I have an 1982 suzuki gs g. a few days ago someone bumped into and knocked it over in the night, the next morning when i tried to start it, it almost turned over, but a bunch of blue smoke came out and it...

Since the bike laid on its side all night,oil got into your top end and just needs to be run till all oil is cleared out.Clean the air box and anything connected to it.The breather from the crank case runs to the air box,that's why there's oil in it.Should only be a fine mist when running.This is the bottom ends only way to breathe,piston goes up,pulls air in from breather hose.Piston goes down,makes pressure and has to have a means to releave that pressure from the cases.This is how the bulk of bigger bikes are set up to opperate.Just laying on it's side for any length of time won't hurt anything other than what I just said.Takes a bit of time for it to finally clear all oil from tha breather system,and you'll have to change your plugs a coupl of times.Use NGK's that burn oil.

Seat alhambra leaking oil from exhaust and smoking

The most likely cause is a worn bore and the oil is leaking past the rings. It is possible that the oil is entering the combustion chamber through a breather.

Lots of oil under my f150 crew cab not at head gaskets

pcv valves allow oil fumes to be burnt through the motor so the smoke would unlikely to coming out from under the hood.. To get you problem there has to be raw oil moving onto a hot surface such as an exhaust pipe. Check all obvious oil leak points such as front crank shaft seal behind harmonic balancer. check transmission oil cooler lines if fitted. check rocker cover gaskets as they can leak small amounts of oil directly onto the exhaust manifold mostly from the rear of the head. check for oil leaks at the rear main seal at the mounting cover. finally if the pcv valve is faulty then excess ive crancase pressure would have pushed the sump gasket9 or both front and rear seals) out of place and the oil again would be getting to the exhaust pipe.You say you have just had an oil change done check to see that the sump is not over full

Oil smell smells like it is burning oil last oil change was 3 months ago

Common causes of smelling "burning" oil are:
  1. a leak in the valve cover gasket. When oil leaks from the valve cover gasket, it will often burn off on the manifold.
  2. a blown oil seal causing oil to burn off on the exhaust system
  3. check your exhaust for "blue smoke" a sign that the engine is actually burning oil. Just guessing here but a 16 year old Volvo is bound to have quite a few miles on it.
I hope you found this post helpful in diagnosing your problem. Thank you for using Fixya! Greg

Burning oil but runs very strong with good plugs

Are you sure it's burning the oil? Check your oil pan gasket and valve cover gaskets for leaks. Is the car smoking? (light grayish or white smoke is oil, black or dark bluish is fuel) Could be bad valve seals. Also, main seals can leak oil out onto exhaust parts.

My 04 rmz250 is overheating. It started smoking 3 different times when i took it out the other day. Id let it cool down for a few, continue riding and about 20 minutes later it would start smoking again....

Several things here. Do an oil change, 10w40 motor oil. Run premium gas and install a new NGK spark plug one heat range colder than stock. It sounds like you have an air leak causing a lean fuel mix. Check the carb mount bolts and the intake manifold bolts for tightness. Also set the valve clearances with a cold engine > .002 intake and .003 exhaust. Check for any cylinder head leaks. This would show up as oil on the cooling fins at the base of the cylinder head. Tighten the head bolts if needed.

Smoke alot

sounds like the bike is in need of new piston rings especially if that much oil is blowing on such a newer bike. if the crankcase is not overfilled, then focus on rings especially if the sparkplug is oily too.
