It could.
Generally a sign of burning oil
No. which manifold gasket are you wanting to replace? Intake or exhaust?
The cable was bad. The shift cable had come loose from one of its mounts and was resting against the exhaust manifold causing it to melt the plastic housing and the cable began to stick.
It is mounted in the exhaust system. Start at the exhaust manifold and work backward toward the catalytic converter. It is more than likely mounted in the exhaust manifold right at the engine. It may also be mounted where the two exhaust pipes come together.
To replace it remove the battery terminal so you will not have power. Loosen the bolts (use liquid wrench or wd40 for this will be rusty) exhaust pipe from the exhaust manifold (driver side) and then you need to loosen the exhaust pipe from the exhaust manifold to the part where it connect exhaust pipe from the other side of the exhaust manifold (passenger side) and then you need to loosen the electrical wire from the starter and then loosen the bolts that connect the starter now you can wiggle the starter to pull it out you need to try to figure out how to get it through the loosen exhaust pipe ( but it should come out)
If the exhaust pipe, muffler, or tail pipe have come loose, you will certainly hear the rattling, but that would not be the cause of the shaking. It is something else causing the shaking, ranging from bad tires to bad engine performance.
When the driver let's off the gas pedal going into a turn raw fuel gets pumped into the exhaust manifold. The manifold is so hot the fuel ignites and you see flames from the exhaust pipe. It's totally normal.
This sensor varifies flow of the exhaust gases to the intake manifold. If flow is interupted the sensor will inform the onboard computer that the exhaust recirculation system has failed resulting in a check engine light to come on.
my rear cat won't come loose(rusted) what's your advise
The O2 sensor is on the drivers side exhaust manifold. When all four exhaust pipes come together from the manifold that area is called the collector. The O2 sensor should be right there. If your looking for this and you get to the catalytic converter you have gone too far.
Since they are really the same thing, there is no answer. An exhaust manifold is a header and vice/versa.The common cast iron 'exhaust manifolds' are quiet, last forever, and cheap to produce. The headers you refer to are more expensive, short-lived and can be very pricey. But the first guy who bolted a pipe on the exhaust post of his single cylinder motor to keep from getting burned by the exhaust created the first header. He also created the first exhaust manifold. Take your pick.
