Yes. It also depending on what kind of stop leak and how much is used.
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
no but it may cause it to stall if exhaust is blocked
Head gasket or cracked head
black is excess fuel
Radiator cap
Excess fuel causes black smoke.
May be a bad fuel pressure regulator.
A radiator cap would not cause a leak! However, if the radiator cap is holding pressure, other weak parts could signal issues in need of attention.
I would suspect a clog in the radiator.
radiator cap
White smoke is a symptom of a blown head gasket.
A leaking radiator hose would NOT cause this to happen, you have 2 problems with this vehicle.
