If it is leaking or rotted
No
If NJ has an emissions standard, no. You'll have to repair whatever is wrong before the vehicle will pass emissions.
To pass emissions you do.
Get it fixed.
okay i just found out a carbyrator will pass emissions you just have to be able to run the emissions controls like catylist convertor and air injecton pump if you have one
If it didn't have emissions controls from the factory you don't have to pass any emissions test, check with your state as some are different, especially California.
yES IT WILL
No, but there's a permanent fix. The white smoke means you have coolant getting into the exhaust. Which means you've probably got either a leaking head gasket or a leaking intake manifold gasket. Replace them, and that'll solve the problem, as well as increase the longetivity of your engine.
There are variety of reasons that it may not pass emissions. It could be because of a bad catalectic converter to oil seeping past the rings or valves.
Not if they test emissions.
yes but it will not pass the safety check
