wow. the drain plug, i've had some tough ones. but none bad enough to make a thread about. i mean, the motor oil practically keeps it lubed for you without the use of PB blaster or WD-40. anyways, like they said, breaker bar or extension. leverage is key on almost any stuck bolt.
So you're still figuring it out then? Damn what a tough challenge. How much trouble to you usually have changing a tire? Just wondering, totally unrelated.
