White smoke would indicate you're burning engine coolant. Black smoke is usually raw unburned fuel, and bluish smoke is oil. Has the engine overheated recently? Is it losing coolant without any external signs of a coolant leak? You may want to do a block check to see if you have a blown head gasket....

SOURCE: 97 Nisson pickup smoking white smoke (a lot)

this indicates that you have a blown head gasket. you may not have water in the oil pan but it's because the water is not leaking into your oil galleys,but instead leaking into the cylinders and being burned hence the white smoke.. there is a big myth that you will get water in the oil with a blown head gasket . there might be trace amounts but the only time you get water in the oil is if the heads crack or the block cracks othere wise most times it's just getting burnt in the cylinders,hence the great amount of white smoke. please rate this thanks.

SOURCE: my buick centry is missing real bad.

Make sure you do not have any vacuum leaks and the egr is functioning properly. Next do a compression check and see if you have a low or dead cylinder. I hope this helps you to find your solution. Merry Christmas! and God Bless!

SOURCE: 2000 TDI - Lots of white smoke at cold start.

Sounds like your injection pump timing is off, an injector is leaking or a bad seal on your IP.
VW dealers have a horrible reputation when it comes to TDI's. Check out the posts over at www.tdiclub.com Those guys are very knowledgeable - and the first thing they'll tell you is don't take it to a dealer.
You can probably find someone in your area that has a copy of Vag-Com (scantool software that vw uses) software that could look at your timing. It definitely sounds like your dealer was throwing parts at your car because they didn't know what your problem is. If I were you, I'd copy and paste your post from here over at www.tdiclub.com

2006 ford Taurus I change spark plugs and wires and coil packs but it is missing real bad and u can smell gas it runs real rough

I had a similar sounding problem on my old 1993 Lexus. In my case it was the car's computer. The capacitors on the circuit board went bad and it caused the fuel injectors to be constantly open. This flooded the engine. It would run, but very badly and it blew a lot of white smoke out the back. I replaced the capacitors and the problem went away.

Pontiac Codes P0300 and P0133 when cold won't start unless you punch the gas

White smoke in the exhaust is a sign of water in the engine. What is the level of the radiator? You may need a new head gasket or heads.

1999 gmc suburban-smoke comes out exhaust and smells like gasoline

If the check engine light is not on, I would check the fuel pressure regulator and for problems with the fuel return line.
If you have a leaking injector you should get a check engine light and code for a cylinder miss.

ALOT OF SMOKE FROM THE EXHAUST

Blue smoke is oil and means you have internal engine damage.
White smoke with a sweet smell means you have a blown head gasket (check antifreeze, if it's low that is another sign)
White smoke with no real smell is water in the gas tank. Grab some water remover.
Black smoke is a sign your burning to much gas, you need a tune up.

Backfiring, rough idel

I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.
