Ok guys so I have a 08 Charger with 2.7 engine it is locked up on 2 cylinders I know the preffered method to correct this is a rebuild but no money any other suggestions like marvel mystery oil or something thanks in advance.

 

That depends, how did it get locked up? Sitting for a long period of time or water ingestion?

 

Water injestion.

 

Then you likely bent/broke things as well. You can pull the plugs, and get the water out, but, expect that you will still only have a four cylinder engine, that won't last very long, if it will start at all.

 

I bought the car from the person that caused the damage just trying to see most cost effective way to handle it.

 

Given my choice, I would simply replace the engine. Hydrolocking an engine does serious damage, and it isn't always apparent. Depending on your budget, you could go with a new long block, or, just get a low mileage replacement from the junkyard.

 

Well I have the facility and knowledge to rebuild so I think I will go that route.

 

If you have bent or broken rods, you should replace the crank as well then. Otherwise, the engine may not last long..... If the block got damaged as well, just replace the whole thing.
