Re: [DML] Oil Pan Removal

Heli-coils are good but are not great. The heli-coil is just 
a "spring" like material and it dosn't "bite" into anything when you 
install it. With that said if you try to remove the drain plug with 
the Heli-coil chance are the heli-coil brand will come out with the 
plug. Also if you try to tighten the plug tight to it's torque 
setting you can rip the heli-coil right out and have another problem 
on your hands (happened to me when I tried to repair a waterpump 
thread) There are other better ones...I used ones from Time-sert ( 
http://www.timesert.com/ ) to repair the threads for my exhaust 
manifold bolts. They are solid inserts with a flare at one end to 
seat it in the metal along with teeth to bite into the metal so it 
dosn't come out when you try to remove the bolt...or in this case 
the drain plug. They have metric sizes up to M18, I don't know what 
the drain plug size is.
