and no restrictions.

Hi mate I have got nissan 200 sx .2001 turbo of my car has stopped working .someone told me there is a leakage in turbo .is it can be fixed .please let me know

Turbo's do not leak as such but hoses connected to it do so check all hose connections and the intercooler for air leaks/cracks in seams /welds . If there is an oil seal leaking it will show up as blue smoke in the exhaust. There is an actuator that varies the turbine vanes to give more boost at low rpm's and this is actuated by a sensor and a rubber hose connected to the vacuum . If the vanes are stuck or the rubber hose is cracked /broken then you will have a vacuum leak and low/no boost at low revs.

Turbo not boosting engine light comes on now and then

turbos that are not boosting may be loosing the pressure from cracked/split intercooler, loose hose clips, split hoses and seized up variable vanes in the turbine side which the actuator tries to work when it gets vacuum from the actuator control module. Check that this hose is not cracked or broken off

Slow slugish turbo

check for air leaks in the hoses and intercooler . Check that the actuator between the end housings is moving the variable vanes in the turbine (exhaust end ). Check vacuum hose to the actuator

Tubro was making 40lbs of boost, now only 20 what's going on

turbos generate boost fro the heat in the exhaust and the free flow of exhaust gases. That means the amount of fuel through the injectors and blocked cat converter or exhaust system. OK now you know how the boost is generated look for areas that will loose the pressure (boost ) between the turbo and the manifold Look for loose boost hose clamps on the turbo and intercooler and intercooler and manifold. Look for cracks or holes in intercooler. Look for blocked air cleaner as turbos use more air through the air cleaner than normal. Finally look at the compressor blade of the turbo as any bent fin will slow down the turbo wheel giving less boost. Have the turbo tested for correct operation

Subaru impreza turbo intercooler drives like normal 2l but has no boost?

I would start looking at your boost control valve and vacuum lines going to your turbos waste gate, as well as the recirc/bypass valve. Usually when cars don't boost they have either stuck open waste gates or recirc valves. Or something is blocking the boost control valve from releasing the waste gate. Also make sure that all your intake hose clamps are tight so they are not releasing boost prematurely.

Blows black smoke when running 2600 rpm and boost goes down

I assume its the 6.0L diesel...If so sigh......double sigh.. I had one of these...triple sigh. I need a bit more clarification. How many km on the engine/vehicle. Also, you say that it blows black smoke while running at a constant speed at 2600 rpm, or while you are accelerating to 2600 rpm. Also, when you say the boost goes down, does it decrease by itself, or when the throttle is let off. The boost naturally goes down when the throttle is released (not trying to be a ****, i dont know how much you know). However, if the boost is going down by itself, while the engine is under load (its not supposed to, it should stay constant) it could be a couple of things, which "can" contribute to black smoke. If there is a leak anywhere from the turbo to the intake of the engine, it will cause the engine to get less boost, which means less air into the cylinders, which means black smoke. Check all of the connectors/tubing coming from the turbo to the intercooler, and from the intercooler to the intake manifold and see if there are any problems. The more costly problems which results in boost going down, and black smoke, deals with a problem with the wastegate on the turbo (controls how much boost is produced, and when too much is being made, it will bleed off excess pressure). So if your wastegate is malfunctioning, your boost will go down and you will get black smoke cause the engine is not getting enough air. also, around 160km...80mi, the injectors "can" start to go on the 6.0L diesels....I would check the turbo for leaks, the tubing for leaks, and the intercooler for leaks (a big rock can punch a hole in radiators and intercoolers...intercooler will be in front of the radiator). I hope this helps
