i think i may have a blown head gasket or a cracked head... although this has not been comfirmed just a strong chance that it may be the case.. so i bought Bar's Leaks head gasket fix solution. now my question is it bad to use this if you do not have any leaks? will it mess anything up?

 

I would NOT use any kind of stop leak your just asking for more problems such as clogged rad. heater core, thermostat.

 

X2,that stuff is just bad.

 

i would not use bars, i would recommend a product called dike. it comes in a small bottle for about $15.00. it only works where there is oxygen present, and it will not clog your heater core like other products will. i will be using dike on mine as soon as we get it back in stock.

 

or just do it right and fix the leak..........no magic in a bottle.

 

from personal experience and stupidity when i was in HS. any bars leak products has BAD news written all over it. bars leak was the culprit of the death of my first 4.0L motor. never will use any of bars leak again.
