Answers :

Have your oil checked and make sure there is no coolant in the oil.Also make sure there is plenty of oil in the engine.If you keep driving it it could get worse and more expensive to repair.
Sounds like you have a rod bearing going out. Take it to a reputable garage and ask a mechanic to take a listen to it.
