Mufflers and Tailpipes
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.
What can cause white smoke from the exhaust?
Here are the best answers compiled from s.com contributors: It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill...

Why do tail pipes on pickup trucks come out to the side and not the rear?
shorter pipes mean less cost to manuf. = mo profit. And it looks sporty. My truck's tailpipe is bent 90 degrees with the tip extending another 12-14 inches out behind the right rear tire. The pipe would be the perfect length without that last bend and if it exited straight out of the vehicle's rear. Truck tailpipes exit the side because when towing a trailer rear facing pipes can cause exhaust fumes to enter the passenger compartment by hitting the trailer and...

What would cause white smoke to come out of the tailpipe?
If you are having a lot of white smoke all the time the car runs then check for coolant mixing in with the oil,look for water in the oil when you check the oil or milky brown oil. This produces a white "steam" that is very thick to come out of the exhaust. If your engine temp. gauge is very high and over heats you probably have a blown head gasket.

What does blue smoke from the exhaust mean?
Well unfortunately you can count on it meaning you'll have to get your wallet ready for a workout. Blue smoke could indicate a few different things I guess. However it is my own experiences that tell me what is happening is your motor oil is leaking past your piston rings and getting into the engine cylinder and mixing with your fuel and ultimately burning along with the gas. That leakage is getting compressed with the gasoline in the combustion chamber and the...

How do you remove muffler on John Deere stx38?
I'm having the same issue. I'm trying to replace my front axle and I need to remove the muffler to get to the axle bolt. Please help. I recently replaced the front axle on my STX38 so I took off the muffler as well. The muffler's heat shield needs to come off first, I think there's just two bolts holding that in place on the front of it. If I remember correctly, there were 4 bolts total securing the muffler. There are...

Don't want to doubt you, but I'd definitely check to make sure it feels lightly oily or even soak some a few drops into a paper towel and see if it ignited (careful of course). Assume it's not running rough / missing occasional firings, right? This can also be caused by a defective fuel pressure regulator. (Ford Ranger) ...

How do you convert a 1988 Caprice Classic from single exhaust to a 'true' dual exhaust?
The only main problem you are going to have is there is no dual exhaust cross member available as far as I know, but a good custom pipe bender at a muffler shop can pancake the driverside pipe. Which means they square off the pipe where it won't hang below the crossmember's nonexistant hump. If you run dual after market converters it should pass emmissions. If you want the look of duals, go to Big Al's muffler and break. They do cat-back...

What might cause white smoke from the exhaust after having a head gasket repair done?

Why would white smoke come from the exhaust of a car when it was restarted after overheating?
This means that water is passing through your exhaust system which usually means that either a head gasket went bad or crack or warped head. Answer Did you repair the car first? Because if not your engine is probably hurtin' (blown head gasket or warped head). The most common leak in a blown head gasket is the anti-freeze. White smoke is anti-freeze burning (or boiling) and you probably noticed you're losing anti-freeze from the reservoir. Also check your oil for overfilling and a greenish...
Will driving with a blown head gasket damage the car?
Although rare, if it overheats the block could crack. If the coolant and oil mix (keep an eye on the oil condition), it could wipe out the bottom end of the engine. If the cylinder fills with coolant enough and the piston tries to compress the liquid, it could do damage to several parts including twisting the crankshaft. It would be smart to not drive it, but I guess life is all about risks and opportunity costs. More Information: I was driving home...
