Do not drive it. It sounds like you have a stuck valve and a stuck open thermostat. It sounds to me that a valve has been stuck open allowing combustion to overheat your manifold. Or you have an obstruction of your exhaust. Normally the valves are timed in such a manner that combustion occurs and your exhaust valve opens. In this case that a valve may be stuck open or the seat/face is damaged, your combustion is being directed right into your exhaust. Does the vehicle run like it's missing, lacking power? I would recommend doing a compression test which is very easy. Rent a compression tester from Schucks or AutoZone. Remove one spark plug and thread the appropriate fitting into the block. Remove the coil wire from you distributor. Have someone crank your engine for about 5 seconds and watch the gauge when they stop. It should hold steady or drop very very slowly and only a few psi (like 5). Write down your results and replace spark plug and move down the line. If you measure the compression on cylinder one at 160, cylinder two at 155 and so on (the numbers flop around a bit. Usually around 10-15psi of each other) then the valve is not the problem. However, if you measure one of your cylinders considerably lower or dropping considerable quick, you may have this problem. If all checks out, I would use a SeaFoam treatment to expell smoke through your exhaust to check obstruction.
If it's glowing red you have a vaccum leak someplace, probably in the intake manifold or the engine is running lean on fuel or possibly too rich as the unburnt fuel is burning in the exhaust.
It could be running lean. Check the fuel filter. It could also be a vacuum leak or the EGR valve. It would probably be a good idea to not run it much until you've worked out the problem. There are quite a few possibilities, and some of them are not very expensive, but if the exhaust manifold is getting that hot you could be damaging your exhaust valves. If the exhaust manifold is glowing, it's not the cat-converter.
Are you trying to remove the exhaust manifold,the muffler,or just the line running from the manifold connection to the muffler?
It's a turbine mounted in the exhaust manifold to give more power and smoother running to the engine.
squeeking from exhaust manifold is caused by a leak allowing exhaust gas to leak. it will only get worse as time goes on unless it is fixed
A leak in an exhaust manifold will be very loud. The car may also experience issues stalling or running to lean since the oxygen sensor readings will be off.
No but an engine running like that can damage the valves.
Loud engine noise is usually a result of a hole or disconnection in the exhaust manifold or muffler.
If it is running loudly then there is an exhaust leak either at exhaust manifold or some where else in the exhaust pipes. Bad exhaust muffler could also cause this. Hope this helps.
ON THE ENGINE Or more correctly its under the exhaust manifold, which will be very hot after the car running.
Depends on which part. The exhust manifold can be glowing red, while the most of the engine should be slightly below the boiling point of water.
Feel the exhaust manifold at each cylinder as it is running, if an injector isn't working the manifold at that cylinder exhaust port won't get hot. Some of those Ford diesels had a problem with the electrical connection where the injector harness passes through the valve covers.
