SOURCE: blue smoke from tail pipe 98 neon no leaks i can see

piston rings or valve stem seals. Both will cause excessive oil consumption and smoking. Worst case scenario: head gasket/head/block issues.

SOURCE: white smoke from tail pipe

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 the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

I would start with a full tune up. If it has never been done then that is the best way to start. Make sure that you gap your plugs. NGK plugs are the best for any and all Honda's. Let us know how it goes.

SOURCE: I have a p0303 trouble code on my 1999 Passat.

coil packs very prone to failing... check compression for good readings (at least 100 - 120psi) if okay try new spark plug as these can fail under load and its the cheapest part to replace to eliminate. if misfire still present swap cylinder 3 coil with cylinder 1 coil and see if fault code moves to cylinder 1. hope this advice helps

Why is oil in the exhaust and the bus is smoking

Sounds like the oil rings or one of your cylinders has a crack. Do a compression check; all cylinders should be above 100+. I am guessing that the 'smoke' is whitish in color. You can also look at each spark plug; if one or more has oil on it this will tell you which cylinder or cylinders are bad.

Starting to see white smoke coming from my tail pipe, what could it be?

**** smoke is water vapor, could be a sign of coolant gettting into the combustion chamber, best to get it checked ahve the coolant pressure checked, and remove the sparkplugs, they should be dark colored if any are a whitish color i would suspect a head gasket

Tham@look.caOver heating-runs rough at start up-sets code ...missfire #2 cylinder.

Either the fuel injector is blocked or not functional on #2 cylinder, or the coil pack is not firing the spark plug there.

Check coolant level and if thermostat is stuck closed and if the fan is not running for the radiator.

1999 grand am gt 3400 v6

If white smoke is coming out of your tail pipe is is burning antifreeze. However have it checked closely. While it could be a head gasket, the 3400 is noted for the intake gasket leaking. Have a pressure test done before you pay for something that you don't need.

Also there is a way to permanently repair the head gasket if it is a real leak as long as it still runs. Check out Barr's Leak head gasket repair and follow the directions to the letter. do not skip any thing. It works I have repair a dozen cars with this.

Hope this helps

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.
