Mufflers and tailpipes are components of an exhaust system. The tailpipes guide the exhaust away from the engine and into the muffler. The muffler reduces the noise coming from the engine through the tailpipe.

1988 Silverado 12 ton 150000 miles when running a lot of white smoke comes out of tail-pipe It does this when you start it or when driving what causes this?

White smoke is an indicator you have a head gasket leak. The white smoke is actually water or coolant mixing into the combustion chamber with the fuel and air. Have you noticed a bit of a rough idle? Have you looked at your coolant level lately?

What is causing white smoke to come out of the exhaust for a few seconds when you first start your car?

White Smoke from ExhaustA little whitish vapor in the first few seconds after start-up is nothing to worry about; it's condensation being blown out of the exhaust system and will quickly disperse. Smoke that persists, however, is cause for concern.

* Black smoke comes from partially burned fuel. This indicates that the air filter or fuel system needs to be serviced.

* Blue smoke indicates burning oil is a bad sign. Clouds of blue smoke on start-up may indicate worn valve-guide seals, valves, or piston rings, the latter of which can mean a cylinder-head or engine rebuild is needed.

* Billowy white smoke may indicate that coolant is getting into the engine. Another bad sign. This can be a result of a blown head gasket, damaged cylinder head, or even a cracked block. All are expensive repairs.

How would you remove an old rusted tailpipe that's broken off at the point where it goes into the muffler?

Heres how i eventually did it ... 1. Using needle nose locking pliers i held the pipe to the muffler so that it wouldnt get knocked back into the muffler. 2. Then using a cold chisel i made a gap between the muffler (the part that houses the pipe) and the pipe. I did this so that the pipe could be cut through without also cutting the muffler. 3. Then using a power saw with a metal cutting blade i cut through the tailpipe. 4. Then I was the able to crimp the edges of the pipe up and pull it out. 5. Have a beer for a job well done !!!

Why does nothing happen when you step on the gas?

You really need to give us a little more information. I'm presuming that the car starts OK, right? When you press on the accelerator, with the car in neutral or park, does the engine rev up? Is your transmission auto or manual? If the engine revs up, does the car not move when you put it in gear and/or let the clutch out? Inquiring minds want to know! FriPilot

How do you make a silencer?

First, you need to make sure you stay out of prison.

You start by figuring out if they are legal in your state. Don't trust the word of a friend, or some guy at the gunshop. Read the actual statutes, most states have them online. Look for "silencer" or "suppressor". I only know about Minnesota. They are not legal here.

Once you know you won't go to to state prison for this, you need to make sure you won't go to federal prison. You do this by submitting ATF Form 1, Application to Make and Register a Firearm, to the Bureau of ATF, NFA Branch, along with a check or money order for $200 and getting their approval.

Once this is done, and you have the application with the canceled tax stamp in hand, you can go and make your silencer.

The simplest silencer is a length of pipe with caps and several rubber baffles inside.

What causes black sooty exhaust?

When you get past 55 mph or if you use the heater the check engine light comes on why?

No idea to be honest, but i have a 95 Corsica with a similar problem that will turn the Service engine light on after a while of driving highway speeds, or after reaching highway speeds and slowing down again. After getting the code read i found out it was for the EGR valve sensor. Basically meaning that its positioning fine at normal in town driving but not working as it should at higher speeds.

Again i can't assure you this is a positive solution but i would recommend running your car as you would normally get on the highway and then while the light stays on going to AutoZone (They will run service engine soon checks for free) or a mechanic you trust. hope this helps.

What is wrong with your car if there is white smoke coming from the tailpipe and the oil is not milky on the dipstick?

White smoke from the exhaust pipe indicates that the engine is allowing water into the cylinders. The water then boils in the cylinder and exits the engine as steam (white smoke). This could be be from the inlet manifold (especially if the engine is a V), it could be a head gasket (leak between the water jacket & the cylinder). Or worst it could be a cracked cylinder head.

Or, you're burning oil and you need an oil change.

Why is radiator fluid leaking and white smoke coming from the exhaust?

What causes loss of power and white smoke from the tailpipe?

Loss of power and white smoke from the tailpipe typically indicates that coolant is entering the engine's combustion chamber, often due to a blown head gasket, a cracked engine block, or a damaged cylinder head. This coolant vaporizes during combustion, producing white smoke. Additionally, the presence of coolant can lead to reduced engine performance, causing a noticeable loss of power. It's crucial to address these issues promptly to prevent further engine damage.
