If it is just when starting and blue smoke it will be valve stem oil seals or possible valve guide wear leave ticking over five mins then rev up if it smokes and clears that will confirm it assume you have checked there is not too much oil in engine

First of all what color is the smoke. blueish smoke is oil. white smoke is water or coolant. if the head gasket is blowen you could check your oil with the dip stick. if the oil is way to full the means that there is water in the oil and oil floats on water. the also sell a kit at your local auto store to test your coolant the see if there is exhaust gasses that have entered you coolant. that kit is for when you have a small leak.

My 2005 gmc canyon just started blowing smoke out tail pipe but it doesnt do it everytime i start it. is this bad?

Possibly a leak in the head gasket. Take out the plugs and see if they are water wet. Run a compression check.

I need to change the head gasket on my 4 cyclinder tacoma it is getting radom miss fires

we usually replace head gaskets when there is an overeating problem or leak problem, if you saw coolant in the spark plugs or if the misfire come with a thick white smoke from the tail pipe, then this is reason enough to do the head gasket job.

for random misfire we got spark plug wires high resistance,
weak coil,
bad fuel,
weak fuel pump.
bad injectors.

It is over heating but not smoking from front or back. i had a man look at it and he said when he took the spark plugs off coolent was shooting from it does that mean i have a blown head gasket

Hello chlon_bolden: My name is Roger and I will offer some information. If you have anti freeze blowing out the spark plus hol? You have serious problems. You should have a very bad misfire in the engine and white smoke out the tail pipe. Either the head gasket is bad or worse case the head or heads are cracked and/or warped. The only way to tell is to remove the heads and inspect them. All of these are expensive. Should you need further help please just ask. Please rate the answer. This way I know it was of use. Thank You for using Fix Ya. ROger

Having trouble sttaring cold takes many attempts

white smoke points to a head gasket issue, If your coolant is low and smells and looks weird then get the car tested to be sure.

1986 Honda Civic overheating and blowing white smoke out tail pipe when I start it up

Not good news. Sounds like a blow head gasket.

Are you losing coolant?

My truck blows white smoke

There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck
