Possible blown apex or side seals on the rotors. If that's the case, a full teardown is needed, and you'd probably do well to go with upgraded seals if possible.

I went to put oil in my 2000 Firebird notice a little smoke coming out where i was to pour oil do i have a serious problem ?

Most likely not. Those fumes/smoke are produced constantly by your engine. When it is running, the vapors are sucked into the air intake and burned with your gasoline. The PCV valve is designed to do this job but when the engine shuts off the valve stops drawing the smoke away and it just sort of hangs there until it settles.

PCV = "positive crankcase ventilation"

My 1985 vette starts up cold good and no smoke but after warm up it don't want to crank when it does it has black gray smoke for a min what's wrong

not starting when it gets warm could be a starter problem, the amp draw is probably to high for the battery to supply enough power to start. starter draw should be around 150-200 amps. the black gray smoke is too much fuel that isn`t being burnt. if the starter draw is too high then there isn`t enough voltage for the ignition system to fire the plugs properly causing the smoke.

2008 6.4 f350. blowing tons of blue smoke for the last 12 months

Blue smoke means burning oil. Black smoke means running too rich (too much fuel in the air/fuel mix). If it is blue smoke:
If it blows blue smoke only shortly after starting, it means oil is leaking into the cylinders from above, through the valves. This us typical of older engines, and can be repaired without removing the engine from the truck (although it is still expensive). A 2008 should not have this kind of problem.
If it blows blue smoke all the time, it is bad piston rings or scored cylinder walls. Oil is leaking from below up into the cylinders. This is bad news - any solution will require removing the engine from the truck and complete disassembly (i.e. a rebuild). No engine oil treatment will make it go away, regardless of what the label says.
It is very, very rare in modern engines for a well maintained vehicle with less than 100K miles to need a rebuild. Damage such as this usually comes from not changing oil AND the oil filter often enough. 3-4000 miles for conventional oil or 6-8000 miles for synthetics. If using synthetic, be sure to get a high quality filter designed to be effective for the synthetic oil change interval.

When I first start the car a puff of blue smoke comes out the back after driveing for awhile a strange smell is in the car?

This sounds as if you have a rather High Mileage vehicle. (100,000+)
The puff of blue smoke is oil being burned in the cylinders. When the engine is cold, it will burn some oil, usually sucked in through the Valve Stem Guides.
Then after the motor warms up, and all the metal parts swell a little, it stops smoking as much. It is STILL smoking, but not enough for you to see it.

Obviously, you are losing engine oil, so check the oil level often, and refill/change as neccessary.

The 'strange smell' could be many different things. My best guess is that you have Oil Leaks on the engine, which is dripping on to the Exhaust Manifold, and getting burned there. Usually a Valve-Cover Gasket leak. When the car is all warmed up, open the hood, with the engine running, and see if there is any whitish smoke rising from the motor. if so, you have a leak on to the manifold. A very common problem, easily repaired. Or, you may have a leak in the heaters' Core, which will leak Anti-freeze into the cabin of the car. That would smell sort of sickly-sweet. This will be a much more expensive problem to repair.

Anyway, it sounds as if the car is in need of some maintenance.

Antifreeze pushing cap on over flow resivore and low heat .Could this be a leaking head gasket? antifreeze not draining back out reservoir

It sounds like you need a new Radiator cap for the overflow style Radiator. The overflow style has a recovery vent which draws the water back through the radiator neck and into the engine. Low heat levels are also a sign of a water shortage.

Your antifreeze strength needs to be 50/50. This sounds like there is an ice block inside the Radiator or engine. Get the strength of the antifreeze tested.

You could have an internal leak; you need to have the system pressure tested. The overflow tank should drain back into the radiator and it relies on a sealed system to work. If you have a leak, there will be no Vacuum pressure to draw the antifreeze back into the engine.

It could be a head gasket leak, or a leaking heater core, or bad radiator or a bad hose. The pressure test can be done by anyone with a gauge. You could try Autozone or Oreillys for their loaner tools. Ask for a Radiator tester pump. You can also have the cap checked.

Radiator and A/C shops do this test routinely. A real Service station used to do this routinely until they went self-serve.

I hope my solutions give you a few alternatives because a head gasket is a costly repair. I hope you find my solutions very helpful.

When first started black smoke comes out exhaust pipe,, what could this be

Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head. Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix. Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

Will not start, clicking in engine, and smoke or steam coming from engine

Sounds like something is shorting out starter.
Disconnect battery terminals,get shop manual and inspect and clean off and repair any wiring to the starter.
Reconnect and have the battery checked out (Open circuit voltage test, and load test.), do starter current draw test if a-ok put back into service. Normally I would have you do a voltage drop and current draw test on starter circuit BUT SMOKE MEANS THE SHORT WILL BE OBVIOUS. Good luck and be careful I'v eseen these things start fires and cook batteries.

The engine runs ruff like its miss firing i have a engine code p0174 its makeing like a knocking noise in the engine also it acts like it needs a tune up shaking while running

p0174 means that the computer has detected that the engine is running lean (too much air or not enough gas). Start engine and listen for a whistling noise. If you can't find it you may have to go to a repair shop so they can do a "smoke" test to make the leak visible. If not repaired, can lead to major damage such as burnt valves.
