Installed new TD04 turbo and vehicle ran perfect for a week or so. Last night drove 10 mins it is revving to fast and when i looked at exhaust manifold it was glowing red.

I would check your MAP or MAF sensor to be sure. Sounds like you are running lean which is causing your exhaust gas temperature (EGT) to be very high. Running lean with a turbocharged car will destroy your engine very quickly. Drive the car gently until you figure this out.

Also, it is common for the exhaust manifold and downpipe to glow orange if the car has been driven in a spirited manner. Although, normal (not lead foot) driving shouldn't cause your EGTs to be this high.

I have a Mazda cx 7. The turbo needs to be replaced. Can you just disconnect the turbo?

It is not really possible to "disconnect" a turbo. Its bolted to the exhaust manifold and all the exhaust gas is routed through it. you would have to try to find a header or exhaust manifold the was built for that car and not designed to run the turbo. Even if you were able to do this you would still have to have someone advance the timing back to where it should be for a natuarlly aspirated engine and re program the computer / change fuel enjector sizes to get the air fuel ratio back to ideal. (running without the turbo would cause your engine to run rich with fuel and cause engine fouling problems not to mention poor fuel economy.)

Nissan Navara STR 2006 d22 3lt turbo. Turbo is whistling very

Remember, what is heard as turbocharger noise may not be caused by a noisy turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration and increases or decreases with rpm and load. This condition is most often the result of a loose clamp/hose at the turbocharger compressor outlet, charge air cooler inlet, outlet or at the intake manifold.

1. With the engine running at idle and the transmission in Park or Neutral with the parking brake set, feel for boost air escaping at each connection between the turbocharger compressor outlet and intake manifold. For limited access areas, spray soapy water on those connectors and look for bubbles.

2. Check the exhaust manifold and exhaust system for leaks.

I hope this helped.

Thank you,

How do you remove a turbo on a toyaota rav 4?

Turbo's are attatched to the exhaust, coming out of the exhaust manifold in the engine bay, regardless of whether it is a diesel or
gasoline engine. There is a oil hose attatched, usually, and about
2 or 4 bolts holding the round unit onto the exhaust system. Good
luck. They are about a few thousand $$$, so be careful.

Hi, what does it mean when huge amounts of white smoke comes out of the exhaust? otherwise drives ok? it is a renault megane 1.5 dci 2004. regards catherine

Symptom: White smoke or water vapor from the exhaust. You notice white smoke coming from the exhaust when you start your car. If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem. Possible causes:
  1. Transmission fluid may be entering the intake manifold through vacuum modulator.
    The Fix: Replace vacuum modulator
  2. Cylinder head gasket(s) may be bad.
    The Fix: Replace cylinder head gasket(s).
  3. Cylinder head(s) may be warped or cracked.
    The Fix: Resurface or replace cylinder heads. (Resurfacing is not a DIY job)
  4. The engine block may be cracked.
    The Fix: Replace engine block.

What does code 52 means on the toyota corolla 2000 model in SA.

DTC 52 on a 93 Corolla is a Knock Sensor code. I replace the knock sensor; it is located on the side of the engine block, on the side of the engine that faces the firewall. It is in the center; under the intake manifold.

Thanks for choosing FixYa for assistance.

LC Prado 2LTurbo engine,turbo is not boosting.

check the piping from the compressor outlet to the throttlebody for boost leaks. also check to make sure that the wastegate actuator is functioning properly. it may be stuck open. the other thing to check for would be an exhaust leak either between the head and the exhaust manifold or the exhaust manifold and the turbo.
if its none of those things, check the blades on the turbo (compessor and turbine sides) for damage and make sure that it turns freely
