Leaky muffler type sound from engine when under a load


check for a leaking manifold gasket or cracked manifold. If it is a front wheel drive car there may be a flexible bit near the engine to allow the engine to move in the mounts . This bit of flexible exhaust is known to crack under the brading.

1995 runner looses power up hills and coasting. am going to repair, need to lead mechanic to area to check. exhaust system or head gasket? also smell antifreeze after turning motor off.


sounds to me like a bad headgasket. if they are bad. you will loose power and it will leak if bad enough. have a good one ! pull out oil dipstick. if it is a foamy substance on stick, then you have a bad head gasket. Pressurized exhaust gas can be forced into the coolant system through a cracked head gasket. When this happens, oil particles from the engine will often be blown in with the gas, causing pollution of the coolant system. The result is visible traces of oil in the coolant tank.

I got a 1999 gmc sonoma 4.3 v6 vortec I have strong exhaust fumes coming threw the a/c vents while the a/ is on


You have a leak in the exhaust system. Have it looked at soon. You don't want to be breathing carbon monoxide while driving. If you hear a "ticking" sound while the engine is running (more predominant with a cold engine) it's most likely an exhaust manifold leak, either a bad gasket, broken stud or cracked manifold. Other possible causes could be the "donut" gaskets that seal the Y pipe to the exhaust manifolds, the Y pipe to catalytic converter gasket (if equipped).

Exaught manafold leak


You state that car makes a loud noise when driving. Do you notice the sound more when you accelerate? If yes, then it could be either the exhaust manifold gasket or the donut gasket. The donut gasket is where the exhaust pipe connects to the exhaust manifold.

WHERE TO LOOK FOR EXHAUST LEAK


There are several areas to check for possible exhaust leaks. i will list them below.

1. Exhaust manifold gaskets - This will be the most common area. There is a gasket that separates the block from the exhaust manifold. these gaskets can fail, thus, causing a exhaust leak at the manifold.

2. Lower manifold gasket(donut gasket) - This will be a possible leak spot as well. This small circular gasket is placed in between the upper exhaust pie and the lower side of the manifold. It basically separates the pipe from the exhaust manifold.

3. Exhaust pipe - The entire pipe can rust overtime, thus, creating small holes along the pipe structure. These holes will cause the exhaust to leak ,thus, filling the vehicle will moderate fumes and causing louder than normal engine sounds during revving.

4. Muffler - This component can also deteriorate to the point that it cannot filter out the noise. It will also cause leaks as well.

You will find the leak in one or all of the areas stated above in the list.

How do i replace my donut gasket in 1994 s10


Take the exhaust apart at the collector , this is where the gasket is. its a seal on the piping to seal at the collector , it may be hard to c it cause it will be dirty n greasy and could look like a solid piece of the exhaust , but its a donut shaped ring that slides over the end of the pipe.

Exhaust and coolant problems are two separate things. It's possible the donut that connects your exhaust manifold to the pipe came loose or the exhaust manifold or pipe has a hole from rust. You obviously still have a coolant leak somewhere. Start the engine and look under the car to see if you can see coolant dripping. It's either coming from one of your hoses, thermostat, water pump or coolant lines that run from your radiator to your transmission (if you have an automatic). There's a good chances are if it's still leaking the new water pump may not have been installed correctly. Also check your oil to make sure it's not milky white. That means your oil is mixing with the coolant from a blown head gasket. That can happen if the engine overheats severely. Head gasket repair is very expensive.
