SOURCE: 4Runner headlight has moisture inside. Light works fine

yes. it should be a fairly easy job, just be careful when removing the glass, and make sure you get your headlight re-alligned when it is done, as it will fail its mot if not done.

hope that helps.

SOURCE: 1991 toyota 3L V6 Overfueling, raw fuel pouring out exhaust pipes

The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.

I need to remove the exhaust manifold on the right side of a 94 4.9l engine in a cadillac deville. It has a broken bolt in the exhaust. What is involved in removing the manifold?


I suggest you use all new exhaust manifold hardware and torque new bolts to 20 Ft Lbs.
4.5L and 4.9L Engines
RIGHT
Disconnect the negative battery cable. Remove the air cleaner. Remove the exhaust crossover pipe. Disconnect the oxygen and coolant temperature sensors. Remove the catalytic converter-to-AIR pipe clip bolt. Remove the upper manifold-to-cylinder head bolts. Raise and safely support the vehicle. Disconnect the converter air pipe bracket from the stud and remove the converter-to-manifold exhaust pipe. Support the engine cradle with screw jacks and remove the rear cradle bolts. Loosen the front cradle bolts and slightly lower the Engine cradle. Remove the remaining exhaust manifold-to-cylinder head bolts, the AIR pipe, and the manifold. Clean the gasket mounting surfaces.
To install:
Install the exhaust manifold and replace the AIR pipe. Tighten the manifold mounting bolts to 16-18 ft. lbs. (21-24 Nm). Install the manifold-to-converter exhaust pipe and replace the converter air pipe bracket to the stud. Raise the Engine cradle and install the rear cradle bolts. Tighten to 75 ft. lbs. (102 Nm). Lower the vehicle. Replace the upper manifold-to-cylinder head bolts. Replace the converter air pipe to AIR pipe clip bolt. Connect the coolant temperature and oxygen sensor connectors. Replace the exhaust crossover pipe. Replace the air cleaner and connect the negative battery cable. Start the Engine and check for leaks.

How to replace the exhaust manifold ring in my 91 Toyota Tercel


There is a bracket that attaches the exhaust pipe to the engine block. Remove the 2 screws that hold
that bracket on. I think they are 12mm heads. Detach the 2 exhaust manifold to exhaust pipe screws,
the screws have 15mm heads. A 15mm deep socket is best. After you remove those 2 15mm screws you can pull the exhaust pipe down, remove the old exhaust flange and put the new one on.

Rettach the exhaust manifold to pipe screws, and reattach the bracket and youre done.

1995 4Runner: coolant coming from exhaust pipe?...


Coolant coming from the exhaust pipe is a common indication that you have a blown head gasket. This is a fairly common problem on 4runners equipped with a 3.0L V6 engine. I do not recommend driving the vehicle in this condition even if it is not yet overheating because it can lead to serious engine damage.

I have a 30lite kzte diesel and had to replace the cylinder head for the second time .The heads tens to crack on the no4 piston


you need to get a mechanic that knows what he is doing. The head has to be shaved and the head bolts have to be replaced and replace all rocker ball valve assemblies to stop the head failure, you are aso having a over heating problem on that cylinder which could be an injector or a plugged exhaust pipe.
