Hit the weights!

 

I used my impact gun and the dp bolts came off like butter. If you can't get access to one. I suggest you use liquid wrench and an extra set of hands. If that still doesn't work go by yourself a propane torch. Heat the nut a while until it turns red and voila it'll come right off.

You should honestly invest in a compressor and an impact gun you'll love it.

 

^^^ I miss my impact......

 

i have the entire set of these and the are f'in awesome

 

Breaker bar works fine with some muscle. No need to heat things up unless you're taking out an O2 sensor.
