2 bolts undo bottom flange, remove any heat shields over manifold, remove side bolts, dislodge and disgard the manifold, buy a 2nd hand one from a dismantler or new, buy new exhaust manifold gasket and flange, Assembly is in reverse, remember to screw in all the bolts before you tighten any of them, use an anti sieze on the threads. Good luck

SOURCE: there is smoke coming from a crack in the exhaust manifold

Hi

Most unusual for the exhaust manifold to crack, normally any leaks are usually due to faulty manifold gaskets, or the down pipe sealing ring.

I am sure if you lubricate the fixing nuts well, before removal of the manifold, this is what you will find.

Good Luck !

Give me feed back if you like.

A FixYa rating would be Nice...Thanks...John.

SOURCE: possible cracked manifold

Take it to a muffler shop, they work on exhaust problems all the time and may just need a new gasket from the collector flange which would not be that expansive. Almost all of them will inspect for free since there looking for your business.
I have not sean exhaust manifold go bad before the whole car or truck and the exhaust pipe is stainless so good chances are that it's the flange gasket or the bolts may have broke due to time and vibration.
Good luck and keep me posted.

SOURCE: Replace 2003 Chevy S10 V6 Exhaust Manifold

On the studs on the bottom be sure to soak them with a good penitrating oil over night. Then on the removal if you feel like they are binding work them back and forth. They may break but you should get new studs with the new one. On the head side just be carefull, if you break a bolt off in the head you have real problems then. Not really complex just use your head and don't be to forcefull.
Good Luck

2000 gmc 3500hd 7.4 after the trucks gets up to temp it starts back firing and sounds like a spark plug blew out .


Simply a 'spitball' guess, but it almost sounds like it could possibly be an exhaust leak either where the manifold mounts to the head or a cracked exhaust manifold.

I'm not sure if that engine came from the factory with exhaust manifold gaskets or not.

Crack or gap is closed while cold or cooler and opens up the crack or gap as the manifold get warmer or hot.

Hope this helps.

Had exhaust manifold replaced since then my 2001 caravan bucks and blows black smoke little to no power


if you replaced the manifold because it was cracked the look for a plugged cat convertor..the cracked manifold was probably letting the exhaust escape..now it builds too much back pressure

Exhaust manifold


A cracked exhaust manifold should not effect your motor unless you have an exhaust driven turbo or something depending on exhaust back pressure to be there. I know where I live you can not get a vehicle with exhaust leaks infront of the passengers compartment inspected though so you may want to have the leak fixed for passenger safety.

When driving i can smell gas in my 2000 lexus es300


possibly your O rings which isolates fuel injectors from engine block are getting old and letting gasoline go out. it is very dangerous since it can cause fire. do not drive.

another cause is broken loose or cracked fuel lines. this is equally dangerous since it is under hood close to hot exhaust manifold.

if smell is from exhaust manifold, which means not the smeel of gasoline but exhaust fumes, this can be caused by broken exhaust manifold or a crack on it or problematic exhaust manifold gasket.

Blowing anitfreeze out the tailpipe. I know this means a head gasket. When the engine runs, it blows antifreeze out the passenger side of the engine at the exhaust manifold by the middle cylinder. Does...


could be just head gasket and bad exhaust manifold gasket (coolant leaks past head gasket into exhaust port then leaks out of exhaust manifold gasket)
or it possible that head is cracked too
Only way to know for sure is to remove head and inspect it

What repair is needed to stop exhaust manifold leak and what do i need to do the at home repair


It depends on the leak. First of all - see if you can see any cracks on the manifold - telltale signs would be a visible crack and black residue around it from exhaust. If you see that the manifold should be replaced. - welding would be a possible alternative. If there are no cracks - check all the nuts and studs to make sure they are tight. Make sure the exhaust pipe is tight and not leaking at the connection. If everything looks tight and secure - change the exhaust manifold gasket. All of that could be done at home depending on your comfort leel with the tools and time available.
