I FINALLY got around to doing an oil change on my new (for me, anyway) '85 pick up, 318 engine. It needed it!! The oil was thick & filthy.
After crawking under the truck, I discovered why the oil was so dirty.
The oil pan drain bolt is ALL buggered up, rounded off, and quite solidly stuck.
Any/all wrenches and vice grips I can find will not budge this stuck, rounded off bolt.
What are my options here?
Can I center punch it into the pan,tap and thread an oversized one? If so, will the partial bolt inside the oil pan make some trouble?
Or should I find a used oil pan and swap it out?
Your thoughts and opinions, please.
