This depends on where the leak is. A hose could be loose or broken or there could be a radiator or engine leak. The area of the leak needs to be found to be able to diagnose.
a vacume leak, spray carb cleaner around the eng while running to locate the leak, may even be the booster itself
Sounds like a vacuum leak.
That depends on where the oil leak is, is it in the motor self or is one of the seals leaking?
Check water pump and pump gasket.
Cracked cylinder head, blown head gasket, engine block or intake gaskets.
Excessive crankcase pressure will cause this problem two possible causes are worn/broken piston rings or a blocked engine breather.
It's probably a head gasket problem.
my warrior spit out a gas and oil mixture out of the breather because the gas shut off wasnt working and the carb was letting the gas leak by so it actually pretty much overfilled the engine so bad it would fill the air box witht his mixture
Yes it can.
check your water pump. As well as your thermostat housing, and any coolant hoses/connections.
fuel leak on top of what type of engine, gas or diesel?
